It's locked? I have installed this many times on my TMo S8+ and never had this happen. Even when I had temporary unlocks, it would remain unlocked until the unlock expired. If you want the device unlock app to work again you'll need to go back to official TMo firmware.

Just by installing the unlocked software does not unlock the phone. was your phone unlocked previously and then you switched to U1 software? I am pretty sure you can request an unlock from the tmobile site. have you tried that? other than that y not just flash back to oreo and unlock from the stock tmobile rom. DRL7 is a terrible build anyway compared to whats out there and t-mobile is in the testing phase so official pie will be out soon. just a few ideas.

my phone is fully paid and it was unlocked before. I installed android pie and get locked again. I cleared a last bill and I had back and forth with theme for 2 months. many calls. they phone is not on their whitelist anymore so should work but there is not no way I can make the device unlock app work. I tried with tmobile sim, another sim and wifi nothing the device unlock apps opens and closes with no connection to their servesrs. Tmobile at the end says they cannot do anything since I am using a version not supported. anything you can think of?

can I go back to the last officie Tmobile build based on android 8 with odin or I will brick my phone? in any case to put the official ui 9 build from tmobile when it comes out I most likely need to do it with odin or sideload correct?

You can revert to the official T-MOBILE build. If you're on the official build then you should get the OTA for pie when it's out.

Thanks so I just use odin to put back android 8 with the official android 8 t-mobile build? at least I can get their support. no issues in reverting firmware back from android 9 to android 8?

Perhaps q&a and not general discussions

Yes you can just go ahead and downgrade. I do it all the time and haven't run into any issues. I also have a T-Mobile S8+.

Thanks I will try and let you know

tried odin on macos via java. downloaded tmobile official build. phone in download mode success. asking for PIT file. I extraced it from the CSC file and now it says the odin file corrupted. Suggestions? I tried a differente cable. I will now try to install via odin on pc and maybe downlod the build again. any other suggestion? I am worried the phone cannot write on the phone flash memory whihc might be the same issue why the tmobile unlock app does not work. yet the phone works perfectly for any other app and oS

I've never gotten Odin to work properly on my Mac. However, you can use VirtualBox and run Windows in there. That's how I use Odin. I'd download the build again and see if that fixes anything. Please try on a Windows machine (VM or PC).

Will do that then and let everyone know
