Does anyone know the chip part number or pinout of the two 4-pin chips on the bottom right of the motherboard as seen in the Step 14 picture? My deduction is that these chips control the power on / off and volume. My issue is that I am repairing the screen and ordered a replacement that includes screen+frame. In that assembly, the orange ribbon cable as seen on the left side of the bottom case view in the Step 16 is not included. So when the phone is all put together, it will not power one as there is nothing to make contact with these chips. The replacement screens do not seem to have this needed piece. I am thinking I can solder some wires to those pins an short them as needed to make the power / volume functions. My goal is to just get the phone powered with the new screen enough to get the data off the phone, so rigging the wires this way may work. I just need to know the pinout on those chips.
Once they have, you'll be able to view a graph of their reputation gained over time.
Here's a preview of what the graph will look like:
