AXP228 chip over heats

My A06 uConsole suddenly decided it would stop powering on. Opened up up and everything seemed normal visually. Measured 3.71v on each battery, plugged in USB-C, and attempted to boot. No green led, but usb-c cable was getting warm and could feel heat through the A06 board. Unplugged, pulled A06 board and replugged in usb-c → AXP228 chip was getting extremely hot, aka can’t leave finger on it. Immediately unplugged power.

Nothing happens when press power switch on batteries only.

Next steps? Thinking I need a new mainboard?

It seems to have also nuked my SD card.

It’s a shorted one. It seems to be a typical symptom in a defected chip.
