[Nexus 6 Q&A, Help & Troubleshooting] behr00z:
Nexus 6 stuck in fastboot

Hey there.

weird story happened to me. I've never been into rooting, custom ROMs n stuffs for my Nexus6 phone. last night I saw a 'Not Responding' error for Messages app and I restarted the phone. that was the last time I saw my android home screen :rolleyes:, it rebooted into fastboot mode and I had no idea what it was about.

anyway I started to dig around to find a workaround to fix it, first thing I tried was Factory Images for Nexus Devices on Google developer webpage.

Well, errors appeared.

1 -

~ fastboot oem unlock
...
(bootloader) Check 'Allow OEM Unlock' in Developer Options.
FAILED (remote failure)
finished. total time: 0.002s

but I have not access to Developer Options to check Allow OEM Unlock,

2 - My Fastboot Flash Mode (Secure) says 'Device is Locked' at first but when I hit the power button it changes to UNLOCKED. and also my baseband changes to empty when I hit the power button.

I continued the steps described on that page, and they didn't work. these errors appeared:

the whole output for flash-all.sh ( I'm on mac )

I tried a lot of ROMs there, even tried to unzip the package and flash each one separately but I always get these errors:

(bootloader) Failed to flash partition
FAILED (remote failure)

I then fired up a windows XP virtual machine I had and installed Nexus Root Toolkit v.2.1.0 and played there. nothing happened.

it can only flash the twrp recovery and run it, but nothing works there. even I tried to push a SuperSU file to it and install it. errors on mountings appeared.

beside that I really don't understand why the hell this happened, I have no idea what should I do now. Any kind of helps is appreciated
