Why Is My Phone Stuck on Boot Loop After Liquid Damage?

Hi, first of all I would like to say I'm not looking for simple answers, i.e - hard reset, disconnect / reconnect battery. I would like to know if anyone out there, all be a technical genius could answer my question and give me some pointers. Now I'm no professional at phone repairs but I've done a fair few to understand the basics. I've never done any IC soldering / repair nor can I due to lack of equipment.

Basically, my question is this: Why is my iPhone 6 stuck on a boot loop when plugged into mains power but will not turn on independently via usb to pc or by it's own battery (new battery). The phone I believe has suffered water damage and after inspecting the pcb I noticed a scorch mark on the lower part of the board's shield. I have no idea what IC's to look at or what areas to look at first.

I've noticed that some of those IC's have suffered some damage and I believe maybe some of the board's ceramic caps are missing / damaged. I only have a soldering iron and a conventional multimeter, so any starting point would be good.

Any information regarding that would be great. Thanks.

ok brandon your phone can bootloop with shorted components but finding the actual component can be difficult if you don't have a dc power supply. i suggest you take a look at the capacitor to the left of the wifi chip even if you knock it of the phone will still work

Thanks. Do you by any chance know where I can find a diagram / schematic of the iPhone 6 logic board? I don't know where what IC's sit where.

possibly a zxw file type from gsmforum
