A few weeks ago our new puppy decided to " taste " my S3, cracking the screen in the process. I eventually bit the bullet and bought a screen kit to fix it, However in the process the puppy jumped up and i ended up destroying my actual LCD. So today I bought a phone that had been barred with the idea of putting my mainboard into it to get my phone working.
I know my phone was ok in the old housing ( albeit with no screen as i could call it and had the blue flashing light when getting an SMS ) however as soon as I put it with the new screen I had no signal and when i check the networks it says insert sim card to access network services.. Also when i ran sim unlock it says my IMEI is null
I also have this on my phone every time I start it...
I have an EFS back up but I have no idea on how to restore it could some one please help.
