Android KitKat 4.4.2 for Sony Xperia Ray

I have got so many requests from so many readers to release KitKat for Sony Xperia Ray. So, most of the readers of NetMascots is eagerly waiting for the Android KitKat release. I have successfully installed android KitKat 4.4.2 on my device and it is working fine without any issues. Before going to try this ROM, I’m strongly recommending you to read my complete review on KitKat 4.4.2 and Xperia Ray.

I hope you enjoyed the taste of KitKat from my review. What do you think? Awesome? Then, why are you waiting to let’s proceed to Install KitKat 4.4.2 on Sony Xperia Ray?

How to Install KitKat 4.4.2 On Xperia Ray – Procedures

Checklist Before Proceeding:

  • Backup your contact, SMS and call logs. Warning: All your contacts, SMS, and call logs will be erased when you install custom ROM. Note: Many apps are available in play store to help you backup your SMS, call logs and contacts.
  • Backup your apps and data (If needed). I’m recommending Titanium Backup root to take a full backup of your apps including app data. Warning: All your apps will be deleted while installing this ROM.
  • Phone must be charged minimum 80%.
  • Enable USB debugging.
  • Phone must be rooted (If you are using any Custom ROM, then it is already rooted!)
  • The bootloader must be unlocked.
    Note: To unlock the bootloader,  read “Step 1” in the Jelly Bean Installation tutorial.


1. KitKat 4.4.2 ROM Files And Gapps

Download KitKat Custom ROM Files From Here (Link Updated On 28/Jun/2014)

Download Folder contains:

  • Kernel (boot.img)
  • KitKat ROM (pac_urushi_4.4.Alpha-1_20140314-072251)
  • Gapps (gapps-kk-20140105-signed)

2. Latest Version Flashtool: Download From Here

Now you are ready to install KitKat 4.4.2 On Sony Xperia Ray Smartphone.

Steps For Installing KitKat 4.4.2

Step 1: Copying ROM files to SD card

Before flashing you need to copy KitKat ROM file (pac_urushi_4.4.Alpha-1_20140314-072251) and Gapps (gapps-kk-20140105-signed) to the SD card.

Note: If you are doing this step after flashing the ROM, you can’t connect your device in mass storage mode to transfer files to SD card. The reason is, you need to turn on the phone to enable mass storage mode! So, just connect your device to PC and copy the two zipped files to the SD card. DO NOT UNZIP THE FILES.

Step 2: Flashing Kernel

For detailed tutorial on Flashing Kernel(boot.img) Using Flashtool, read this article:

OR See the tutorial video given below:

Step 3: Installing ROM and Gapps

  • Switch on your device and get into the recovery. To get into the recovery, you need to press the volume down button few times while your phone gets booted.
    Note: I repeat, you need to press the volume down button repeatedly (NOT PRESS AND HOLD) till you see the options in the recovery mode. The reason for why I told like that is because, most the readers who installed the Jelly Bean ROM made this mistake!
  • After getting into the recovery, you can use your volume up and down buttons for navigation and use “Home” button to make the selection.

Now you are in the recovery. Please follow these steps for completing the procedures:

  • wipe data/factory reset>>yes – wipe all user data
  • wipe cache partition>>yes-wipe cache
  • advanced>>wipe Dalvik cache>>yes – wipe Dalvik cache
  •>>choose zip from /storage/sdcard0>>pac_urushi_4.4.Alpha-1_20140314-072251>>yes – install pac_urushi_4.4.Alpha-1_20140314-072251
  • Note: Be patient, Installation may take some time. You can see a blue progress bar at the bottom of the installation page.
  •>>choose zip from /storage/sdcard0>>gapps-kk-20140105-signed>>yes – install gapps-kk-20140105-signed
  • After completing the installation, come back to the main menu by pressing the back button.
  • Now go to advanced>>power off to shut-down the device.

Note: Please allow up to 15 min to settle the ROM.

Hurray! You have successfully installed Android KitKat 4.4.2 OS in your Sony Xperia Ray.

I’m eagerly waiting for your comments and feedbacks. Because, your comments are my inspiration to write tutorials and articles.

I have seen some roms which provide the opportunity to move this kind of apps to the sd card so that you have more memory in phone and phone works faster. Second, xperia ray is normally 1 Ghz but I have found a rom which increase it to 1,6 ghz. With this rom will I have still 1 ghz? I am asking these questions because speed is the most important thing for me and I am searching for a fast rom. Thank you so much:)

  5. hello, why it take so long time to install pac urushi 4.4 alpha? can give estimated time it should be? i guess it is like stuck, sorry for bad english

    1. Hi izul.

      Please don’t interrupt or switch-off your device while installing the ROM. It may take 10 to 20 min to complete the installation. So, be patient. You can also see a blue progress bar while installing.


      1. thanks for your reply,i have installed this custom rom, and can’t take the music from Sd card to set up my ringtone,it is impossible? there is no option such as “set this as ringtone”,

        1. Hi Izul

          It is possible. In android, we can set ringtone via file explores or music players. To set a ringtone in Android KitKat 4.4.2, you can follow the two methods given below.

          1. Open file manager and go to the ringtone file>>>Click on the ringtone file to play in apollo music player (or any music players) >>>Click on xperia options button>> Select “Use as ringtone” option. You can see a message like this” ‘music file name’ set as ringtone”. That’s it.

