I learned since that if the update from auto-update is done, 4.3's bootloader is no longer available and it can no longer be restored to 4.1.2.
I am learning terms and procedures to the best of my novice abilities, but I am still confused on how and IF I can keep my 'download-in-progess' GNII that is still 4.1.2 at 4.1.2.
Verizon and Samsung say absolutely not as you probably know and that it would be a forced installation and factory reset now or afterwards = 4.3.
SO , my question is:
is there a master link for this procedure (and a best ROM?!)
Also do all procedures to accomplish my goal of not updating to 4.3 involve rooting that would void the warranty as FAQ#19 states (? Or is there a non-rooting method?
