No liquid damage, just stop work.
  • PPBUS_G3H = 8V
  • PP3V42_G3H = 3.4V
  • PPVRTC_G3H = 3.4V
  • PP5V_S5 = 0V
  • PM_SLP_S4_L = 0V
  • SYS_ONEWIRE = 3.4V
  • 3V3_SUS = 0V
  • U7501 PIN 4 = 0v
  • U7501 PIN 23 = 8V
  • PM_SLP_S5_L = 0V
  • PM_SLP_S4_L = 0V
  • SMC_ONOFF_L = 3.4V
  • PM_BATLOW_L = 0.4V
  • C7524 = OK

"PPBUS_G3H = 8V"
I bet for 8.2V; post exact value next time!

"PM_BATLOW_L = 0.4V"
The board cannot start.
Be sure to have correct charger.

First of all, SMC_RESET_L?

No communication between SMC and ISL6259.
Post voltage and diode mode to ground on SCL/SDA lines of battery bus.
Also try known good LIO board/flex.
