I have an issue with my redmi note 4 global version (SD variant). I used an app, hidden android settings to try and tweak the band mode of the phone. This caused my SIM 1 to stop functioning so I tried to flashing it with fastboot ROM. Now the phone detects the SIM card, signal also but I can't make/receive calls and can't dial ussd codes. Please is there anyone that can proffer a solution to this? Thanks
