Dear Mahi20015
As you can see in software log phone info
Blank .. if phone info blank baseband is unknown

So first you need to flash your device
With different firmwares untill you get baseband the you can repair imei

Even after flashing if you don't get baseband
That means hardware Emmc issue need to replace or try to repair with Emmc tools
Like easy jtag etc.....!!!!

Till that you get same error with all the professional tools
Hope you got it
