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!!!
Type *#837837# into your phone dialer and report back your OS build and PRD.
I am so sorry for the delay, im at work and got really busy.
I entered that number and it comes back with this error msg:
connection problem or invalid mmi code
oops, I typed it in wrong.
PRD 63116-036

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

Even if the AT&T model?
Yep.
