Hello team hostel,i flash successfully my Itel A31,but it has invalid imei now. I tried to install MTK Engineering Mode,but I can't find CDS information in the Connectivity. What should I do?

Have you checked if you have a valid baseband, by going to settings _ About phone, if yes then follow:

If baseband is invalid you have to reflash another stock ROM.

I have baseband,IMEI but no network

which method did you use to fix imei?
can you confirm if the device is able to receive network while on 2G only network mode?
have you tried flashing nvram? download @ https://www.hovatek.com/forum/thread-21189.html

tried to flash nvram or you were able to flash the nvram successfully?
if you were successful but still get no network, then you need to look for a working device with same model as yours to backup nvram from

Flashed the nvram successfully,but still the same. Where i am is impossible to get the same working model.
If anyone who have this Itel A31 (A31-I803-7.0-OP-V026-20170717) nvram back up,i will appreciate if he share with us.
