I'm at a loss here, i have nougat on my mate mate 8 but i completely forgot that you had to root nougat in a particular way. Anyway, i don't have access to erecovery, power+volUPvolDown doesn't work and i can't get access to fastboot. The only thing i do get is power to the screen and my 'your phone is unlocked and can't be trusted blah blah' message.
I need to flash a recovery.img, system.img and any other relevant img. How can i do this with the phone in this state?