          2. Directly go to music player and click on options button and choose “Use as ringtone”!

          Now, your ringtones are added to the “Phone Ringtones” list. You can change/select ringtones by going to Settings>>Sound>>Phone ringtone

          I hope this helps.


          1. thanks for the helps! 😉

          2. Always happy to help my readers:)

    1. Hi Rangan.

      Please post your comment in correct posts. You are trying to flash jelly bean kernel. So, comment in that article.

      Anyway, your device is not rooted. Do not try to flash the kernel until you have successfully complete the rooting process. So, root your device first.

  11. Hi Akhil K A,

    Goody day. I followed everything in your instruction and had successful installation (Thank you!). I’m just wondering why I’m having random reboots? Any comment regarding this issue?


    Btw, thank you for the Rooting and the SJB installation tutorials.

    1. Hello Tiir.

      Thank you so much for your feedback.

      I don’t have this rebooting issue. But, I’m really sorry for this. Please test the ROM for 4 days and check whether this issue is appears again.

      Let’s see.

  13. installed the rom thanks Akhil

    1. Hey Adam.

      That’s a happy news for me. Thanks for the feedback. If you facing any issues, please don’t forget to update me.


  14. hai akhil
    plz give me the tutorial for how to install walkman app for this ROM?
    becaus the audio quality is less in Apollo musiq(when I was hearing in headset).
    I experience best audio quality in iced bean ROM(it has walkman app).

    other than this (apllo musiq) everything is perfect in this KitKat rom!!!!

    1. Hello Yogarajan.

      I’m not using Apollo music player. I’m using “Poweramp” music player. I’m it is most rocking music player for android users. Simply mind-bowing audio experience and very attractive user interface. It is a paid app. But, you can download a 14 days trial of poweramp. So, just download it from play store and try it. If you are satisfied,I will help you to get a PRO version.


  15. hey akhil
    thanks for this tutorial. Few month ago i installed Super Jelly Bean ROM8. It was the best Rom i installed since 1 year. Very good battery life, smooth and no issues.
    I was happy to read your article over KitKat and try it out. But there is one reasons to go back to SJB8.

    There is no way to disable the “lockscreen widgets”. Thats the important thing for me. Can you help me?

    For me it’s a little bit too much customizable. But the features of 4.4.2 are very great. At this time that’s an alpha ROM. I often look at your page and will try the now ROM again later.

    Dear Tobi

    1. Hello Tobi

      Thank you very much for reading my article and your valuable feedback. In KikKat, you have full control to all modules. So, you can disable screen widgets by going to: Settings>>Lock screeen>>Clock Widget>> and select the particular widget to disable.


  16. Hi. Thank you so much for this tutorial. You are wonderful
    I m gonna install kitkat but fitst i have question.
    Can i install kitkat from 4.0.3, direcly.? (rooted and unlocked bootloader)

    1. Hello Samet

      You can directly upgrade your OS to KitKat 4.4.2, If your phone is already rooted and unlocked.


  17. Hi Akhil,

    I am glad to have kitkat version for my mob. However i dont see Camera functioning properly. It hangs sometimes, which was also there in previous version (JB). Anyway to get that correct ? Other things are working perfectly. 😉 🙂

    1. Hello Sandeep.

      Thank you for trying KitKat 4.4.2 by following my article. I’m not having this issue, but can you please tell when this hanging issue occurs? While capturing or turn on time?


  18. Hey great tut, but i’m stucked in one place

    When I got into recovery mode, i can’t install file. it says ‘Cant open pac_urushi_4.4.Aplha…zip’ (bad)
    Installation Aborted

    How can I fix this? 🙁

    1. Hi Lakzhika.

      Looks like your ziped file is corrupted. Download the files again and try to install one more time. This will resolve your issue.


      1. Yeah bro, that file was corrupted. Anyhow I installed pac rom successfully. but this is soo damn slow 🙁

        What’s up with that? I like this, but cant live with this lag

        1. Hi Lakzhika.

          You mean the OS is slow? I can’t believe that! Can you provide me the screenshot of your “Currently Running Apps” page from settings? Let me check your RAM usage first.


          1. Here it is,


            SJB 8.0 worked fine on this phone without any lag issues

          2. Hi Lakzhika.

            You are using some high resource consumption apps. Try to use optimized apps. Optimized apps will not stay background. I’m not having any issues with performance. Try to kill apps that are running on background.


          3. but I had those apps in SJB too without any problem. Should I re-flash the kitkat? 🙁

          4. Hi Lakhiya.

            Really sad news for me. Anyway, If you are not satisfied you can revert the update. My suggestion is to wait for the next update.


  19. Dear Akhil K A,

    I am proud of you first. I am also having Xperia Ray from past two years . struck with ICS and finaly find your website. its totally aw some . i loaded my xperia with SJB. Now i find PAC KK in your website. clarify me , how is the battery life, speed, between SJB and PAC KK.

    1. Hello Arif.

      Thank you so much for your valuable comment. I’m very satisfied with the Battery backup. I’m getting 24-48hrs of battery backup for normal usage!


  20. thanks akhil!!!
    poweramp was much satisfied, but it’s a trail pack.
    what can I do?
    how to get pro version?

    1. Hello Yogarajan.

      Thanks for the update. That exclusive article will be published on next week. Kindly wait for that article 🙂


  21. I tried to update to kitkat from GB directly. but when I flashed the kernal using above .img file, phone hangs up at PacMan logo

    What’s wrong?

    1. Hi Lakzhika.

    Thanks again!

    1. Hi Akhil,

      It worked flawlessly as usual.

