My nand was 9199. Some backups give the clean the disk error when loading. That's why I tried to reflashing with the one with the secdata modified. The different berreen kernels give me the three red lights. I have my original nand but the kernel its not what its installed in the box.
what in gods name made you think that the dirty disc error had something to do with the NAND filesystem?
secdata.bin has absolutely nothing to do with whether or not a game loads, you seem to be very very confused or ignorant to what secdata.bin is for.
most likely answer is your laser is on its way out, or else you are using poor media for the backups
the NAND filesystem would have 0% bearing on discs loading in a retail (non Jtagged) console. period.
let this be a lesson to research things 10x before wading in feet first.
Your 360 hacking knowledge is obviously lacking, no offense.
you could try incrementing the LDV values of your original dump to match the ldv's of the fuses on board but i'm not sure if that would work TBH its a long shot.
