Liquid damage on 3023 Board

[WiFiComputers]

As soon as I plugged battery to Motherboard, Chip U6990 at Pin 6 Sparked and chip dies
Replaced Already U6900 and D6905 , but still Noticed Resisteance at PPVIN_G3H_P3V42G3H at Pin 6 is 100Ohm only
Removed capacitor C6999 and C6990 but still low resistance.
Don't understand what should I try Next

Didn't tell us what happens with charger only...

Did you check resistance to ground without U6990?
Also check it on L6995 too.
Be sure R6995/96 are both good.
