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 Update (05.04.2018) Tried another lightning connector still the same But i found this filter FL2024 its almost broken of the board but still has his connections. i will change this one but do you think thats the problem?

If the PMIC is getting super hot and there are no apparent shorts on the output (you did say you tested them all, right?), then consider running the device in bare-board mode. Remove the logic board, connect a known-good Lightning port flex and battery (preferably different ones) and then boot the board by connecting an iTunes enabled computer. Check to see if it is getting hot and see how long the battery lasts. Then put the logic board back in the housing and start adding peripherals (Lightning, cameras, sensors, button flexes etc) one at a time and verify. There’s a good possibility that one of the peripherals is dragging the system down.

have you checked PP3V0_NAND for a short
