Hello all hope somebody will give me proper guidance and links of threads.
Just got my Xperia ultra today it is United Kingdom (GB) model number C6833 with Build number 14.2.A.0.290
I am very new to Sony Xperia phones, have bit experience in rooting HTC, Archos, Samsung but Xperia is new to me.
I did some research and found it is only possible to root 290 firmware with Unlocked bootloader. Here is the problem start I don't want to loose my DRM keys by unlocking bootloader, wanted to have backup of TA partition before I unlock my bootloader if I needed in case. I can't backup without Root so I am stuck and confused what to do? Is it possible to downgrade to other firmware to root my Xperia ultra then I can backup my DRM keys. Also found some posts by users saying if you downgrade from 290 you loose IMEI so is there any solution?
your help and guidance will be highly appreciated.