      But, I cannot figure out how to make the main workspace a single workspace. I don’t like swiping from left to right.

      Haha, in any case, I’ll play around with it some more.


    2. Hi Asche.

      Please follow this article:

      Just follow “Step 1: Bootloader Unlocking”. This will unlock your bootloader.


  30. hai akhil
    my poweramp is going to expired,so plz give the solution.

    sorry for the disturbance.

    1. Oh Sorry! I forgot:(

      Please wait. I will publish the article as soon as possible.


  31. Dear Akhil….

    Can you give me a solution ???


    1. Hi Akhil,

      What is the use of “terminal emulator” which was installed in my xperia ray.
      Anything editable with that…???


      1. Hi Graspy.

        It is for advanced users for testing, running and debugging. You can disable it via “apps” in the settings.


  32. Dear Akhil,
    I have some doubts
    1.How to delete a widget or application icons from home screen?In old ICS there was an option to drag and drop it in the ‘trash can’.
    2.SD card is not detected by computer when connected through micro USB cable.So what to do to transfer files from/to the computer.
    3.Can we delete the whole contents of the SD card without affecting the operation of the phone or do we have to keep some files/folders that are essential for the operation of the phone.
    finally waiting for your article about’ bloatware removal’.

    1. Hi.

      1. Long click on widget and drag it to the top of the screen. You can see “X Remove” on top. Just drag and drop your widget to that section.

      2. Download and install “Usb Mass Storage Enabler“. Then open the app and click on “Mass storage”. That’s all. Now connect your device to pc. After connecting, you can see a notification on notification bar on mass storage. Click on that notification and turn on usb mass storage mode!

      3.After connecting your device to pc in mass storage mode, you can manually delete those files/folders from your SD card.

      Hope this helps.

      Now I’m busy with my semester exam. Article will be published soon. Sorry!


  33. Android Version : 4.0.4
    Kernel Version :
    Build number : 4.1.B.0.587

    Can i install kitkat directly ?
    without rooted and unlocked boot-loader

    4.0.4 update by Sony PC Companion 2.1

    1. Rooting Status :
      Bootloader unlock allowed: yes

    2. Hi Sara.

      You can’t directly install KitKat on your xperia ray. To install a custom ROM, you have to unlock your device.

  34. :'( failed….. bootloader relocked… now how can i unlock it???

  35. invalid vendor id

  36. hay Akhil,,thanks for the articel,,i success install kitkat on my android, but I did not find the menu option Developer to enable usb debugging,, please help me

    1. Hi.

      Thanks for the query. You can turn on/off you usb debugging by going to: Settings>>Developer Options(4th option in System settings)>> check/uncheck Android debugging option!


  37. hAY

    after I install kitkat, android usb debugging on my android not detected in flashtoll, can you help me? thanks

    1. Hi.

      I’m not getting you. Can you please explain your issue?


      1. Hi Akhil,

        I am encountering the same issue as hary.

        When I plug my Xperia Ray to my laptop and open Flashtool (to try re-flashing and downgrade to Jellybean) its not being detected that my Xperia Ray is plugged in.

        So basically, we’re stuck with this as we are unable to re-flash our Rays?

        Although I like the way it feels, quite fast actually. And managed to resolve the low memory by partitioning my 4GB SD Card to 2.5GB and dedicating the rest (via Link2SD) to ext2 Phone Memory.

        I followed the guide below, might need to skip the first few parts:

  38. hai,
    camera was working fine ,but it gives clear pics only when i take close up shots.
    for long range shot it was not so good.
    what happen?
    (camera is only problem for all custom rom)

    1. Hi.

      This is the major issue on most of the Custom ROM. I hope, this will resolve on future updates!


      1. Probably not? It has been commented in forums that its not likely to be resolved by future updates. Apparently Sony has not released drivers for the cam or such. If you want cam to work better, there is no option but to stick to ICS. And its difficult to go back to Sony’s buggy and sluggish ICS after using these custom ROMs.

        This is really a huge disadvantage.

        1. That’s very disappointing.


  39. hi there

    i wanna ask what should i do if i accidentally flash my android before i paste the rom and gapps zip inside my smartphone?

    i previously used that sjb 8.0 rom..hope you can reply me asap..thanks

    1. Hi Akmal

      Just remove the SD card and copy the files to the SD card using a card reader.


  40. Thanks for the excellent guide!

    1. Thanks Dinho 🙂

  41. how much internal memory is occupied by this rom?

    1. Hi Dinesh.

      You will get more than 250MB free memory.


  42. Wifi is working properly?

    1. Hi Dinesh.

      WiFi is working fine.

  52. hai ., akhil , im fan for your jobs
    i have little problem here ,

    it said it was failed , so i try to repeat the process it like take forever to wait until my phone battery is drain , so do you have any solution here ? tq

    1. Hi Fie.

      Sorry for the late reply. Exams are going on 🙁

      This issue may occur due to corruption of zipped package or a hardware issue(ROM).

      Try this:

      1. Download the package one more time and try again.


      2. Try the whole step one more time.

      If these not worked, then the issue is with your ROM 🙁

      Then, you need to contact the nearest Sony service center.

      Hope this helps.


  53. Hi Akhil,

    Will you consider creating a guide for MIUI for Xperia Ray as well? It has very nice interface!

    Thank you!

    1. Hi Asche.

      Let me check 🙂


  54. Hi Akhil,

    I have my xperia ray 4.0.4 into kitkat 4.4.2. Its good working. nice job.


