I have an AT&T LG G8 ThinQ LMG820UM running Android 11. I wanna know if I crossflash an Open_CA firmware/ROM onto it, would it work with the VoLTE on AT&T's network without having to call AT&T to disable the 3G blocker? Does anyone have personal experience with this?

I would like to install the Korean (specifically SK Telecom model) variant of the firmware, the F400S, on my AT&T G3, the D850.
Reason I ask is because I brought my AT&T G3 phone to Korea and was able to get on SK Telecom's network. But little quirks like not being able to use hotspot tethering, visual voicemail, and access to SK Telecom specific appstore is becoming a hassle.
Would it be advisable to flash my D850 with F400S firmware? Anyone ever tried this or have any insight into this matter?
Much appreciate it. Thanks.

Possibly stupid question from a novice. I have a G7 ThinQ (LM-G710VM) which I bought from Verizon. I switched to Mint Mobile (uses T-Mobile towers) and need to use Wi-Fi Calling due to signal strength issues. Mint Wi-Fi calling doesn't work on the Verizon version of the phone. Is it possible to load the T-Mobile firmware on this phone? Or the LG Stock Firmware? If so, could someone point me to a thread that discusses this. I've been unable to find the right one if it exists. Thanks in advance for your patience and help.
You should look at changing your VoLTE settings possibly. As for easy crossflashing of firmware, I did this last night and it is simple, no need to unlock bootloader etc. Only issue is it does not do t-mobile, but a generic rom may work.
