The ribbon cable came with a little plastic piece broken. At first I did not think it would be a big deal, but after replacing the ribbon cable, the phone would shut off after a couple of minuted of use, and give me a computer garbles textDisplay That was frozen on the screen. To get it to turn back on we had to push and hold the power button as if I was trying to go into DFU mode. After a lengthy internet search, I found did the iPhone does this: because of a damaged compass. The plastic piece did what I said what for the broken compass. Makes sense. So re-installed the old ribbon cable with the good and bad compass power button. At least now the phone works properly. I would like to get another ribbon cable sent out.
