Easily Backup the TA Partition on Your Sony Xperia Device

Some time ago, we talked about the importance of backing up the TA partition on Sony Xperia devices. Doing so on Sony Xperia devices saves your DRM keys. Why is this important? These keys are required in order to use a few proprietary software bits such as Bravia Engine in the Gallery app and OTA updates.

As we learned before, however, once you unlock your bootloader for the first time, these DRM keys are irreparably lost unless you previously created a backup. Luckily, there are great tutorials that teach you how to backup your TA partition, given that you do this before the initial bootloader unlock.

Now, thanks to XDA Forum Member DevShaft, there is a streamlined Windows batch file that does it for you. All you have to do is download the latest version, connect the device with ADB enabled, run the batch file, and choose from the menu options.

Obviously, this is of no use if you’ve already unlocked your bootloader without a backup and you have already lost your DRM keys. However, if you’re thinking of unlocking your bootloader for the first time, head over to the original thread to backup your TA partition easily. A list of known and assumed supported devices can be found below.
