  1. What about the major issues that exist in SJB 8, like compass shimmering in Gmaps and no way to even toggle flash in camera app, etc? Do they exist in this ROM?

    1. Hi (What is your name?)

      Thanks for your query. All the issues of Jelly Bean is resolved in the KitKat 4.4.2 ROM.

      1. Compass is working fine [Tested]
      2. Flash can be toggled[Tested]
      3. Video can be paused while recording[Tested]

  2. Great. Should try it out soon. Google Maps and navigation was almost unusable in SJB8 because of the compass causing the screen to shake.

    How is the battery life on the Kit Kat ROM? Another issue with SJB8 was that the phone would keep waking up when it should be sleeping. Even the WiFI would keep waking up very frequently (I seldom use mobile data) despite setting it to time in the WiFi policy. Really hope this dosen’t happen in the Kitkat ROM.

    1. Hi.

      The battery is getting good backup time. Wifi issue is also resolved in this ROM [Tested].


  3. .sorry sir ,but why every time I click on complete revew articles there’s no images .just blank ?

  4. Hi,
    Did camera working well in this because i want Good camera (picture) quality with gadget i have (xperia ray)
    and Is this rom have bravia engin for sony ? If no then please provide

    1. Hi.

      Camera works fine on this version. Sony bravia engine is enabled in this version. But, you can’t disable that. So, there is no settings provided.


  5. Dear Akhil,
    My phone battery will not charge,from USB port or normal charger when the phone is ON,but will start charging when it is turned OFF and thereafter it will charge as normal when it is turned ON.One more doubt how to delete a widget or application icons from home screen?In old ICS there was a delete option to drag and drop it in the ‘trash’.

    1. Hi Joy.

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


      1. Dear Akhil,
        When the phone is ON and if we connect the charger to AC mains it will not charge,and if we connect the Micro USB cable to laptop USB port the battery notification will indicate charging, but actually battery will be discharging.If we switch off the phone and connect to AC mains or USB port it will start charging ,so every time I have to switch off the mobile to get the battery charged, once it start charging we can switch on the mobile and it will continue charging.

        1. Hi.

          This is a hardware issue (May be on-board issue). Take your phone to nearest sony service centre.


          1. I found out the problem : Its a bug caused when the USB debugging is disabled . Enable it and you wil have no problem charging the phone 🙂

        2. ya same problem for me also, it started after 10 days. how to solve this charging problem.

          1. Hi.

            Next update is coming. Please be patient.


        3. Try factory reseting

        4. Same here . Started a day after using PACKMAN rom . Its irritating because neither the phone gets charged or is detected by PC for media transfer :/

  6. Hi Boss….

    I installed PACMAN kitkat custom ROM in my Xperia Ray. In that Rom, Radio application is not available.
    How can i install radio app.????

    Can you give me a solution for this problem….??

    I am waiting…..

      1. Hi Akhil,

        Thanks for your reply boss.
        i tried that. But that application is online radio…
        Can you gave offline radio…???

        Thanks and regards,

        1. Hi Grasphy.

          Let me check. Kindly give me some time. I will update you as soon as possible.


          1. ok Boss.

            Take your time…


          2. You are always welcome.


  7. Finally installed this ROM. Was previously using SJB8, so here are some observations:

    Compass seems to be working ok, like you said. Was a serious problem on SJB8

    Flash can be toggled in the camera app. But no auto flash. But at least better than no flash at all on SJB8. It was possible to have auto flash within Vignette in the stock ICS ROM. Hope it works on this ROM (yet to try). Others who want auto flash can try Vignette and please report here if it works. It is one of the best camera apps I’v used.

    Phone seems to sleep better on this ROM. Was an issue on SJB8, where it used to keep waking intermittently. WiFI waking was also an issue. Both used to affect battery.

    The Pacman KitKat ROM has some irritations also –

    The battery percentage font in the status bar as as ugly as it can get. The font does not match with the font used for time, etc. And there does not seem to be any way to change colors of the fonts.

    Not absolutely sure yet, as its been a very short time since I’v started using it, but battery still seems to disappoint. Have changed the Governor, I/O scheduler to SmartassV2, noop. Seems to be better for the battery, but will reserve final comments until I’v used it for a few days.

    Streaming video experience in the stock browser on SJ8 was much better. On this KitKat ROM its somehow not that good. Browser crashes sometimes, and often the video itself does not even begin to play. This may be possibly because of more free RAM on SJB8.