    1. Hi Ganganatha.

      Thank you for your feedback


      1. Hi Akhil,

        I have updated google camera from google play store, but some options are not shown on camera like “Lens Blur, Photo Sphare, Panorama and HDB+”. Tell me what is wrong???


        1. Hi.

          Did you tried any other camera apps? If not, give it a try.


  55. Hi Akhil,

    Hope you are doing well,

    1. Hi srikanth.

      Sorry for the late reply. You log looks fine. This is a minor issue. May be a restart or repeating the last step may resolve your issue.

      Note:You need to wait minimum 15min after flashing, before going to turn on the device.


  56. hai
    I successfully unlock the poweramp full version!!
    without spent any money!!


    1. Hey.

      I know, how you did that 🙂 By the way. Now I’m busy with my exams. I will post an article more about this.


  57. I was succesful install the pac kk..but it doesent have play store?help!!!

    1. Hello Roy.

      Are you sure? Play store is included in the gapps. Did you installed the gapps package completely without any errors?

  58. Hi thanks for uploading this guide. If something happen, are u going to be able to install the ISC on xperia with pc companion? Thank you

    1. Hi.

      If you don’t like this ROM, you can revert it to the original stock ROM by using emma and PC suite.


  59. Hey Akhil,

    after a long hard fight, i finally installed kitkat. Thank you very much!
    I am very stunnend by the new performence and the range of settings 🙂

    1. Hi Ben.

    1. Hi Brian.

      Sorry for the inconvenience you have faced. I have updated the link. Please check now. Thank you for notifying me.


  62. Too bad, KitKat is to slow for my phone.
    Downgraded back to Jelly Bean.
    I will look forward for better performance.

    1. Hi Rainer.

      Speed and performance may differ in different devices. Because, everyone are not using the same apps. Try to optimize apps.

      I hope, future updates will resolve the performance issues.


  63. hi,

    2. Hi Malith.

      What is your device model name? Is it ST18? Are you on ICS?


  64. Gr8 work dude. keep going

    1. Hi Mohamed.

      Thanks for the feedback 🙂

  65. Hi Akhil, now I’m doing the installation on my ray Kitkat, I want to ask if I can format after completion of my SD card and I will be partitioned my SD card into 3 parts: the first for SD storage, both for Link2SD, the third to increase the RAM, what do you think?
    if good, how composition is right for kertu partition my SD (4Gb, xperia ray micro SD)?

    1. Hi.

      I lost my 8GB SD card because of doing partition. So, my suggestion is to don’t partition your SD card.

  66. Hi, akhil..
    i am interested to root my xperia ray..
    can you tell me what is the size of rom files. as it is not mentioned here while downloading. i am using a slow connection, if the size is high i will download from somewhere else… plz reply..

    1. Hi Prem.

      Sorry for the late reply. Go the new download page: You can see the full file details there.

      Total file count:3
      Total Size: 256.6MB



    1. Hi Yogarajan.

      You are saying how did you unlocked the poweramp music player for free. This is called software theft and piracy. I’m completely against for these type of illegal methods. As an Android Developer, we need to respect the hard-work of the app developer and support him by purchasing the apps. I will publish a detailed article on purchasing google play apps easily without using a credit card.


  68. hai akhil, i am having 4.0.4 on my xperia ray.. do i hav to root for installing kitkat?? how can it be done?

  69. Hi

    There are no installation files on the provided link.

    1. Hi.

      Thanks for the notification. “copy” website sucks. They are very buggy. So, I moved my all files to an another file sharing service. Now all links works fine.


  70. its very slooooooooooooooooooooow akhil… help me. JB is bezt. very fast

    1. Hi.

  71. hello.

    It’s stuck at the logo.

    i tried using the sony pc companion and the update service with no luck.

    any sugestions?

    1. Hi.

      Can you please provide me the error code/screenshot?


  72. Links are down on KitKat 4.4.2 ROM Files

    1. Hi.

      Thanks for the notification. copy website sucks. They are very buggy. So, I moved my all files to an another file sharing service. Now all links works fine.


  73. After I flashbooted the device I pressed Reboot device into system as the instructions says here

    But it never moves from the Pac Rom image

  74. I successfully installed Kitkat in my Xperia Ray everything’s fine except that DropBox app can’t seem to access the internet but all the other apps can.

    1. Hi.

      I have installed dropbox and tested for you. Works fine for me. By the way, are you using the latest version of dropbox? Are you using any antivirus apps that having Firewall? If yes, try to disable your anti-virus and try again. Please check it and update me.


      1. It works now, I reinstalled the Dropbox app from the Play Store, it works perfectly now. Thanks, Awesome guide hope you can make more in the future Android updates.

        1. Hi.

          Glad to know that. Don’t forget to subscribe us for future post updates. After this busy schedule, I’m going to publish some exclusive articles:)


  75. is there any way to increase the internal memory of ray.i have read in a blog that by partioning ur sd card it is possible…can i do this? please help

    1. Hi Krishna.

      It may corrupt your drive. I won’t recommend that.


    2. I have partitioned my card and have been using app2sd for several months now. Haven’t experienced any corruption till date. Using a 8 GB Sandisk (class 4). Corruption or not, its impossible to use the Ray without doing this. The internal memory is so less, especially after installing this ROM, that I wouldn’t be able to even install the most minimal set of apps that I need. I’m not sure what kind of corruption is being referred to, but if its some permanent form of corruption, one can always claim warranty for the card. Buy a good card like Sandisk with 5 year warranty… or maybe a Transcend with Lifetime warranty (though I have no idea how they define “lifetime”). Strontium too has 5 year warranty now, I believe.

