Install Stock G7 ThinQ on Verizon G7 ThinQ

[mpk6605]

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.
