Replaced IC chips and Now have this issue.

Hey Team,

I got the touch Ic chips replaced on my iphone 6plus, the camera and the wireless stopped working because the first repair shop apparently melted the board and ruined the connection

Then the phone would randomly flicker and come back and then flicker again to a point where i would need to firmly press on the top right of the screen and let go for the screen to come back from the dead.

I got the screen replaced aswell to see if that would fix the problem, but the problem came back after a few hours or when the phone would heat up it would start to lose its legs.

Then the phone start to randomly flash the apple logo when it felt like it, but it would come back when it wanted. So i could still use the phone but not at times i wanted to.

I got the battery replaced to see if that was the cause of the problem, but knowing my luck it was not.

Now the phone is in full Restore mode, no program can get it out, switching it on and off/ Hard reset, nothing has worked.

Its stuck on the apple Cable >> Itunes Screen. Is there a solution for this problem? Can i fix another part on the phone or is this it?

The guy at the phone shop actually said i dont know how this phones working but it is. I mean all the other parts on the phone are brand new, its the mainboard that has seen damage from phone shops stating they can fix the problem without using micro soldering and trying to cheat me.

Thank you for your time
