Has anyone made a set, soldered a pair pf long sewing needles (don't laugh) ontp the ends of the probe ends?
There is nothing to laugh about it here , in fact the way you proposed is the only way to go about it, solder those needles there you have it !
Also what values should i be looking for resistance wise (non powered board), what should i be testing against??
there you go

also if you want to test the voltage, just power the board using a normal S9 controller , someone mentioned it does pretty much what the tool in the video does, also reading the kernel log, and checking how many chips are shown,should give you a clear signal of which chip/chips to test.
below is a diagram that shows signal flow between the chips
Code:
Green : CLK
Orange: TX
Yellow : RX
Orange: TX
Yellow : RX
Good luck.
