This happened today:
- I was using my Nexus 5X when it suddenly started rebooting.
- It got stuck in a bootloop. It would never boot past the Google logo and I couldn't turn it off.
- I was able to enter fastboot mode and even recovery mode from there.
- I wiped the phone from recovery mode which didn't help.
- I left the phone lying with the fastboot menu open because I thought maybe it is overheated and will cool down (it was slightly warm).
- When I returned, the phone was off. I started it and this time it went past the Google logo up to the Android logo (with the animation). However, after displaying "Android" it would just power off.
- I tried to boot it a few times but it would never go past the Android logo. Eventually the bootloop started happening again.
- I am now back to step 2 except I can't enter recovery mode any more. If I choose recovery mode from the fastboot menu, I never see the lying Android figure with the exclamation mark.
I found many tutorials about fixing bootloops on the Nexus but they all seem to require an unlocked bootloader.
The bootloader on the device is locked. I can see the device in
fastboot devices but I can't unlock it.
Any idea how to repair this? Can I somehow flash a factory image onto the device even though OEM unlock is disabled? There is no data on the device that would need to be preserved. I'm ideally looking for a Linux-based solution.
