I have a XQ-AT72 which is China version with 12GB RAM. Tried to flash firmware of Japan (AT42) with newflasher but it resulted in my device being corrupted. After that, I flash the AT72 rom again but no help. Anyone succeeded on flashing customized firmware on this variant of 1ii?

Now I successfully loaded the firmware of SEA to my phone, it can detect SIM card but there is no signal. Does anyone know which file in the firmware is the modem file? I will try copy it to the rom and flash again. Thanks.
