Did you try to flash T-Mobile phone with At&t firmware ? At&t firmware will ask to put network unlock pin and AT&T are SM-G955u also.

6. Plug your phone into your computer (NEEDS TO BE WINDOWS) with Odin open
7. Make sure your device is connected and recognized by Odin.
8. Click start.
9. One the phone reboots run the ADB command, adb reboot bootloader
10. Open modded Odin and flash the EngBoot
11. Click start
12. Once the phone reboots type the command adb reboot bootloader
13. Put the HOME_CSC of the G950W firmware into the CSC part of Odin (unmodded)
14. Click start
15. Open IME setting on Factory Binary
16. Type in *#243203855#
17. Select XAC
18. Click install
19. Wait for phone to reboot
20. Once it does open terminal and type in adb shell

Even if you flash G955USQU1AQD9_G955UOYN1AQD9_USC the CSC is still TMB. You probably need to try after changing the CSC to ATT and then try to unlock.

TMB T-Mobile
XAA Unlocked US
SPR Sprint
CCT Xfinity Mobile

Don't entirely know which ones these are:
GCF World Wide
ACG Some Mid West Carriers
LRA A bunch, cant figure it out


ACG is C-Spire a Sprint type service
LRA is LTE in Rural America a Verizon type service
GCF is some unknown roaming service


I think it would be better to do the carrier change first, and only then read the unlock code. Because if you read the code first on the original carrier, then the code may not work properly on the changed carrier.
So try to change to ATT carrier first, read the code, and enter code.
Report back please.
