That is my first post.. soo hello I have problem with my iphone 5s - after drop I changed display, but phone not turn on... change battery and launched, but in DFU mode. iTunes see phone, but when I make recovery soft she load to end of the bar and crashes error... I forgot the code because put down iphone with a lack of time. Now when I back to repair he again not starting - I connecting to loader and left on three hours but no avail... grrr. I check voltages on port battery [power via usb-pc]. 1 pin is GND, 2 pin 0.05v, 3 pin 0.50v. Battery has 1 pin GND, 2 pin 2.50 and 3 pin 0.08v why she will not charge? My next question will turn on phone in normal mode, but first I must check why not charge.
