Install Leaked Android 4.1.2 Jelly Bean ROM On Sony Xperia S

The Xperia S was Sony’s flagship device in its NXT series and while one would have expected Jelly Bean to have hit the device way back, it’s still been a seemingly endless wait so far. However, there’s finally some good news in this regard, albeit not from Sony itself. You can now install the leaked 6.2.B.0.68 Android 4.1.2 Jelly Bean firmware on your Sony Xperia S, thanks to XDA Recognized Developer DoomLoRD. While this firmware was originally meant for developer (brown) devices, DoomLoRD was able to successfully modify it to boot on productions devices. However, being a leak, you shouldn’t expect everything to work flawlessly. If you still wish to given it a shot, you can install it right away.


As mentioned earlier, this build is primarily meant for development purposes to offer developers a way to test their works for Jelly Bean on the device before it’s officially released. This build is pre-rooted with busybox installed, but the kernel that it comes bundled with does not contain a custom recovery. The device will be able to detect GSM/HSPDA networks, but will not be able to connect to them so yes, the phone function is broken for now, so install it only if you just want to temporarily get a taste of the official Jelly Bean ROM running on your phone.

Disclaimer: Please follow this guide at your own risk. AddictiveTips will not be liable if your device gets damaged or bricked during the process.


  • Unlocked bootloader and a custom recovery installed. If you do not already have this, or are unsure about how to achieve this, this ROM is not meant for you.
  • Running stock .55 ICS ROM or one based on that firmware.
  • Leaked Jelly Bean ROM for Xperia S (Download it from the XDA link at the end)


  1. Begin by downloading the ROM and copying it to your phone’s SD card.
  2. Now reboot the device into recovery by powering it device off and then turning it back on while hitting the ‘Volume Down’ key a couple of times as the device boots up.
  3. To be on the safe side, make a backup from recovery.
  4. Navigate to ‘mounts and storage’ and make sure that /system partition isn’t mounted. If it is mounted, make sure to unmount it.
  5. Go back and perform a full wipe data/factory reset, followed by wiping cache, and then wiping dalvik cache from the advanced menu.
  6. Next, select to install zip from sdcard,  then choose zip from sdcard by selecting the ROM’s zip file you copied to the phone earlier.
  7. Once the ROM is flashed, simply reboot the device.

The first reboot may take quite some time, but that’s nothing to worry about. For updates and queries related to this Jelly Bean leak, head over to the XDA forum thread at the link provided below.
