IMEI Problem

[Sax]

Pls I have a tecno m3 whose screen broke so I took it for repairs, after the engineer fixed the screen he upgraded the OS to kitkat 4.4.2 and now the phone IMEI is reading as unknown. I can't browse or do anything with the phone though there is network on it. 
What should I do pls. 
Thanks.

check the pics @ https://forum.hovatek.com/thread-311.html and let me know if your M3 4.2 was old or new OS.
Hint: Before the 'upgrade', did it used to write Smartlife when you boot or not?

It doesn't write smart life when I boot, I guess it must be running on the old OS.
