Hi All,
Really hoping someone can suggest a possible solution for this one, only had the phone a few months!
So, Chinese released M9. Unlocked. Stock recovery, not rooted. Gapps installled.
Everything perfect, then today I got the 5.1 update.
Seemed like a slightly iffy install process...looked a little like it failed a couple of times and tried again.
Finally finished, the phone shows the white screen with the one logo, takes a while, opens on the desktop and turns off, back to the white screen with the logo.
I have been able to boot into safe mode, which is stable
I have been able to get to download mode and bootloader. Neither of these offer a cache wipe or a factory reset.
I have not been able to get into recovery mode, it shows a phone with a red triangle and an exclamation point.
So for my (largely uneducated) part I have two theories for the cause:
1) Gapps is somehow proving a problem, either faulting the install or causing a fatal error on startup
2) Since the update was notified and downloaded while on a VPN via Hong Kong, I wonder if I accidentally ended up with the HK version in which case I suspect there may be hardware differences (at least the radio). This seems unlikely, I would hope there were enough checks in place to prevent this happening.
No solid idea where to go from here. I have not yet tried ADB access, but even if I can connect, what will I do? Flash a new ROM? I'd rather not. And surely I'd need to root in order to do that....
At a loss, any potential solutions welcomed whole heartedly!
Thanks...
