Cgeist, Mar 14, 2019 : Hi everyone I got my T-Mobile OnePlus 6T about 3 weeks ago and I'm sorry if this has been asked before I didn't see it on here. I am an avid Android fan and love testing new releases of software and apps. I tried downloading the open beta for the 6T and I can't figure out how to flash it what am I doing wrong? Is my phone locked to receiving updates from T-Mobile? or can I update and just not doing something right? thanks in advance for any help!
