you flashed the modem, find the right firmware to flash back

It's not about allowed or not as far as I am concerned - it's about directing questions to those who can answer them

the modem is
Quectel RM520N-GL if that helps i'm sure it's to do with AT commands who do i ask about this?

Which firmware do you have? The vendor sends me the firmware; if you want to try it, let me know.

Please get in contact with ZBT then.
