Sony Xperia P Official Android 4.0.4 ICS

This guide is intended only for Sony Xperia P having model number LT22i . Don’t try to implement it on Xperia U / Xperia Sola or on any other device else it can damage your device in anyway.

Pre-requisites:

• Charge your phone at least up to 70% so that flashing process won’t get interrupted.

• It is highly recommended to backup all your data from internal memory (includes contacts, messages (SMS/MMS), call logs, Internet APNs etc.). Your phone data will get lost after installation of this firmware (excluding External storage).

• Download Xperia Flashtool from here. We’ll be using it for flashing the firmware.

• Download Xperia P LT22i Official Android 4.0.4 ICS Firmware package (6.1.1.B.1.75) from here.

• Install Flashtool that you’ve just downloaded in your computer. For the sake of convenience, install it in root directory of C: drive.

• Navigate to ‘C: –> Flashtool –> Firmwares’ and delete all the data over there if anything is present.

• Now move ‘Sony Xperia P_6.1.1.b.1.75_Generic World.ftf’ file in the above mentioned directory.

• Open Xperia Flashtool. Select Flash option (Black Bolt icon) from the top left corner of the tool (Refer to image given below).

• It will ask you to select either Flashmode or Fastboot mode. Select Flashmode & proceed further by hitting OK button.

• On next screen, Firmware selection window will appear. On left side, select ‘LT22i (version 6.1.1.B.1.75)’.

• In right side of the tool, tick following 4 options (Caution! Don’t tick any other option than 4 mentioned below).

1. Wipe data.
2. Wipe cache.
3. Wipe apps log.
4. No final verification.

• Press OK. Wait for Flashtool to prepare firmware installation.

• Now, it will ask you to connect your phone. Before you connect your phone to computer, enter into Flashmode on it. To do so, switch off the phone completely. By holding Volume down key, connect it to PC. If done correctly, you should see a ‘green light’ on the power.

• After establishing proper connection with the computer, flashing process will start. Firmware installation process may get stuck around 93%, which is normal. It stays there for 20-30 seconds and not more than that.

• Once you get “Flashing finished” message in Flashtool, remove your phone from PC & wait for it to reboot (It may take more time than usual for booting the device, which is normal. So don’t get panic & be patient).

Congratulations! You have successfully updated your Xperia P LT22i to Android 4.0.4 ICS 6.1.1.B.1.75 firmware. If you need any help, we’re always there for you. Just comment it below & we’ll reply as quick as possible. Enjoy..
