What's the CB version? Were there any bad blocks in the original NAND dump?

Sorry to reply so late i found out it wasint exploitble.but then im not sure becasue the nand that i dumped had errors on it i dont know if flash tools read the cb correctly .one thing im having major isue with is i duped the nand but didint realise there was errors on it now when i try removing xell the xbox doesint boot up. is there way repairing the nand i tryed using nand healer its giving me error when i try to go for a fix i think it doesint like win7 32bit.could anyone help me repair the nand at least so i can get it to boot up again

how many copies did you get of the original nand?

Did you have any bad blocks?

Did you try and flash a copy of the original nand dump back to the xbox to see if it boots?

First rule when messing with xbox's flash is to check that the dumps are ok before writing anything to the NAND.

I'm not sure if it can be done as I have never had to do it before, but you might be able to. We still need to know the details of your dash/kernel and see if you can extract your KV (encrypted obviously)!!!

Are the info not showing on 360 flash tools?

iv got it sorted thanks for showing interest.Somehow xnand healer must of done the job i just redumped fixed nand to the xbox and it booted up.but there is one questionmark in my head stil.l can a nand with errors show wrong cb version or em i just just wishing something thats not gona come true my jasper showed up cb 6750 not exploitble on the nand with errors ????

The CB will be right and wouldn't be affected by the NAND dump, if it did it simply won't be readable that's all. If you're Jasper MFR date is past 15th June 2009 then it's probably why it's not exploitable.
