Jelly Bean based AOKP for Sony Xperia T


The Sony Xperia T might be a newly released device, but it still came with Android 4.0 out of the box instead of Android 4.1. However, you can update unofficial to Android 4.1 Jelly Bean thanks to AOKP ROM, which has already been ported to the device. Along with all the cool features of Jelly Bean, AOKP ROM features a lot of customization options as well as fast performance, along with a pure unadulterated Android look with no bloatware.

Keep in mind that this is not an official Sony ROM. It is a custom ROM under development and may have a few issues in it. Also, it is based on stock Android, so any Sony-specific features will not be available and a few apps will be different from their original versions (such as the camera or gallery).

Let’s take a look at how AOKP ROM can be installed on the Xperia T.


This ROM and the guide below are compatible only and only with the Sony Xperia T. It’s not compatible with any other device and may render an incompatible device unusable. Check your device model in Settings » About phone.


The methods and procedures discussed here are considered risky and you should not attempt anything if you don’t know completely what it is. If any damage occurs to your device, we won’t be held liable.

How to Install AOKP ROM on Sony Xperia T


  1. This procedure requires you to unlock the bootloader which will wipe all your apps, data and settings (but it will NOT touch your SD cards, so don’t worry about those). Backup your Apps and important data — bookmarks, contacts, SMS, APNs (internet settings), etc. This Android backup guide would help you.
    NOTE: Don’t forget to at least note down your network’s APN settings, which are required to make mobile data work. Go into Settings » More » Mobile Networks, click on the APN that is in use, then note down the setting for each field. While APN settings should be automatically restored from network, you can enter them manually if needed to make mobile data work. You can also find your APN details → here.
  2. Important! Your Xperia T must have an unlocked bootloader. You can unlock your bootloader officially → here. Unlocking bootloader voids your warranty, so make sure you have no problems with that before proceeding. Skip this step if you have already unlocked your phone’s bootloader.
  3. Download the ROM from its download page.
  4. Download the Google Apps package. This will install apps like Play Store, Gmail, etc. which are not present in the ROM by default.
    Download Gapps  |  Filename:
  5. Copy the two files downloaded in step 3 and 4 to the phone’s internal storage (DO NOT extract the files).
  6. Install ADB on your computer using the guide → here. This is required to flash the requisite kernel on your phone. (Skip if you already have ADB installed on your PC).
  7. Download fastboot, which will be used to flash the necessary kernel.
    Download Link  |  Filename:
  8. Extract the file to the C:\ drive on your computer to get a folder named Fastboot with four files inside it.
  9. Now, open the ROM’s zip file downloaded in step 3 and extract the boot.img file from inside. Copy this extracted boot.img file to the Fastboot folder in drive C, which will now have a total of 5 files inside it including boot.img.
  10. Now we need to flash the kernel (the boot.img file extracted in step 9). For that we need to connect your phone to the computer in fastboot mode. To do this, first plug the USB cable to PC, then pick up your phone and hold the Volume Up key, and then, while holding the Volume Up key, connect the USB cable to your phone.
    Note that the screen will remain blank in fastboot mode, only the LED on the phone will be lit up to indicate the phone is in fastboot mode.
  11. On the computer, click on Start menu » All Programs » Accessories » right-click on Command Prompt and click on Run as administrator.
  12. Now, in Command Prompt, type the following commands to flash the kernel , pressing Enter after each command.
    1. cd c:\Fastboot
    2. fastboot flash boot boot.img
      NOTE: If you get a “waiting for device” message with the above command or nothing happens, type fastboot -i 0x0fce flash boot boot.img to flash the kernel.
  13. Once the kernel flash is complete, you will get a “finished”/OKAY message in the command prompt window.
  14. [Read this step fully before performing it] Now, type fastboot reboot in the command prompt window to reboot the phone. Once the phone reboots and the LED light on the phone turns purple, start pressing the Volume up key (don’t hold it down, press it multiple times) to enter ClockworkMod recovery.
    In recovery, use Volume buttons to navigate and Home/Power button to select options.
  15. Select wipe data/factory reset, then select Yes on next screen to confirm. Wait a while till the data wipe is complete (this will NOT delete your personal files on the SD cards).
  16. Select install zip from sdcard, then select choose zip from sdcard. Scroll to the ROM file and select it. Confirm installation by selecting Yes on the next screen. The ROM will start installing.
  17. After ROM installation completes, select choose zip from sdcard again, then select the file to install the Google apps package.
  18. After the installation of the gapps package is complete, go back to the main recovery menu by selecting go back. Then, select reboot system now to reboot the phone into AOKP ROM. The first boot can take up to 5 minutes.

AOKP ROM, based on Android 4.1.1 Jelly Bean is now installed on your Xperia T. Visit the source page for more info and to get the latest updates on the ROM. Share your thoughts on the ROM in the comments.
