Xiaomi Redmi Note 8 Pro

Hello,

Recieved an Xiaomi Readmi Note 8 Pro water damaged phone. Removed all the shields and cleaned the board with ultrasonic cleaner.

1) Found out that VSYS line was shorted out (Found the badboy on the motherboard and removed) now VSYS is showings correct voltages.

After i put the phone to charger it is showing fluctuating "Amps" 0,15 till 0,48 and still cant be booted.

Voltages from some measured capacitors are going up and down continuously.

Hi @kapuzta

I don't know the answer but here's a link to the schematics for the phone that may help to find out what's going on. Apologies if you already have them.
