iPhone 6 PMIC toggle voltages (PMIC permanently ON / OFF all voltages)
Hi @refectio !
Some time in my life i have seen iPhone 5s, iPhone 6 or 6plus water damaged or after MESON and CUMULUS repair which do not turn on. After measure voltages i have seen, that PMIC permanently toggle all outputs voltages. PP_CPU, PP_1V8 ...
After measure i found, than also line RESET_1V8_L is permanently ON and OFF.
Where can be problem? Last month i overheated two phones (iPhone 5s and iPhone 6plus) when i want replace MESON and CUMULUS.
I founted video on youtub with same issue. To this day i do not found any solution.

I've got the same behaviour on an iP5... After PMIC replacement on a water damaged iP. What is the toggle frequency? I need to measure mine accuratly but I would say 0.2 Hz
