Rebuilding Nand With a Donor Nand Dump

[badwolf]

Someone has an idea of how to work with jasper 256 nand? I made two backups of the nand and seem to be ok. but when I turn on the box after restoring my backup I have the error 0022. I already have the cpu key by xell. The problem appeared when I restored the backup. So I think the only way to restore the box is to fix the  nandbackup or create a new one with the proper values.

I want to go back to my origanal dash. I Have a Xenon MFG DATE: 2006-06-21 xbox and did the Free60 hack when it now came out from this tutorial http://xbox-360.logic-sunrise.com/dossiers-et-tutoriaux-40691-after-4-years-waiting-the-360-hack-is-done-without-chip.html. I dump my nand twice and did not get any errors so i thought it was fine so i then flashed the Xenon_hack.bin to my xbox and got the cpu key. When i entered it in flash tool & degraded i got cannot read file. I double checked CPU key and also dumped cpu key from GENTOO with dump32. I got my xbox to power on with V1888 from degraded but got no display and RROD after 20 seconds. I think my pairing data is wrong. Will I be able to downgrade with CYGNOS V2.0.
THANKS

check for bad pages with infectus nand tool!

Hi everyone!
Same problem here. I have a jasper 512mb. My old pc is broken and hdd is dead (i try many times to read this IDE hdd in other pcs, unsuccesfull).

I´m thinking swap this 512mb nand for other 16mb. If i dump this 16mb nand perfectly it´s possible works changing cpu key?


Here´s a pic from Xell:


Thanks in advance and sorry for my english.

just use XBR image cus u dont need pairing data or ldv u will need ur cpu key and a kv file encrypted with the cpu key from ur console! use bincrypt for that

360 flash tool will do everything you need and then some.. took me 3 mins.. recovered a xenon. Extract, patch, import. Lucky me, happy friend:)

Sorry to bump up the thread after months, but I have similar problem to previous posters, and was wondering if anyone has a xenon 1902 1888 cb cd donor nand so I can downgrade.
