iPad Pro 9.7" A1673 schematic need thanks
I've found the bitmap .PCB file on this forum (although many things are wrong with it, such as inductors labeled as resistors or capacitors), but I can't find the schematic. Can anyone share it? Thanks.

Hello. I came across with the power supply constantly resetting on IPAD A1673.
(I connect it to USB power)
PMU U8100 is rising all voltages except PP3V3_S2 . Consequently, the SYS_ALIVE is also absent.
I have two identical boards with the same symptoms, and I think this is a common problem.
I also have a working board. I've taken all the measurements to compare and haven't seen any abnormalities. There are no signs of a short circuit or water damage.
VREF, IREF are also present.
I also couldn't find any PP3V3_S2 enable signals.
Please help me and suggest... -
I tried searching the forum for whether this has been uploaded already, but couldn't find them (as a collection).
Here's a dump of a bunch of iPads, I've split into 2 archives to get under file limit
