You just can try new mbn.So I did everything without you. I had to download efs again. then it was no problem. but unfortunately even that mbn from nokie 8 doesn't work.
I figured out how to enable volte on tmobile pretty easily if you still have the phone to try it out on! My guide on how to do it is posted in this thread.My wife is far too busy and has no time for my nerdy ways! Even though she is gonna miss it (shoot I am too) she is gonna return the phone. She gets way too many business calls and it keeps dropping service sporadically due to being on T-Mobile. Thank you and I hope your tutorial is helpful to others!
For some U.S. carriers may it work so. I have read in ROG 2 or 3 forum about it. Maybe because Asus has build in these carriers but not activated. For other you need whole procedure....
Tip: you can check your setptop status with getprop e.g. getprop persist.vendor.dbg.ims.volte If you get a "1" back it's activatetd.
That's strange. What happens in the "normal" diag mode: setprop sys.usb.config rndis,diag,adb ?Trying this but I can never get my wife's phone to show up in QPST and notice connecting her phone vs my G8 behaves differently in Device Manager. My G8 I'm able to see my Com Port number via Device Manager. The Zenfore only shows up as ASUS Android Composite ADB Interface and under Portable Devices. Weird.
