Identifying Resistors/Capacitors on the logicboard

Hi!

I bought a damaged iPhone 5s and it looks like somebody already tried to fix it.

He/she installed a new sim card slot (what a mess since he/she used glue!) since

the iPhone 5s has a "searching..." problem. I guess it is the broadband ic, not the sim card reader. Anyway, i replaced the replacement a bit more professional.

I then inspected the pcb and found that some resistors/capacitors are missing. I guess this is the result of "bad soldering skills"^^.

Anyway, the problem is - i dont know the value of these components. I already tried to look the up at a schematic i have, but i looks like the schematic is not complete/correct.

I am looking for the following component:

One or two more parts are missing, but I already know their value ;)

Thank you in advance!

Oy...bad soldering skills indeed...and glue!?!

The iPhone 5S has a few different versions of the logic board. I looked at the 820-3382-A version.

The top component of the two is C103 (56 pF / 6.3V / 5% / package 01005). The bottom component is FL59, a ferrite bead (120 Ohm / 210 mA / package 01005).

Just search Google "iphone 5S schematic", you should find it pretty easily. You can also sign up at GSMHosting, they're pretty much all there. Unionrepair.com also "sells" them.
