Hello
I have got A1990 that not starting, and was stuck on 5v, and i had no PPBUS_G3H, i got to replace the U7000 and now i have PPBUS_G3H.
I can take the computer to DFU mode but the restoring can not finish its job.
By the way i have 20v right now.
I measured some more and find out that:
PP1V8_G3S is 0v
PP5V_G3S is not fix and jumping between 2.5 - 5v.
May i have some advices, I can not find the problem and i do not know where these power creates.
On the USB_C meter the arrow some times show toward the computer and some times are against. and no amp.