      However, I’m not very happy with this ROM. It works fast and smooth after rebooting. But just around 24 hrs (or less, depending on usage), the free/available RAM reduces so much that it starts lagging like hell and apps even start crashing. The stock ICS ROM used to go for 8 days (maybe even more, I’v not checked beyond that) without needing to reboot. So I find this KitKat ROM quite unstable. Its like its got a memory leak. Is anybody else experiencing this?

      The camera quality also seems to have degraded. Though after using Vignette, and playing the settings, there is some improvement, and you can enable auto flash.

      1. Hi.

        You have done a great research. You are right, this ROM is not a perfect. But, in the next stable release, all the issues will be resolved. So, wait for the next stable release of Sony Xperia Ray KitKat 🙂


  76. hello! i already install kitkat on my xperia ray.thank you very much.i have only problem with the battery its draining there a solution for it?
    also can is it possible to change to other custom rom?ex. viper , is it possible?thanks!

  79. Hi, I’m currently running android 4.4.2 using the xperialegacy rom on my xperia ray. The problem is I need to download and flash when there’s an update. Would u recommend PAC ROM compared to my current ROM. Does this support automatic update? Thanks

      Main issue of our device. Sony support says, just neglect it! But, heating problem causes board issues 🙁 It is happened to me 🙁

  88. Hi Akhil,
    I am using Sony ericsson xperia ray (st18i). And I am having a Problem of black screen whle answering a call and when i put my phone idle for sometime…Switching the power button 3 times fastly unlock the device.but still it’s a problem right. I googled and got many answers like hardware problem, software problem etc..can u help me on this? I am asking this because i am going to flash kitkat to my device ( currently running superjellybean custom rom).While flashing it’s risky and less probable for getting the recovery screen…i had hardly seen 2 or 3 times the logo of super jelly bean in these 6 or 8 months while restarting.So can u suggest another method for flashing. Help will be really appreciated .

    1. Hi Shoukath

      Finally, a new Sony Xperia Ray is going to dead! I’m also having this issue:

      This is a motherboard issue. As per the sony support, the only solution is replacing the motherboard! No other solutions.

      Sony Sucks!

  89. Hi,

    I have instaled this rom and everything was OK until I turn on bluetooth.
    When I turn on bluetooth the battery drain is increased (10% per hour).
    I tried too with new version PAC rom for Xperia Ray but it is the same.
    I would like to use this rom but with that draining I will go back to original rom.
    Is there any solutions?

    1. Hi.

      Next update is coming. Please be patient. This issue will be resolved.

  93. Hi,

    I’ve successfully installed the pacman on my xperya ray… very nice.

    I’ve just a question.

    the bluetooth mac address of my stock rom was
    20:54:76:XX:XX:XX (20:54:76 SonyMobi # Sony Mobile Communications AB)

    the pacman rom now has:
    00:18:31:XX:XX:XX (00:18:31 TexasIns # Texas Instruments)

    is there a way to reset the original one? whuld you check what’s your bluetooth mac address
    (just a note: the wifi mac-address is the same as the stock rom…)

    ( anyway useful thread this one 🙂 )

  94. hi!
    I just flashed the kernel and now my phone is stuck on a screen saying “PAC ROMS”. Please help me with it!

      Thanks for the feedback:)

  100. Hello, I have completed the installation successfully. Everything works fine, there is just one issue with “flight mode”. When going from flight mode to online, the phone does not connect to the GSM network (WiFi works). If I try to manually search for a network I just get an error message. It helps rebooting the phone. Is this a known issue, any solution? Thank you.

    1. Hi Sreelakshmi.

      Poweramp is a paid app and you need to purchase it after using the trail. Using illegal version is harmful to your device. If you are interested, I can help you to buy it.

    1. xperia keyboard (somebody did it [Ver. 6.3.A but eating my RAM & not getting fit to screen exactly as previous one,i think you can do some tweak with that.)
    2. Walkman ( i am able to install the version 7.15 in Ray but it also eating my RAM & its not working
    as default music app & not working as integrated one)
    3. xperia gallary.
    4. Facebook integration( atleast facebook contact sync with FB images).
    5. (not much important BUT i like simple but great boot animation like xperia original one)


    Before this ROM i am on
    1. wifi 24×7.
    2. at-least 2hrs talking in conferencewith 2-3 frnds,
    3. & whats app & FB for around 2 hrs.

    with all this, battery last for around 30-35 hrs,
    but now with same activities it last for only 12 hrs “MAX”

    plz help

    & thanking YOU A LOT again for this nit & nice “KITKAT” .

    Waiting eagerly. for any updates.

  113. Stuck on PAC rom loading screen.What to do now? 🙁

    1. Hi Afsal.

      All you need is to wait for some time to cool the motherboard.


      1. i am stuck on the PACROMS loading screen too. Waiting for about 15 minutes on on.

  114. First time I have tried this procedure with a phone and whilst its a bit of a head scratcher just got to read all the instructions carefully.

    Only problem I had was the flash tool would not download. Just downloaded it from

    Now went from Gingerbread to Kitkat on my experia ray

    Cheers dude

    1. Hello.

      Thank you for spending your valuable time for comment here. This is my only inspiration. New awesome and helpful tips and tricks for android device is coming. Hope you are following NetMascots!


