On Sony Xperia android devices, the partition that contains the DRM Keys, IMEI, Baseband and few other essentials of the Sony android devices is called TA. This partition is usually lost when you unlock your Sony android device's bootloader -I guess you know the risk already.

Loosing the TA partition means your Sony android device may never have network again -this is why it it is essential that you backup the TA partition before you unlock the bootloader of your Sony android device.

Here, I will walk you through the step by step guide on how to backup TA partition of Sony Xperia devices using TA Backup/Restore Tool.


1. Download TA Backup/Restore Tool from here.
NOTE: this tool requires that your Sony Xperia be rooted. See DooM's Lord Tutorial for Rooting Xperia Devices here.

2. Extract the ZIP file to a folder on your PC.

3. Navigate to the folder where you have extracted the TA Backup Tool.
 NOTE: at this point, make sure no other program is using ADB.
