Hi, thank you for your reply.
I just looked up what exactly the "TA-Partition" is and i guess the only thing that was worrying me (loosing Bravia) is not up-to-date anymore
So lets get started, i looked up what i need to backup the "TA-Partition" and if i understood everything its basically having a rooted Xperia-Z and a double-click on a .bat-file?
So i guess the best would to not upgrade any of the shown OTA-Updates by Sony, and root the 4.2.2-Stock ROM that is on the device right now?
As far as i know rooting 4.2.2 isn't really a problem right now, agreed?
So after sucessfully rooting the Sony Xperia-Z its just backing up the "TA-Par tition" with "TA-Backup"-Script?
After that, its unlocking the Boot-loader over the Sony-Website (IMEI, Name, Email....) so that they send you the Unlock-Code, after that you'll have to use fastboot to finally unlock it?
(If i check the Service Menu "Rooting Status": there is nothing behind it, but the bootloader-unlock allowed: says yes, so no problem right?)
After that you most likely are done for the moment, until you decide if it should be CM10.1Stable or CM11Nightly, rig
How's the status of CM11 right now, any known major bugs?
Thank you already for your help