  115. Thanks for this great work. I just spent a few hours installing KitKat my XPeria Ray which had run empty
    on internal space with the old Android 4.0.4 even through mostly everything had been moved to the SD card. At this point KitKat seems to work great with ~100 MB of internal storage free even though I have installed a few more apps installed than I had before 🙂 Had to replace the “Launcher3” app with another launcher though. After each reboot, some of my icons on the home screen disappeared.

    1. Hi.

      Thank you for spending your valuable time to comment here. I’m using Apex Launcher. It rocks on my device. Did you tried that?


  116. hi,
    its amazing.
    now i am using kitkat in my xperia ray only with the help of ur tutorial.
    awesome performance!!!!!

    thanks bro…

    i have some queries…

    can we use different rom???
    is it possible to switch earlier version???

    1. Hello Sameer.

      Thanks for the inspiring comment. You are free to use any rom by following the same method I have used it here. Only difference is with the Kernel and the ROMS 🙂


  117. Bro, I Have Flashed It… Everything is fine except for the home button…. Home button is not working help me out… (i tried using on screen buttons but that home is also not working)

    1. Hi Chethan.

      Looks like ROM issue. Did you tried factory reset? Try to install once again.No need to flash, just install the two zipped files.


  118. thanks for tutorial… work for me… good job…

    1. Hi Mulyadi.

      Thanks for reading my article and thank you so much spending your valuable time to comment here. I really appreciate it.

      I hope you visit again.

  119. hey did everything on my xperia ray, but I am stuck on the pac roms loading screen and I do not know why. please help!!!

    1. Hi Ethan.

      It is normal in some devices. Just turn off the device for 15min and restart it. Still not working? Please let me know.


      1. it is still not working… please help

        1. Hi Ethen.

          May be this may be kernel issue or ROM issue. I suggest you to repeat the whole step again and restart the phone after 20min at-least. If not worked, try to downgrade to jell bean 8.0


  120. Can you please help me on this?
    I do have a rooted Xperia Ray (st 18i) with me. It have some hardware problem (Black screen issue)
    so the screen is black while restarting as well as while unlocking.I have hardly seen the logo of xperia once or twice.So the method you described is not possible for me.Ray is installed with the latest ICS version as your prerequisities mentioned.So the option, I think, that is possible is, flashing my phone with a ftf file of the Kitkat custom rom.I searched much and couldn’t find any such file for kitkat.I have ftf file for jelly bean and I have tried it, it works.Can you please help me on this ?
    Is there any other option?

    1. Hi Shoukath.

      I’m also having this hardware issue. This is a motherboard issue. The only solution is replacement of the mother board. FTF file is not available for this ROM. My solution is, just wait minimum 30min to cool the board and turn on the phone while you performing each restart. This is what I’m doing. Try it!


  121. Hey there,

    works fine good Job 🙂

    but a small overclock would be nice 🙂 (1,4GHz)? Maybe possible?
    Was searching a lot for a OC Kernel.. just found some for ICS 🙁

    Thank you!

    1. Hi Martin.

      Thanks for the comment. Overclock makes the device unstable and heating issue. Not good for the motherboard.

  122. Thank you for this HOW TO. It works like a charm.

    1. Hi Rahasia

      Thanks for your valuable comment.

  123. Thanks works in one go…

    Only point which I noticed till now is that ‘Remove’ is not visible when you try to delete shortcut from home screen.

    1. Hi KD.

      That’s a good opinion. Thanks for your valuable comment.


  124. I can not run my device into recovery mode. Mine OS is ICS Official update.

    1. Hi.

      Did you tried the manual method (Pressing the volume key while booting) ?

  125. Hi, I upgraded to kitkat from jellybean. But found that battery life is really bad & wanted to downgrade back to jellybean. So, I flashed SuperFusionRay.img file as in “”. But I am not ale to enter into recovery mode. After superfusion logo, I get blank screen. Tried removing battery for 15 mins. But still not working. Can you pls help?

    1. Hi.

      Did you flash the jelly bean kernel? If not, flash it again and WAIT 20Min, and then install the 2 zipped files (ROM and gapps).


      1. Yes. That was the mistake. I restored original rom. Upgraded to 4.0.4, rooted & then reinstalled 4.1.2. Thanks

  126. I can not download boot.img file from that folder u shared. I tried to download all three files at once but the problem boot.img show corrupt. Please re-upload or suggest a solution.

    1. Hi Asiful.

      Sorry for the inconvenience caused. I have uploaded all the files to another hosting website. Now all links are working fine.


  127. Hi Akhil
    I’m using ray and android version 2.3.4, and you in one of your answers admitted i can directly update it to kitkat now i have a guestion: i’m from iran and do you think i would have some problem , you know because of sanction 🙁
    i really appreciate it

    1. Hello Roni.

      No problem. Go through it. But, kitkat is now having some bugs (Not major). Why don’t you try jelly bean. Just do a try, and wait for the next release of KitKat. This is just my opinion. What do you think?


  128. All work fine, thanks a lot!!

  129. .I have a little problem sir .but it’s not about kitkat on my ray .sorry

  130. Hi
    The method worked flawlessly, got a kitkat running now. Except, big problem 🙁 the battery wont charge at all. It says charging when plugged in, but i see i the percentage going down steadily even though its plugged in. The indicator is now red color, last 12% left. Help! 🙁

  154. Hello Akhil,
    The upgrade went smooth. Thanks!
    I also had a battery drain, but I followed the procedure for the Xperia Z on Kitkat. Now I can do three days again without recharging.
    The only thing I’m missing is a (Dutch) dictionary in the SMS app. It only proposes from the contacts list now.
    Do you know a way to do this?

