LG V35 Thinq (AT&T LM-V350AWM) Unable to Unlock


Greetings. I'm pretty sure I am stuck without a solution, but figured it couldn't hurt to ask if anyone knew of a one.

I had to switch firmwares on this phone to the Korean version for FRP Bypass. However, there are no KDZs for the AT&T variant and I do not get a prompt to input a network unlock code. I've tried the dial codes (2945*#350#, 2945*#71001#, and 2945*#20001#) to no avail on both the Korean firmware and on the Google Fi one. Since I don't have a way to get back to AT&T firmware, am I out of luck with unlocking this one? Thanks for your time.

Nevermind - found solution on XDA: Insert AT&T card, wait for it to read (does not have to be active) then switch to another carrier's SIM and it asks for the code. Whew!

What worked for me on the V35 - put an AT&T SIM in first then after it reads it, swap in a not accepted one. Network unlock request came right up.

I forgot to mention that I was on the Google Fi / ULM Oreo firmware when I did that.

V350ULM10e_00_NAO_US_OP_0717

If you're on Pie then I doubt you can roll back, but I was on AT&T Oreo update then went to the Fi / Unlocked ULM10e to the Korean KT N10S back to the ULM10e just fine.
