You've given me even more homework, but I greatly appreciate the response
I currently have a stock (unlocked/unrooted) Tab Z and if I understood the 4.4.4 posts I've read, the best method to keep root(towelroot for 4.4.2+older) and files is install via OTA which requires an unlocked bootloader, which requires a code from Sony so.... a brief summary of steps to keep my unit as 'open/versatile' as possible here would be....
1:Get code from Sony
3:Install Flashtool and root via towelroot (the order here is not important?)
4:Back up files
5:Install 4.4.4 via OTA
And then I'm left to be able to move back and/or install older firmware?
If this is a PITA to answer, I understand - appreciate any help
Before unlocking bootloader BE SURE TO BACK UP YOUR TA PARTITION OR YOU WILL LOOSE DRM LICENCE KEYS FOREVER !!!
Google "Sony DRM TA backup" to find more information.
