I have Lenovo S850. A month ago, it showed firmware upgrade and I did it but unfortunately the update didn�t went successful. So I asked help form a local technician. He could bring my phone to normal condition but the following problems were appeared:
IMEI: invalid
Network: Unknown
Signal Strength: 0dBm 99asu
SN : 00000000
WLAN MAC address: Unavailable
IP address: Unavailable
Bluetooth address: Unavailable
Shows NVRAM WARNING: Err = 0x10 ( but could be connected to other wireless networks)

However, Model number, android version, baseband version and build number are known.
I tried Engineering method to write IMEI and I was successful to restore my IMEI however it still couldn�t identify network signal.
I thought to create thread in Hovatek and created account but my account was however not activated.

I beg help from Hovatek.
I hope getting reply soon.
Thank You Hovatek

can you get access to another lenovo s850 without all this issues?
OR you can try restoring this nvram backup @ https://mega.nz/#!YjwGDCKD!6mIkmEJlk3FGn...Pgas6Tb1i0

I can't access to another Lenovo S580 because everyone are Samsung Users in my locality. So I'll try restoring the nvram backup as you suggested.

You'll flash this using scatter file and SP Flash tool.
Have you tried using GSM Alladin, Maui Meta or SN Writer @ https://www.hovatek.com/forum/thread-116.html ?

I tried to use GSM Alladin Method but an error occured during disabling signature verification. So the complete process couldn't be carried out.
Similar for Maui Meta. But while Using SN Writer I couldn't find the required db files.
And what is meant by scatter files?
Please help me.

you can find scatter file within the stock rom of your device, since you dont have it then here is what you can try
backup the firmware of your device in scatter file format using the guide @ https://www.hovatek.com/forum/thread-13347.html
once you are done, create a new folder in your desktop named Hovatek
copy only the scatter file from the backup folder into the hovatek folder
then copy the nvram.img file into the hovatek folder
rename the nvram.img file to nvram.bin
there should be only two files within the Hovatek folder now
flash the nvram.bin file within the hovatek folder using the guide @ https://www.hovatek.com/forum/thread-14106.html