    1. Hello Akhil / All,

      I installed “User dictionary Manager”. It allows to easily import/clean up into the personal dictionary. It’s not perfect, but it does the job.


  155. Hi! I successfully installed the ROM, however upon switching on the phone it was stuck to the PACROMS logo. I pulled the battery and waited for another 15-20 mins, nothing happened. Please help.

  156. What recovery app to use?
    I have already rooted but it is uncompatible with the phone
    Does it really need to use the 4.1.a kernel?

    Does it really need to use the 4.1.a kernel?

    1. Hi.

      Did you completed the gapps installation without errors?

  165. This is really great, thank you!! 🙂

    1. Thanks for your comment!

  166. Hello Akhil,

    Thank you for this detailed, step-by-step, tutorial. 🙂 I was able to successfully use this ROM on my Xperia Ray ST18i.

    I’ve been using this for over a month now. But just recently, I have started missing the “feel” of Ray’s stock ROM, w/c is GB. And now, I wish to downgrade to GB. So I searched and found this tutorial of yours:

    Does this method work if I downgrade from this ROM (PACROM) back to GB stock ROM? And also, do you have/know of a custom GB ROM which has no bloatwares and bug-free,? (I just want the stability of the stock GB ROM but minus the bloatwares that comes with it.)

    If possible, please advice.

    Kind Regards,

    1. Hi.

      ICS is more stable and optimized than GB!

  167. Does anyone have any experience with never releases of KitKat from PAC ROMS? I’m reluctant to install them but I’m having some annoying SMS sending issues that I’d like to see fixed.

  168. not getting this level in succcess fuly….. sir

    1. Hi.

      Kindly explain.

  169. Whilst trying to install the zip file pac_uru… I have got E: error in /storage/sdcard0/pac_uru… (status 0) followed by installation aborted. I have tried this several times with the same result. My phone is now useless. Any help appreciated.

    1. Hi.

      Try to wipe data and wipe cache.

      1. I am so late but I am sure that your default apps installation location is memory card. Because update check firstly the hardware requirement, though you download correct rom but your default apps installation does not satisfy the criterion so the first abort status( status 0) is showing.

        1. Hi Chinmoy!

          Please explain your issue clearly. I’m happy to help you!

  170. Hi Akhil i’m trying to rooting my xperia ray ics to kitkat for a past few days i’m having all files that you asked to download but the problem is that when i m trying to do fastboot or unlocking the bootloader as you mention, my device also shown the blue light but in my pc there is no response at all. Also i m try to get response in command window it shows for time.Please help me.

    1. Hi.

      Did you tried One Click Root software for xperia ray? I have published an article!

  171. Hi Akhil.
    Why I can’t install the flashtool through this link:
    When I try to download, it shows this:
    “HTTP/1.1 503 Service Temporarily Unavailable”

    1. Hi.

      That is temporary error. That is fixed and the site is working fine.


  172. my ray is not rooted.

  174. How to install cwm or higher on xperia ray

    1. Hi.

      Sorry for the late reply. Procedures are same. You can follow this post instructions.

  175. Hi Akhil,

    Thank you for the software and i have sucesfully installed it but there is problem am facing. I am unable to receive calls. when anyone calls me it automatically cuts the call . Can you help me in this issue.


    1. Hi.

      Did you followed the steps correctly? If yes, try a factory reset.

  176. Hi Akhil,

    Thanks for sharing. I have successfully updated my ROM, waited 15 mins to start again. Now I’m stuck at PAC ROMS loading screen for over 30 minutes now. Do I need to wait more or are we missing out something. If wait, what cut off should I keep in mind?

    Arya A.

    1. Hi.

      This is happening because of board temperature raising.

      So, just turn off the device and turn on after sometime.


  177. I installed Kitkat 4.4 as per your instructions. everything works pretty well, in fact awesome.
    I love the interface.
    Thanks for doing such good work. Hope you will be Developer in sony inc.

    But the problem i faced with kitkat 4.4 is that, I cannot use my mobile data, even after doing all accesspoint settings , the mobile don’t seem to use Gprs or 3g or H , as i don’t see the logo near the network bar, and no mobile data access.
    Can u suggest me a solution?

    1. Hi Ajay.

      Welcome to NetMascots,a and thanks for your compliments.

      In my phone, it is working fine. Did you tried factory reset? Because, some of the users fixed these type of issue by resetting the device.


      1. Same problem here. What implies a factory reset? Loosing all data & apps? Loosing kitkat-ROM and start over again? How do I do a factory reset?

        1. Hi.

          Go to settings and storage options, to restore your phone. Restoring will erase your all apps and app date from your device.


  178. Hello Akhil,
    I root my phone but when I reboot it recovery mode it just restart could found the further process.
    please give me advice if you can.

    1. Hi.

      Did you unlocked your boot loader?

  179. Seems to work very good, except… internet 3G bugs, internet worked fine on android 4.0.4, but on kitkat I seem to have hardly any internet connection. Sometimes it works, most of the time it does not!
    Any ideas?

    And I miss my FM radio!


    1. Actually I do see all logos (3G & H), whattapp seems to work most of the time, gmail and playstore only some of the times. Which proofs that login/password is ok.. But network connection is extremely unstable (95% off!)

