Technically, you didn't have to be rooted to get a leaked update. A full, signed update of 5.7.893 was around that could be flashed in stock recovery. That's what I used. So, the root voids warranty argument doesn't NECESSARILY ring true here. Nonetheless, most of us that applied the leaked update, most likely rooted, as well, yes. But that's only an assumption.
Well thanks for throwing some gray into the mix!
Regardless, rooted or not, "you" took something on our phone that was unofficial, and there were a LOT of warnings floating around about potentially getting off the upgrade path. By returning it to Verizon and acting like there's something wrong, knowing full well what you did, it's deceptive, and we do not encourage that here.
This needs to be the end of the discussion as this can quickly derail into an ethical debate, and that's not what this thread is about.
I'm just curious what 5.9.901 improves upon, hopefully more than just adding some apps!
