Install AOKP KangXperia JB ROM Port on SONY Xperia T

Sony Xperia T has been released and it already got an ‘how-to root’ guide, which means that now you can easily install custom ROMs. The stock ROM that comes with Xperia T is the Android 4.0 ICS and this guide will help you flash an unofficial AOKP Jelly Bean-based port firmware. Read the entire tutorial and only when you’re sure that you want this ROM, you should begin the update.

This ROM is not an official Sony release and it is mainly a port firmware that could possibly be packing some errors and bugs. If you find any errors, then you should post them in our comments field. Note that this update is pure stock and it doesn’t contain any bloatware which means that some application will be totally different from the original Android ones.

In order to make sure that you will not lose any important files, please read the preparation guide below:

  • Install this custom ROM only on the Sony Xperia T model. Do not attempt to install it on any other devices, as that might make the device unusable and you won’t be able to use it anymore. If your device is a Sony Xperia T then you can continue with the rest of this tutorial.
  • The Xperia T phone has to be on an unlocked bootloader, it has to be rooted and running a custom Recovery image. So, in case your device doesn’t meet these requirements, then you should first unlock its bootloader, then root and install CWM Recovery. After that you can return to this article.
  • Move all the important files on the phone’s internal SD card. Alternatively, you can move the files on your computer and after the update is complete you can restore them.
  • Use the CWM Recovery to create a full backup of the existing ROM. This backup will be helpful in case you don’t like the new ROM.
  • Applications, SMS, Call Logs and the APN Internet Settings can be easily backed up using the following tools: SMS backup & restore | Call Logs backup & restore | APN Settings Backup & Restore | AppBack for Android. Note that some of these apps will work only with rooted phones.
  • In order not to lose important phone numbers and contacts details, use this guide HERE and learn how to sync them with your Gmail account.
  • Enable USB debugging option from your device’s development menu.
  • Your computer should feature the ADB software. Without ADB you will not be able to push the commands and the ROM on your device.
  • This tutorial is destined to be used by advanced Android users, as we will not be held responsible in case you damage your smartphone in the process. Also, do not skip any steps that I have listed in the tutorial, as that will result in a failed update attempt.
  • Charge your device’s battery before installing the new ROM. This will prevent the device from powering off while you’re flashing the new update.
  • Disable all antivirus software from your computer.

These are all the guidelines that you had to read before moving to the tutorial guide. In case you cannot complete the update, please ask for more help in our comments section and should come up with a solution.

How to install AOKP KangXperia Jelly Bean custom ROM on your Sony Xperia T:

  1. Download the custom ROM zip from HERE.
  2. Download the Gapps zip file from HERE.This file will allow you to install the Gtalk, Play store, Gmail and all other Google-based apps.
  3. Connect your Xperia T to your PC and then copy both ROM and Gapps zips on its internal SD card. Don’t extract the zip archives. NOTE: Leave the original files on your computer’s desktop screen.
  4. Download ‘fastboot’ file from HERE. Save the file on your PC and extract its contents into a single folder on your desktop. You should name it ‘FASTBOOT’ and there should be 4 files. This will help you flash the kernel required to run this new custom ROM. Remember that this can be applied only if you have ADB on your PC.
  5. Next, open the AOKP kangXperia ROM zip and extract the ‘boot.img’ file. Boot img file should now be placed in the ‘Fastboot’ folder. Now you should have 5 files in this directory.
  6. Put your device into ‘Fastboot mode’. Do it by pressing and holding pressed at the same time the ‘volume up’ key and while you’re doing this you should connect the Xperia T with your PC using the USB cable. Please note that the fastboot mode is entered when the ‘LED light’ on the phone is lit up.
  7. Go back to your PC and then press ‘SHIFT’ key and at the same time right-click on the white space of the ‘FASTBOOT’ folder. Select ‘open command window here’ and then the Command Prompt window will load. You need to flash the kernel. Note that this will work if you have Administrator rights.
  8. In Command Prompt window enter the following line:
    • fastboot flash boot boot.img     —- In case you see the ‘waiting for device’ alert or there it seems like nothing happens, then you should enter this command line: fastboot -i 0x0fce flash boot boot.img
  9. After the kernel is flashed you should see the ‘finished’ alert. Now you need to type ‘fastboot reboot’ in cmd window and then the device will restart. After the restart is complete and you see the LED lighting up purple, you need to press the ‘volume up’ button on your device. Now it will enter into CWM Recovery mode.
  10. Select ‘wipe data/ factory reset’ and confirm the action. Note that this step will not delete the contents stored on your phone’s internal sdcard.
  11. Now select ‘install zip from sdcard’ and after that select ‘choose zip from sdcard’. Find the ROM zip and install it.
  12. After the AOKP port ROM has been installed, you need to select again ‘choose zip from sdcard’ and install the Gapps zip file.
  13. When the ROM and the Gapps files have been installed, you should return to the main recovery screen.
  14. Select ‘Reboot system now’ and wait for the first boot process into AOKP csutom ROM completes. It shouldn’t take longer than 5 minutes.
  15. After the first boot is complete, your smartphone should show the new AOKP JB welcoming screen.
  16. Enter your Google Account credentials and take full control over your device.

NOTE: In case your device isn’t capable of booting or in case the first boot process takes over 15 minutes to complete, then something went wrong and the update wasn’t applied. Power off completely your device and then repeat the entire tutorial guide listed above. Eventually you should be able to flash this new custom ROM.

I hope that you found this guide helpful and that you’ve managed to successfully update its ROM.

In case you don’t like this new ROM, then you should use the backup you’ve created before starting the update and restore your smartphone to a working state.