  180. My Phone is starting Rom but it loads and loads since 20 min to get to the settup.Please help.

  181. So far so good, custom 3G settings did the trick. But:
    – FM radio not available and Spirit 1 (= FM radio) app does not function
    – GPS also does not function. Tried different GPS-apps, they all keep searching for signal
    – Minor problem: Wifi enabled crashes phone (remove battery necessary)
    Can you help out?

  205. my xperia ray is running on ICS 4.0.4 and to update to kitkat do i have to install clockworkmode just like in the jellybean installation tutorial.

  206. Hi Akhil

    i’m stuck with the bootloader unlocking, whenever i try it says “waiting for the device”. can you help me with this.

  207. hey akhil
    there are some bugs
    1. network has a problem
    2. how can i put system apps to sd card

  208. Hi,
    does the custom ROM have also other languages than English included i.e. German or French?

  209. i have a question i have rooted my xperia ray st18i and i have unlocked the bootloader, am i able to go to bootloader or recovery mode without procceing any thing else? if yes how?

  210. Hi
    Thank you for a fantastic instruction – really enjoying my ray with 4.4.2 android.
    To be picky I would like to install the old sony camera app which took better photos and was quicker.

    Anyway after a couple of weeks of usage I just realized that WIFI tethering does not function. This really is bad news for me 🙁
    I am hoping that someone has a solution.

    When I turn it on you can connect your computer and surf but then after 5-60 seconds the WIFI signal just dissapears (the quicker if you surf around heavily). Then when you turn off and then on the wifi sharing the phone crashes and reboots.

    I am not sure how to find fault codes so I do not know what the fault is.
    I installed barnacle wifi tether and it says “unable to open ./wifi no such file or directory
    Could this be it? where do I find a complete /wifi ?

    thanks for any feedback

  211. Pac console has stopped, Blame The Split Screen ….. ???

    Wechat has stopped, Blame The Split Screen ….. ???

    Almost everything has stopped ……

  212. Dear bro,tnx for helping us……………

    For Windows users, when asked for a driver, point to the usb_driver folder where you placed the android_winusb.inf-file, and select the Android Boot loader Interface-file……..

    i’m stuck on this….i mean my computer dont ask me for a driver.i tried to manually bootloader but then it say’s waiting for device….. plzzz help me out….. my model is xperia ray st1a……
    Tnx in advance

  213. It does work (althought it is still very complicated and not recommended for beginners at all).

    4.4.2. is pretty on my xperia ray but most definitely a lot slower AND a lot, lot more unstable. Settings>Apps gives me a 50% chance of crash.

    Booting takes decades and the animation is terrible, but ok.

    I wonder why it is so mich slower than 4.0…

    Anyway, ok guide, managed it with the help of a few other sites.

  214. Dear bro,
    i’m stuck on bootloader unlocking…..after the blue light comes on my computer dont ask me for driver selection….even i want to search driver manually there is no driver at all…..but when i turn on the phone i see the driver…..plzzzz help me…….if i need driver then plzzz give me the url of it….
    i’m really counting on u brother.

  215. Hi!
    I had rooted my ST18i and unblocked the bootloader. It was running ICS. I wanted to flash it to KitKat but couldn’t find the flash tool you used in this tutorial. So I used Emma, the Sony flash tool. I copied the Kitkat for Sony Xperia file + the Google file to the SD card with mass storage mode. Then I went and flashed with Emma, and now my phone is flashed back to 2.3!
    It looks unrooted and I have no idea what to do. There is no superuser app and I’m not even sure whether the bootloader is still unlocked.
    I wanted to run Kitkat and get a second partition. Please help!

  216. Hi Akhil,

    I’m still facing a problem while trying to install this ROM on my phone.

    This is the output I get from Flashtool:

    Here’s the thing though, I have rooted my phone. I followed the steps on rooting, and it worked successfully (I even have the SuperUser app installed after the rooting process, and I’ve cross-checked with Root Checker Basic just to be sure)

    Here are a few more details for you:

  231. Greetings
    I followed the instructions and installed on my ray, with no problems, but when I go into google play store it crashes alot.

    I have allready tried reinstalling the Gapps package, but with no help.
    Have you tried this or heard of it?

    Best regards

  232. Hello Akhil,

    thanks a lot for the great work and the very helpful tutorial!!!

    KK 4.4.2 works very well on my ray! But there seems to be some bugs. Sometimes I get no network. Sometimes there are problems with sms. Sometimes problem with battery.
    My question:
    Is it possible to use a later ROM version from PAC ROMS for the Ray, e.g. “” or at least “” ?

    Ones again thanks a lot and keep up the great work!

  233. Just a big thank you! I tried to install legacy version of kitkat and failed miserably for a week. Then I remembered seeing your post in the google listings. 1 day later my wife’s old Ray has been updated and I can now pair it with android wear and use it for running with!

    Again thank you!

    1. Thank you for your appreciation James. It means a lot to me 🙂

  235. akhil bro i have followed all steps but after step advanced>>power off my phone won’t turn on

  236. Hi Akhil,

    When I checked the screenshots you posted I noticed that your phone got 470MB internal memory and mine has 420MB only. Will this update eat up a lot of my phone’s internal memory? I’m wondering if I will still be able to install Facebook and FB Messenger since they eat up a lot of megs. Or will it be better for my phone?

    Thanks a lot. You’ve been very helpful.
