Currently selling a broken JTAG, Now i don't know what the problem is, But last time i checked, It looks to be the 3rd or 4th quadrant of the RF board, However the RF board is not going on at all :P.

Xbox is still booting, and i'm guessing all it needs is a reflow, Still i'm open to any offers, £20+, Pictures are available on request.

EDIT - Just tried it after over heating, Confirmed the box goes on :)
