ok i was on pg 5 doing a catch up when i posted.
has told you countless times the TH3301 then see if it boots.
mr.dutch is asking this so you dont need to de-solder and remove the usb ports.
by doing this you can boot and if it boots propperly then its the ports if it dosent boot then its a fault further along the board.

just wanted to check your multi meter was giving correct readings.
and bat sounds ok shorting wise (it would have been a 0.0v / -0.1v if the bat had blown and was now shorting.
the part i have put in red.
this is +5v and ground shorting on that port.
can you give a good clear shot inside that port (look at playerkp420's pics to see what i mean)
and do the TH3301 removal as mr.dutch has said
