logic board wont power on damaged circuit behind sim tray?
Hi, While rebuilding my own iphone 5, 16gb GSM yet again after i replaced the charging dock and battery a few times,I can't seem to power on my device. I have noticed via pictures of the iPhone 5 logic board on web compared to mine that the section behind the sim tray on the logic board is completely damaged. I'm unaware how this could of happened as when placing the flex cables it is always a gentle job.
Would somebody explain what this section does, is this the problem to my power? i am pretty sure it's been like this for a couple of weeks, and before the phone would turn on randomly when you leave it plugged into the wall or usb it would display a red battery charging indicator then turn itself off again at random times.
I would like to know is there any possible solution to get this fixed, even if it requires trying to solder it myself as i have nothing to lose at this point..
this is the diagram of it from the iPhone 5 schematic document which i am still trying to understand and hope what i'm thinking is wrong..
any help would be extremely grateful as i cant afford a new phone right now and I've been without a phone for a few weeks now. :(
Is this a good question?
