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!

I did it too ...with stylo 4 from at&t lm-q710wa i flashed a canadian firm to frp bypass now i cant get back ...cant find at&t firmware to put network code... do you found solution?

You will not find it, AT&T firmware are not available anywhere.

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.

Not worked for me

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

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.
