Thats the J-Tag portion of the hack. You don't necessarily need the qsb but the proper connections have to be made.i just whant to know if it is realy need instal the áudio_clamp qsb, or the R-JTAG works fines without it instaled on xbox 360, i mean R-JTAG only with the chip and the POST_OUT QSB with the ribbon cable.. thanks
thanks m8Exactly, but the transistor method is better than the diode method
