My son's stock 2012 Nexus 7 running Android 5.0.2 is stuck in a boot loop (swirling dots) - it never progresses past this point. I can boot into (stock) recovery and wipe the cache, but this doesn't help. I also tried connecting it to a PC and repeating the process, but had no luck with that either. Lastly, I tried accessing it via ADB while stuck in the boot loop. ADB reports the device ID followed by "unauthorized". I'm not sure if I never used ADB from my machine on this tablet or not, but I'm thinking that the "unauthorized" may be resulting from it possibly not having progressed far enough into the boot process to know that my machine is authorized.
The only other thing I can think of doing short of a factory reset is booting into safe mode, but I don't think that's even possible without getting Android to boot first. Is it possible? If so, how?
Am I stuck doing a factory reset as the next step, and if that fails, flashing the factory image, or are there other non-destructive steps I can take?
