Hello guys Here I have strange question. I got iphone 5 with U16 ic missing. It won’t restore and it won’t work with new lcds. I tried to install new LCD (few of them)and is not working with any other than the LCD that is with. Also when I try to restore comes back with error 4005, 4015 or it just stay on apple logo and little spinning circle that is frozen. Any ideas appreciated. Thank you
U16 is the compass IC. It is connected to the CPU so perhaps the phone won’t start unless it is present. Can you clarify if the phone works normally with the original screen but not any replacements? Have you replaced U16 or verified if any other components are missing? Perhaps your PP1V8 line is damaged.
