From russian xbox forum (translated)
I've compared the two dumps (Falkon 8hhh) to disable the installation and after. There is the difference - 1 block of 33 kb. I've restored this unit - installation has been enabled. I've flashed in place of this fragment a similar piece from another console (xenon 7hhh) - Set the game worked again.
I have this piece is to offset 0x586e00 (size 0h8400)
nandpro for this block number 0h157 and 0h158
NandPro lpt:-r16 dif.sec.nand.bin 0x157 2
perhaps it is - just a coincidence.
well, a bit sorted out the deed.
when trying to connect to a live console banned ban flag captures and stores it in a file secdata.bin Nande (naturally shivruya his cpu key).
I have uploaded the file has changed since 11.22.2005 12:00:02 PM, on 11.18.2009 01:21:50 PM.
Moreover Offset file changes too - the file moved from the block 0h155 in block 0h157. but the original in the block 0h155 stayed. (HZ for what purpose, can backup, a feature of the file system or trivial bug)
I podgadil in blocks 0h157 and 0h158 and my box started to use the original secdata.bin of blocks 0h155-0h156. game set, CONy not tied to the console.
all this on my box, on the other boxes, the original copy secdata.bin may not be or have the other files will be Offset.
is in this whole point that I do not know why it worked. and under the arm while no other console with a welded LUT interface.
because of the idea, I overwrote the devil knows that the devil knows what. may not fundamentally than I rewrote it. and do not accidentally hurt anything important.
at the expense of one byte, if the value of ECC correct, then the prefix and does not throw an error if you do not hurt anything important.