    Overall SJB8 seemed a tad smoother/fluid than this KitKat ROM. However, due to the serious bugs in compass, camera app crashing, no way to turn on flash in camera app, etc., SJB8 was not a viable option for me. With that in mind, this KitKat ROM seems to be quite a viable option.

    1. Hi (What is your name?).

      Thank you for your valuable feedback and truthful review. I really appreciate your helping mentality. By, the way, let me try “Vignette” app on xperia ray.

      I will consider your review in future custom ROM tutorials.

      Thanks again.

  8. hi guys this is great my xperia is very fast but i have some bug for fixed ” I Can’t trun on flash light on Reccording The Video ” is very dificult when im record in the dark
    Please Help me To Resolve this bugs

    1. Hi Thomi.

      It is working fine for me. It may be your hardware issue or you are doing something wrong.

      Just turn on the camera. Then go to video mode. Then click on the options in the display. Click on the “Thunder” button. Turn on the flash.


  9. Hi Akhil,

    I updated my phone 10 days ago following your instructions. I am very happy with the result. The ROM is very smooth and I love all the extra features.
    Concerning your instructions there are two points where I got lost:
    1) I had an error in the flash manager, requesting missing drivers
    2) you did not mention bootlader unlocking. Is probably obvious, but took me some time to figure out.
    Other then those two hickups – easily solved with google – no issues.

    Thanks a lot !

    1. Hello Jaap.

      Sorry for the late reply. University exams going on!

      Anyway, thanks for the feedback. Did you tried “ES File explorer” ? I’m using that! Have a try. It is awesome.


  10. Wifi issue with this ROM. Give any solution

    1. Hi Dinesh.

      Working fine for me. Looks like this is a minor issue with your configuration. Can you explain the issue?

    1. Hi Ikhwan.

      This completely depends on the other apps you are running on your xperia ray. Can you give me you app list currently installed and using?

  13. hI AKHIL

    3> in some comment i read about radio, Is it missing this ROM

    can you please change the booting screen and animation to some brillient colors this red.

    1. Hi Zibran.

      Sorry for the late reply. I’m on some customizations. You may see some attractive boot animation in the future updates:)


  14. sorry i missed this one Is Home Srceen is rotable to any side i like landscape even if browsing through screens

    1. Hi Zibran.

      Because of some limitation in hardware, It is really hard to do that 🙁


  15. hi your link to file download is not active or broken i cant download it.
    please share alternate link for the same

    Thanks in adv

    1. Hi Zibran.

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


  16. hi Akhil,
    I want to thank you and ask, after successfully upgrading to kitkat, I want to partition my SD card (original Sony 4gb SD = 3.6 gb estate), how the composition / ratio of the size of each partition (partition 3), in The second partition if I had to choose ext2 or fat32? whether the linux swap partition 3 to actually increase the RAM capacity?

    1. Hi Dhany.

      I’m totally against for manual partitioning. This will definitely badly affect your motherboard and performance.


  17. Dear Sir,
    I am newbies in this. May I ask, if I install this ROM, will I still get the front light notification for any incoming SMS or miss called like stock GB rom? Thank you.

  18. Hi Akhil. In this ROM bluetooth will work or not? Thanks!!!

    1. Hi.

      Bluetooth is working fine:)


  19. always get an error while using Screenshot below

    1. Hi Upendra.

      Try Apex Launcher. It is awesome.


  20. Thank you Bro for your instructions and links…. I finally installed Kitkat on my Xperia ray… But the problem is that home button is not working….. Any help please…

  21. Hi Akhil,

    First BIG thanks for your post and establishing/maintaining I’m loving your posts as it’s most helpful to me at-least.

    Coming to latest android version on my xperia ray mobile, this new installation kitkat 4.4.2 looks awesome to me, with minor issues.
    It’s much faster and customizable. Best thing I can’t see any extra/unwanted apps in this installation as earlier installations had. Like Facebook, twitter, radio, etc.

    But I feel bad when it hanged 2 times in 2 days. Also only a very few times, I responds damn slow, otherwise I’m damn happy with it’s performance.

    Please suggest me on followings:
    -How can I hide transparent google search bar on wallpaper?
    -How can I see AM/PM with time on top-right?
    -Which apps I can move to SD card, or what should I do to increase free size of ROM as well as RAM?
    -Or any other app (like should I use to get more free ram?
    -Should I update any configuration (e.g. I/O scheduling, CPU scheduling) to increase free momory and performance?
    -Can I update it’s boot animation to look it better, as I seriously hate such animation. Can you please suggest me if I should follow or not? What should be the very first line in file desc.txt? e.g. “480 854 20”
