Update Xperia T to Android 4.3.1 with AOKP Custom ROM Firmware
Are you tired of the same Android OS that is running on your Sony Xperia T and you won’t say no if a new update will be released? Or maybe you want to test the latest Android 4.3 firmware on your own Xperia T but since there is no OTA available for your handset, you don’t know which custom ROM to use? Well, in order to help you out, during the present step by step guide, I will show you how to easily update your Sony Xperia T to Android 4.3.1 Jelly Bean software, all by installing the new version of AOKP custom ROM on your phone.
Actually we will be flashing the nightly build of AOKP on your Xperia T, the ROM being officially released for several Android devices, the Xperia T being among supported handsets. The best is that the latest version of AOKP firmware is coming with the latest Android software, Jelly Bean 4.3.1. As you can already tell, after completing this tutorial, you phone will be running on a custom variant of the mentioned OS. So, you will be getting custom looks, custom UI, custom features and custom settings, as after all we are talking about a custom ROM and not about an official Android update.
Therefore, AOKP has nothing to do with Sony or with Google. The ROM is developed by third party devs and brings with extra features and apps that cannot be found on the stock version of Android 4.3. That’s why this is an unofficial operation. Applying AOKP firmware on your Xperia T will be risky, though nothing bad will happen if you use the guidelines from below. Else, you can damage your phone’s system while trying to update to JB 4.3.1 or worst you can even end up in bricking your Sony Xperia T.
Anyway, since we are talking about “worst scenario” you should know that the warranty of your handset will get void as soon as you will start this update procedure. Well, actually at this point the warranty should be lost because for being able to update your Xperia T to Android 4.3.1 with AOKP custom ROM, root access must be gained. Root is also unofficial and refers to the following: when gaining root access you remove the factory and default restrictions from your phone so that you can access the internal system from the same; this is when the warranty gets void; anyhow, do root as AOKP must access some internal files and programs and also the ROM will add new custom programs the mentioned access being granted only via root.
So, try not to mess things up as the warranty can’t be claimed. Don’t panic though because afterwards you can choose to restore your phone’s warranty. For doing that you will have to revoke root access or reset flash counter – just downgrade the Xperia T to stock Android OS, or update with an official release of Jelly Bean firmware.
Up next, make sure that before starting the steps from below you install a custom recovery image on your handset. It’s important to replace the stock recovery with a custom one because a custom ROM can be flashed only in this condition. If possible use CWM or TWRP recovery – CWM recovery can be downloaded and installed via Google Play. Also, first root your Xperia T because the custom recovery image can be applied only on rooted Android based devices.
The last thing to do before heading to the proper tutorial is a backup operation. Unfortunately a wipe will be required, or else the Android 4.3.1 AOKP firmware will not run on your Sony Xperia T. So, if you have something important stored on your smartphone, take your time and backup the same. Also, it should be a good idea to save the contacts list, test messages, personal data, accounts and info on your way.
On the other hand, a computer, your smartphone and its USB cable will be required. You will have to connect your device with the computer, so on your phone USB debugging option must be enabled: go to “settings -> menu -> developer options”. This is a manual update operation and in rare cases the antivirus programs are interfering with the same; so as a recommendation, deactivate the security protection that is running on your computer before going any further. Due to same considerations, consider in charging your Xperia T as you don’t want to brick your phone – that will happen if during update operation your handset will get turned off by itself (it is indicated to charge the battery if the power is lower than 50%).
It’s important to apply this guide only for the Sony Xperia T; the Android 4.3.1 AOKP firmware used below has been designed to run only on the mentioned handset, so don’t install it on a different or similar Android based smartphone or tablet.
