iPhone 6 water damage -Bootloop -PMIC Hot
Hello,
i ve got a Iphone 6 I bought it with the discription it is failing to restore . So i tried my luck with FoneLab. As soon as you plug the cable in it goes in recovery mode, so i restored it. After restoring it was caught in a bootloop (black... apple logo... black ...applelogo).
So i took a look at the inside (probably a little late). And there it is waterdamage indicators red.
First of all i took the pcb out and had a look than i removed the shields and cleaned it with a ultrasonic cleaner (a cheap one) and alcohol.
Tried it again to restore it. Looks better. goes into the install home screen. The thing is the touchscreen works but the home, power and volume button doesnt work.
I tried a other screen assemply same thing.
thna i noticed the PMIC is getting incredible hot.
I messured for shorts on the main power lines - All good
I messured the voltages of those
- PP5V0_USB 4,9V
- PP_BATT_VCC 4,09V
- PP_VCC_MAIN 3,79V (when i unplug the akku its up to 4,25V, but the akku should be good)
I messured all voltages from the PMIC and its missing PP_GPU, PP3V0_ACC and PP_VAR_SOC is just 0,84V(should be 1v?).
The software works fine now. So i need some help with the hardware? Thanks
