1-2-3-4 pads of J1D2 are for spi port.
the signal (or voltage) 4.J1D2 is 3.3 volt but in my console is 0 volt.(1-2-3-5-6 havent problem).(second file-->> 14 page)
1-2-3.J1D2 are southbridge input and 4.J1D2 is southbridge output.(first file-->>35 page)
i tested the R1R1 resistor.its healthy.
whit this in mind the SB or part of SB is damaged.

You can either replace the southbridge or if the console still works, just use another device to read/write to the NAND directly (cygnos/infectus/progskeet etc).

if using another device to read/write to the nand as per quote do these power nand without having to plug power lead into xbox ?

Most devices require a standby voltage to the NAND in order to work.

thanks martin for reply.was looking at progskeet (ps3) and seen the 360 clip that sits over nand.had posted couple of months ago and you had machine with similar problem (http://team-xecuter.com/forums/showthread.php?p=523938#post523938)did you come across a solution for yours ?
