iPhone 6 Stuck Itunes Logo (Error -1)

Hye i got an IPhone 6 sent in to me for repair. It stuck on Itunes logo and when I do recovery it showing Error -1. Before this the phone having a NO SERVICE issue, and then when the customer do recovery on itunes, it begin to stuck on itunes logo. When I hunt around the baseband area through microscope, I see two caps are missing (C4103/C4104) . I believe that this two caps are responsible for WTR_TX_OUT line.

So my question is, can I just make a jumper on this two lines without solder a new caps ?

You can't jumper capacitors, that's not how they work. These particular caps are used inline, that means they are meant to filter out any DC component to the AC signal going into U_2GPARF. These are pretty standard capacitors and easy to source as new or from donor boards.

Do you believe these capacitors were removed by another tech or were physically damaged? Check closely to see if anything else is missing. As for Error 1, I would reball the baseband CPU.

I dont think the caps is been removed. Maybe because of the physical damaged. So what about the BB PMIC ? Do I need to reball ?

Start with just the BB CPU.
