I own Nexus 6P, and am having nothing but problems with it. Definitely, the worse device I ever owned. It was rebooting daily (note past sense as this is not my main problem) often multiple times for no reason but the main issue is that it ended up in an infinite reboot loop.
Here is the description of problem: 2 days ago, phone suddenly rebooted but this time, "Google" text would show up, then black screen, and this would repeat endlessly, phone would never reboot and ends in bootloop.
What I tried to fix this?
Press Power button and Volume Down and hold until menu shows allowing you to do following and description what happens:
restarts phone but ends in infinite boot loop again
Reboot bootloader, - no changes
Recovery mode, - no changes but see 2 below
Barcodes, - shows barcodes
Power Off. - turns off the phone
I tried all of these without success - phone is still in endless boot loop showing "Google" text on black background
Press Power button and Volume Down and hold until menu shows, then select Recovery mode. Soon after, "No command" shows on screen with little green android icon with red triangle. Next, press Power button and Volume Up and release. This bings Android Recovery screen with yellow text at the top showing google/angler/angler, 8.1.0, etc etc and blue menu at the bottom with options to:
Reboot system now - tried it, nothing changes
Reboot to bootloader - tried it, nothing changes
Apply update from ADB - havent tried it, dont know what to do with it
Apply update from SD card - tried it, get "cannot mount /sdcard" Installation aborted
Wipe data/factory reset - formats /data and /cache but nothing is fixed, still infinite reboot loop
Wipe cache partition - same as above, just formats /cache
Mount /system - nothing changes
View recovery logs - shows number of logs
Run graphics test - shows "Installing system updates" and then shows "Error". No changes
Power off - turns off the phone
I also tried every single of these options as described above but nothing will boot the phone. It always ends up in infinite boot loop with "google" text on black background showing and disappearing forever.
I have found that phone rebooting and above described infinite boot loop are so common that there are many complaints and even a law class suit going on against google and Huweii as per link Google and Huawei Will Face Class Action Over Nexus 6P Bootloop Issues
I have tried many suggestions, Google one's are useless as they all assume phone actually boots up, so ridiculous, and have no resolution.
How to fix this issue? How to install manually Android OS on my phone if I cannot do anything else to resolve this?
You can fix this issue according to Google only if you can somehow enable EOM but to do that you need to boot your phone. Some suggested to put phone into fridge or heat it up with hair dryer or heat gun. If you are lucky with this, you may get change to boot it up briefly and go to setting to enable OEM, then you can attempt to fix using fastboot but even this is not working all the time and will significantly downgrade performance of your phone
I tried both without success, heated it up for 1 hour, it was scorching hot but it would not boot up. PUt it in fridge and freezer overnight, still no way to boot it.
