Credit goes to Jessa at iPad Rehab, made a summary below of video:
PP3V0_ACC (From U2 Tristar chip [ACC_PWR], Pad D5 is location of it under chip) is used for powering lightning accessories (usb fan / HDMI adaptor / unusual stuff) from the lightning dock connector.
Phone will still charge normally without PP3V0_ACC with iPad / iPhone wall chargers and USB connection to computer still works.

Below is potential solution from a GSMhosting thread
For PP1V1_GPU short it could be caused by U7 (Power Management chip)
Removing l13 and l14 I assume can be used to confirm if U7 is causing short.

Edit forgot to say with PP3V0_ACC missing the phone will charge half speed if a USB ammeter is used. 0.9ish-1.0 Amp is expected charging speed for normal charging.

Hi Ben,
Thanks for a quick response. I found out already that PP3V0_ACC does not impact charging but does it affect boot or when trying to restore? Since PP3V0_ACC and PP1V1_GPU are created by PMIC I probably should suspect it first?
