[nicomic]

hello everybody,
i'll try to explain what i do but sorry for my english cause i'm french.
i've already dump my xenon nand with lpt and free60 hack, then i find the cpu key with xenon hack and finally i put my nand origin back.
then i play online so i've done the update of the 11 august.
yasterday i wanted to come back to my orig.bin dumped before 11 august but red lights.... then i see we can't downgrade but , what a stupid guy i am, i don't have made a dump of my nand 8955 xenon before flashing it
now i can't reboot my xbox
can someone help me?
i got the cpu key, the kv.bin, the nand before 11 August but i don't know how to do to boot my xbox again
thanks all!!!

With the update, you locked down the console for good. No way to ever launch the xell exploit again.

People were able to rebuild older versions of the flash with the info you have, as long as there isn't anything else added for security it should be possible.

There are a few threads on rebuilding the NAND with different versions, you could try to get it to work for your version, also take a look ath the ldv values.

Good luck
