was slightly water damaged in the middle area on the board, not that bad, it was turning on when it arrived here
- than i put it in ultrasonic
-did not turn on
-after measuring around, seemed basically , so i reflowed the SMC, than it turn on again now,
-i can do SMC reset, nvram reset, there is chima, backlight picture
-i can always go in the boot menu
-it starts from usb stick, or internal hdd, but arund halway of booting just hangs in there and wont go further

yes, i have a good test hdd, just used in another macbook, and i replaced the hdd cable

from usb it actually stuck halfway, on internal hdd it keeps restarting after about 1min of loading, and the line would reach abuot half way

Ughhhh yeah this one will really really suck. If you're for sure, the cable and all the internals are good (battery etc), this could be anything. What is your resistance to ground on PP3v42 with no power applied/battery plugged in?
