Sony had released new Jelly Bean OTA updates for several Xperia devices, like Xperia E Dual and Xperia ZL and we have showed you how to manually apply the firmwares on the mentioned handsets. Well, now we will be checking on how to manually update another Sony branded smartphone, the Xperia P model number LT22i – therefore by using the next guidelines you will be able to learn how to install the official Jelly Bean 4.1.2 6.2.A.1.100 OS on your device. Stick to the lines from below as the guide is complex and risky, so you shouldn’t mess things up.

The 6.2.A.1.100 software is the latest Android 4.1.2 Jelly Bean OS released by Sony for your Xperia P therefore if you want to improve the Android experience that runs on your handsets and if you want to customize and optimize the performances of your phone, then don’t hesitate and complete this step by step guide.

This tutorial will be more than useful for those who haven’t received the OTA JB 4.1.2 6.2.A.1.100 by now, or for those who owns a rooted Xperia P (in that case the official update will not be OTA received). It’s also important to know that this operation is official, so by completing the same the warranty of your handset will not get voided. Since you are flashing the stock Android OS, if your Xperia P is rooted or installed with a custom ROM, now you will be able to restore the lost warranty, revoke the root access and re-flash the default Jelly Bean firmware.

The 6.2.A.1.100 software is stable and comes without bugs and things that aren’t working properly. Also, according to those who have applied the Jelly Bean 4.1.2 firmware, the OS is smoothly running on the Sony Xperia P, not to mention that the battery life has been improved, which is an extremely important aspect to consider when dealing with OTA updates.

Since this is the manual flashing method, for being able to complete the same you will have to: ensure that you can access a computer or notebook where you will have to download and install some tools; so as you can already tell, your phone and its USB cable will also be required. Then as usual, when dealing with manual installation procedures, you need to: uninstall the antivirus, Firewall and any other security protection that is installed on both computer and handset; charge the battery of your device, or at least ensure that there is more than 60% power left; check the USB debugging option from path: “Settings -> Applications -> Development -> USB debugging”.

Another thing to perform before starting the flashing procedure is a backup. In rare cases the data which is being saved on the internal storage memory of your device might get wiped out. Well, even though that can happen only on limited cases, you should still download, install and use backup and restore apps for saving your personal info, accounts and data.

The Jelly Bean 4.1.2 6.2.A.1.100 OS has been official launched by Sony for the Xperia P model number LT22i, which means that you shouldn’t apply this tutorial on a similar or different device. The next lines are being compatible only with the mentioned smartphone – flashing the ROM by using the next steps on a different handset will probable brick your Android powered device.
