Please help. My 950Xl is stuck .29 build. It's duel sim unlocked, i have it on at&t. I tried restoring to the earliest build of 12-12-15 and it still loads with .29. I tried all the insider previews, then opting out of insider. I must have factroy rest this 3-4 times in the last 2 weeks, trying everything. Anyone know what I can do?
