Install Android 4.4.4 KitKat On Sony Xperia T With Carbon ROM

Sony stopped Xperia T’s Android updates on Android 4.3 Jelly Bean and since then there hasn’t been any official word by Sony whether it will update it’s device to any further version of Android or not. Google is all set to launch Android L and since most of the high end devices are running on Android 4.4.4 KitKat, this definitely leaves the Xperia T owners in a little bit of disappointment for not having the latest Android version running on their device.

In this case, the only solution is to get a great custom ROM and give your device a new life. This job for Xperia T has been done by XDA senior member Alx31TLse who brought us up Android 4.4.4 KitKat based on Carbon ROM, a very popular and one of the most widely used Android custom ROM by Team Carbon. This ROM is available for many Android devices. In the succeeding post we are going to install this Android 4.4.4 KitKat with Carbon ROM on our beloved Sony Xperia T. In case you’ve been looking to update your device, you may have spotted the right place. Let’s go through the early preparations and then flash this ROM.

Early Preparations:

1. This is only for Sony Xperia T!

This custom ROM is only for the device mentioned above. Make sure that your model number matches the one listed above. To do so, go to Settings > About Device on your device and see your model number. Flashing this ROM on any other device will result in bricking it so make sure that you meet this requirement first of all.

2. Battery should be charged at least over 60%.

Make sure that your battery is charged enough to complete the flashing process. In case your battery is low and your device goes dead during the flashing process, you may end up soft bricking your device as it won’t complete the flashing process.

3. Unlock Bootloader.

Your device’s bootloader must be unlocked in order to flash this custom ROM. You can unlock it by using our Sony bootloader unlock  guide.

4. Backup everything!

Just to be on the safe side, you may consider backing up each and everything from your Android device. This is highly recommended so that in case anything goes wrong, you still have the access to all of your data and you can restore it immediately. You may backup everything as listed below.

• Backup SMS Messages
• Backup Call Logs
• Backup Contacts
• Backup Media – Copy your files manually to your PC or Laptop.
• Titanium Backup – If already rooted, use Titanium Backup to backup all of your apps, system data and other important content.
• Backup Nandroid – If CWM  or TWRP installed previously, otherwise skip this step and perform this at the end of flashing.

5. Disclaimer

The methods involved in flashing custom recoveries, roms and rooting your phone are highly custom and may result in bricking your device, and has nothing to do with Google or the device manufacturer that is Sony in our case. Also rooting your device will void its warranty and you will be no longer eligible for any kind of free device services by the manufacturers/warranty providers. In case of any mishap we may not be held responsible. Follow these instructions to the letter to avoid any mishap or bricking. Make sure that whatever you do, you are doing it at your own responsibility.
