Both ports go to 5.12V 120mA and then 5V 0A and cycle again. All diode readings around both cd3217 are basically perfect. Reflowed them and swapped UF260 as I was guessing some sort of comm issue. I think the Mac goes into DFU when trying but is not detecting through the ports/showing on configurator. Thought about changing cd3217's but they both act exactly the same and perfect readings around them so that would be waste of time.

water spill. couple spots that I could see appear unaffected and in areas not related to problem. I tried dfu with jumper switch also.

No. I recovered the data by network file sharing. Now it no longer booted I’m guessing stuck in recovery from trying to dfu? Or maybe battery is drained? I don’t think that’s the case though. Or maybe I was lucky it seemed it mustve detect charger enough to activate the battery.
