I have tried several tutorials I can find on Hovatek forum,  on how to fix  Unknown Baseband and null imei on Infinix X690b.. Sadly  none of them worked for me

I managed to locate this file path
/mnt/vendor/nvdata/md/NVRAM

Which is supposed to be where the phone imei and other important files are located. But what ever I did there got undone after I reboot the phone.

I have also tried to use several of the imei software recommended by hovatek, but my phone couldn't be detected by those software.  Which is surprising cos SP flash tool, auth bypass and co worked perfectly well. 

I am using my phone's USB cord  to connect to pc, I don't if that could be the reason those imei software could not detect my phone.. despite some flash tool and auth bypass detected my phone easily. 


If you know how I can fix this imei issues, unknown baseband and make my phone detect sim card again.. pls help me

Ever since I did that factory reset, sim card stopped working and Baseband became unknown. 
I didn't make any  backup before I did factory reset on my phone.


Pls help. 
My phone building number 

X690B-H691DE-Q-GL-220215V356

It is rooted and bootloader is unlocked.

First you need to fix baseband before you even talk of fixing IMEI.
How did unknown baseband happen?

How did unknown baseband happen?

I did ordinary factory reset, (from phone settings)

After the factory reset., the phone stopped detecting sim card instantly. 

I took it to a phone repair shop and they saw the unknown Baseband and null imei. (Which I didn't even notice)

I took the phone back and started looking for solutions online

Flash back factory firmware first to fix baseband.

I have flashed stock rom with both sp flash tool and mtk client, and baseband isn't fixed. 
but when i ran this fastboot command, fastboot getvar all, my device's baseband was detected as

(bootloader) version-baseband: MOLY.LR12A.R3.MP.V94.4.P48

is there a way I can write it back?

and also, I noticed the phone doesn't boot into meta.. but boots into other modes like Brom and preloader.

how do i fix this?

Install Droid Hardware Info. Does it show baseband?

I used this command (adb getvar all) or something like that.. and it showed the baseand number. 

But droid info is saying unknown
