While the update went live just now, folks on XDA have created an ftf file for the 6.2.A.0.400 Android 4.1 Jelly Bean firmware for the Xperia P. With this tutorial, you will be able to udpate your Xperia P to Jelly Bean using FlashTool. Why should you use FlashTool to update? You probably unlocked the bootloader of your Xperia P or your region hasn’t received the update Over The Air (OTA) yet. In both cases, you can go ahead and use the FlashTool to flash the firmware. I personally recommend this method because you can flash it whenever you want, the ftf file rests in your hard disk and you don’t need to use Sony Update Service (SEUS) every time you wish to flash the stock ROM.
Please note that this is an official firmware so a rooted device will lose root access after this update. Never mind, you can root it again. Also, this update does not affect the state of your bootloader. If you had an unlocked bootloader, it remains unlocked.[box type=”shadow” ]Since this update will wipe all data on your device, we recommend you backup data using our backup guide and have the latest drivers installed on your PC.[/box]
Please note that the firmware you flash with this tutorial is only for unbranded phones. Your device should not be locked to any network.
Steps to Update Sony Xperia P to Jelly Bean Firmware
- I assume you have downloaded FlashTool from our device drivers page. Open the FlashTool folder (it might be in C:FlashTool) and find the drivers folder. Right click on it and select “Run as administrator” and install the drivers for your phone. Make sure you check the flashmode and fastboot drivers at the end of the list.
- Download Xperia P LT22_6.2.A.0.400_World Generic.ftf and place it in the firmwares folder found inside the FlashTool folder.
- Run FlashTool.exe file. FlashTool opens and it must say “Device disconnected” at the end.
- Turn off your phone and boot it into flash mode. To do this, press and hold the volume down button and inset the USB cable that is already connected to the PC running FlashTool. You must see a green LED light up on your phone.
- FlashTool now says “Device connected in Flashmode”.
- Click on the thunder icon at the top left in FlashTool, select Flash mode and then select the ftf file you placed in firmwares folder.
- Click on OK button and the ftf file will be flashed to your phone.
- Once the process is finished, FlashTool says “Finished!” at the end.
- Disconnect your device from PC and reboot it.
