It has been just a few hours since we posted the leaked screenshots of Jelly Bean on Sony Xperia P and DooMLord on XDA forums has leaked the firmware 6.2.A.0.399. The firmware is not the one you might get when the OTA update is rolled out for your devices but this one is the firmware that is meant for developer devices, something similar that we saw for the leaked JB for Xperia S. This is the firmware that Sony used for testing on the developer phones and hence may not be functional.
While this leaked firmware gives you the most of the OTA update you might receive, there are chances that Sony might add or remove features to this leaked firmware. As of now, the following does not work on this leaked firmware:
- kernel provided here DOES NOT HAVE WORKING RECOVERY
- baseband is NOT recognized
The ROM is already rooted and has busybox installed.
- unlocked bootloader
- previously on stock ICS ROM or roms based on that
- supplied ROM & kernel
- any existing kernel with recovery
Steps to Flash Leaked Jelly Bean Firmware on Sony Xperia P
- Download the ROM zip file (563 MB) and Kernel zip file.
- Place the ROM zip file in your device’s SD card.
- Boot your phone into CWM and make sure /system is not mounted.
- Go to “Install zip from SD card”>”Choose zip from SD card” and select the ROM zip file.
- Flash the zip file. It will take long time to flash because the zip file is heavy.
- Turn off the device and boot it into fastboot mode while connecting it to the PC.
- Extract the contents of the kernel zip file to get kernel.elf and place it in the folder that contains ADB files.
- Open Command Prompt in the same folder and run the command:
fastboot flash boot kernel.elf
- Reboot the device using the command:
- Your device will now be running the leaked Jelly Bean firmware.
