[Q] Micromax A311 invalid IMEI unknown Baseband error

[GuestD2576]

Guys yesterday I tried porting MIUI rom from Coolpad F1 8297w to Canvas Nitro A311.
The port was quite successful :good: , so to make it better, i restored my stock rom by TWRP.
But when the phone turned on, it showed an error "Sim card unplugged". I found that on dialing *#06# the IMEI shown was "Invalid IMEI".
Also in Settings/About Phone, the Baseband version showd "Unknown".

Now I am unable to make any calls or use internet. Please help guys.

I tried MTK Droid tools, but it shows "file adb not installed"
I re flashed stock rom by YGDP Tools several time but no solution.:crying:
Now I'm trying IMEI & SN Writer v1.5.3 and it is also not working. Maybe i do not have the database files.

Guys please help me. I know there is a solution to this, afterall, its MTK chipset. But im missing something.
Please provide some solution. Or somebody give me the baseband files of Nitro A311, maybe that will work.
Im about to port a bug less version of MIUI v6 and I will need this to work. So please guys, devs, help me.:crying:
Thank you

New update.
I have fixed the unknown baseband issue. Even the mobile repair shops were unable to do it and were asking for 200 rs.
If anyone wants help in this topic, just comment below.

Fixed this issue

You have to download stock rom in cpb format from needrom.com and have to flash it through ygdp tool and it will resolve your issue
