    Hi all,
    Just bought unlocked Att branded Keyone 100-1 that I'm using on TMobile.
    It's stuck on 7.1 and I've tried inserting an ATT Sim card but didn't work, said it was current with no upgrades available.
    How can I upgrade to Oreo?
    I'm not real tech smart, just enough to get me in trouble. Please help??
    Thank you very kindly!!!

    Download and install the Mobile Upgrade Tool on your PC, put your device in fastboot, plug it in, and run the tool.
