I am not able to fix the issue im having with signal dropping on my Poco F3, even when there is a good signal in my area, im getting an error "SIM card isnt inserted" and it drops all mobile signal (data), i tried to do a format and "clean" install (factory reset & wipe data) but it didnt help, i was looking on how to rollback to the stock Global ROM but either im doing something wrong, or the phone needs a special procedure for it because it didnt do anything (LOL), so im kind of desperate for some help, i never noticed this issue with the global ROM so im thinking about going back but im not sure having TWRP will be an issue or how would i need to flash the stock rom and not bricking my phone in the process, any help will be appreciated.
