How to troubleshoot dead iPhone 5c?
I was removing the battery connector from my iPhone 5c but instead using a plastic pry I accidentally used a metallic one.
It sparkled and phone died right away. I think I did a short circuit between the battery connector and the metal shield beside it.
Now my phone is dead and wont power on. iTunes doesn't recognize it and battery is charged (I measure it with multimeter and its about 4,14V).
I want to know how to get started by testing the components to find the damaged ones and replace them myself. Is there any idea?
I took a better look and seems a component is missing between the connector and the shield, it is C22.

What does this capacitor do? In the schematic is 56PF connected to PP_BATT_VCC, is it a filter to the main power bus? if yes, could it be the problem?
Is this a good question?
