Hello, so yesterday I tried to flash custom ROM and it worked perfectly. So I decided to try other ROM and after installing it I didn't get any mobile network. I checked my IMEI and it was 000000. Is there any way to set my IMEI back to previous? I have my previous IMEI in the box, I just need to change it back. Phone is Samsung A5 2017 (A520F). Any help will be appreciated.
