found this in one of the tuts I didnt see before
X = 5, 6, 7, 8 or 9 (depending on what dash you have/when your console was made).
now search in hex for "CB" (without quotes) your looking for the one at or around 8400 in hex (it has to be in caps).
copy the 4 hex digits after it and convert it from hex to dec with this Conveter

Xenon: 1921 or lower is Exploitable (exception: 8192 IS EXPLOITABLE)
Zephyr: 4558 or lower is Exploitable (exception: 4580 IS EXPLOITABLE)
Falcon: 5770 or lower is Exploitable
Jasper 16mb: 6712 or lower is Exploitable
Jasper Arcade (256/512): 6723 or lower is Exploitable
so I think i did it
8400 reads 43 42 1a (CB highlights 43) 4 digits after are 42 1a converts to 6626 but I need to know for sure im looking at the right numbers
never was much on hex editing etc
well answered my own question seems i was doing it wrong found cdinfo finally in a tool pack also updated 360 flashdump tool that reads it
cb = 6712
so with hex iditor i had 8400 43 42 1a 38 i guess the 1a38 was the cb
as stated hate hex
