Huh, i saw several posts saying that the internal memory of your jasper xbox is the size of the nand. i made 2 dumps with DemonToolbox and loaded them in J Runner, and it turned out to be a 512mb Chip. Well now that explains why J Runner kept crashing when i was comparing the nands and got the "Header is wrong" error. Oh well, all is good! N00b question but now that i have the nands do i "Create Xell Reloaded" and flash the original OR do i write that nand to my Demon so i do not compromise my 360 of XBL? Sorry for all the questions, sort of new to the RGH scene and have only done simple mods like Flashing the DVD Drive, softmodding Wii's, jailbreaking iOS devices and rooting android devices.
