1) If I wish to later do warranty repair and I currently have a locked boot-loader is backing up the TA going to give me a 1:1 undetectable root and later unroot if I choose. (i mean all my gracenote, bravia, and other DRM's be returnable to stock condition)? (if so which method is the BEST.. ? seen a couple now)
2) My stock firmware doesn't seem to be on the FTF list is this possible I have a : c6906 C6906 14.3.A.0.757 Generic CA R10 ??? This one is on the list I don't think so ? Perhaps I am reading the string from the wrong spot.. ! In which case anyone know what to do to make a backup ?
3)Everyone hates this question but I have to ask does anyone here know of a way to unlock a locked bootloader :YES flagged device; I feel like a dink asking but after sifting through hundreds of posts there seems to be contradiction as in some people eventually figure it out and/or have unlocked z1's which I have read elsewhere that every single z1 comes from factory with bootloader locked yes?
Answer one of these questions for me make my day and you will have my many thanks to come
