You should know the MTK Baseband (radio) is controlled by the NVRAM which you can find in data/nvram/md/NVRAM/NVD_IMEI and a file called MP0B_001.
If this file is corrupted / Missing, your IMEI will be gone and you cant connect anymore. I will be providing a download link to my NVRAM BACKUP that works with all MTK DEVICES such as e.g TECNO, GIONEE, INFINIX E.T.C

   There are many reasons your phone NVRAM can be corrupted. If you like tweaking your phone and installing custom roms you should backup your phone Nvram sector in a very different folder. A full rom backup is not enough because most of the time, it won't backup your Nvram. In this post i will be providing a solution on how to repair a corrupted phone NVRAM and also repair your IMEI using MTKdroidTools on your pc.

A Corrupted or deleted NVRAM can cause problems like:

 1.WiFi related issue and your phone shows “NVRAM WARNING err 0x10” massage in the notification-bar.
2.You will get "NVRAM WARNING: Err=0x10" when you search for other wireless devices, and Even when you see your wireless router and connect to it, it keeps disconnecting.
3.Not detecting SIM card
4.No imei and baseband;
5.Even after restoring the imei using MTK DROID TOOLS, it still do not get network signal.

HOW TO REPAIR OR RESTORE YOUR PHONE NVRAM EVEN IF YOU DON'T BACKUP

STEP 1 : Download the NVRAM BACKUP HERE
STEP 2: Download MTK droid tools HERE
STEP 3 : Enable USB Debugging on your Android Device. To enable USB debugging: Open Settings > About Phone > Built Number (Tap on it for 5-8 times). Now, Again go to the Settings > Developer Option > USB Debugging > Tick to Enable.
