I've been asking myself that same question all along.@onlycash I have constructed a small/random theory with no real basis. Could your problems be related to OOS 11? It sounds as dumb to me as it probably does to you, but I'm getting a nagging sensation that folks with success on your model aren't running the new update.
Just a weird hunch with no proper research, but I find it weird that you have these "unique" problems so I'm just spitting random junk at this point.
The big problem is they pushed 11 out and made it impossible to NOT install it, even if you had chosen 'do not auto update' in developer options. I didn't get my bootloader unlock token till after that point.
I'm not sure if I can go back to 10 and if so how. Also even if I did how would I root after it pushes 11 on me?
As you can see I have more questions than answers.
PS: I would be perfectly happy to have a rooted 10 or 11 and never update again. I only use these phones on WIFI in my living room and I don't care about updates in general.
