After trying to do the new hardware unlock, I have succesfully opened the iphone till page 5.

After trying to open the metal shield above the baseband chips, as stated here:

It did not yet open up, but now my iphone doesn't load if I put it in USB. And my touchescreen and button at bottom doesn't work. If i plug the case cable back in it, my power button works perfectely.

Does somebody know how I can get touchescreen etc working?!
