My gsm is invalid. I can't call or receive sms. I haven't got signal from sim. I flashed CN Rom to Row Rom because the phone was bricked. I lost imei but I fix it via write sn tool. But signal is still don't working. I lost also serial number. I tried o lot of others Rom but still I have that issue with calling. Can anybody help me who can fix it ? I have lenovo s850 Row s217.

with MTK phones, the stock ROM is the first line of action when fixing signal detection issues (secro.img)
might also be due to using unsupported IMEIs or network settings
