iPhone 5S motherboard missing component! Not turning on.

I got an iPhone 5S logic board but it lost an little resistor near the battery connector and it doesn't turn on and it had water damage but all the corrosion is completely gone for now. The water damage was minimal. It was only near the battery connector. However it doesn't even turn on when battery disconected and only plugged in to charger. Is that normal?

I got macro pictures of it!

Please help me out of the fire!!!!!!

This is the resistor/cap. Is this crucial and can i make a jumper?

Normally that cap is not necessary but if the pad was torn too or one of those caps was shorted it could cause issues. What do you mean "it doesn't even turn on when battery disconected and only plugged in to charger?"

You know, if i plug the phone in to the charger without the battery connected up to the logic board, should it turn on or atleast give an apple logo?

No you can not apply a jumper. that would connect your battery VCC (Positive Supply voltage) to ground and cause a short. Replace it with a 220PF 10V 01005 capacitor.

Oh, one more, is this a crucial capacitor or just for stabilization? And what does this one?

da

It looks like it's used as a smoothing (filter) cap. It is possible that the missing cap is interrupting the circuit. Not sure what you mean with your last question. It looks incomplete :-) "And what does this one?"

Oh, i mean: what does this cap. But it isn't even drawing electricity when on the charger and there is absolutely no life. Could it be the PMIC chip been corrupted?

da

Yes, it could be the PMIC or even the battery connector and lightning port. But, remember that the cap is part of your VCC circuitry from the battery. If the circuit is interrupted you will be without power:-) I would replace it then re-evaluate. At least that way you know that it is not the cap

Basic question: you're using a known good battery?
