"Subsystem Crashed: Modem" AT&T G965U Read Codes via Server

[aamonga]

Hey guys, I'm trying to unlock my Galaxy S9+ using Read Codes via Server on the Z3X but it keeps getting stuck on "SS RDX" and says "Subsystem Crashed: Modem!" below it.

I have no tested yet. I´m in process of doing it.
**Do it at your own risk if you want**
You should flash Combination File modem (only modem), then read codes and save them, flash stock firmware, then input codes.

This should work for Bit 3.

I already tested this process in a Bit 3 G965U. Here´s the log:
