Hello Devs

I want to roll back from Android Nougat to Marshmallow by installing TWRP.... I have my bootloader unlocked on my Nexus 6P but since I have the error of Download Mode DISABLED in fast boot mode Im unable to flash the firmware through ADB.

Kindly help.:crying:

If you have an unlocked bootloader and can boot into it, does it not recognize your phone or simply not allow you to run commands? My download mode reads as DISABLED in my bootloader and I can run fastboot commands. I think you're a little confused on terminology, too. You'd sideload software via ADB with TWRP or for an OTA, your stock recovery. You'd fastboot flash partitions via the bootloader.

I can boot into fast boot mode by hardware button combo pressed but its not recognising any fast boot or ADB commands when I connect it on my laptop

When connected by USB and in your bootloader, run 'fastboot devices' and if it doesn't show your serial # then it isn't recognizing your phone, likely a driver issue.

Do not try to do that. We have a lot of bricked devices (Including Mine) after we tried rolling back to Marshmallow. Just a warning. If you still want to take a risk, go ahead by all means.
