Touch screen only work after restoring
I have an iphone 3G.
Well the touch screen doesn't work anymore.
I replaced it and it still doesn't work.
Now what i did, was that I put the logic board in another iphone and restored it. and then it worked!
But when I changed the logic board back in my iphone, it isn't working anymore.
I did this 2 times, its really strange,
My first toughts were that connector 2 is broken, but now i'm not shure anymore.
Now i'm thinking that it is a software related problem?
I restored back to original iphone firmware (4.2.1).
Can someone please help me?
