Since the recent forced update to oero I was currently on 7.1.2 with root and twrp recovery after the forced update I lost root and twrp recovery I was wondering if I can regain root without a computer since I don't have access to one right now since my PC is down if there is a way of doing it would be great thanks!
Yes, with a rooted phone and an OTG cable. Rooted phones can run ADB and fastboot from terminal emulator. I did it myself multiple times on multiple devices.
