Recover cpu key without nand

Hi.

I received a console that got screwed up during a glitch attempt.
The guy told me he was doing his console and a friend's console but when he was trying to read his nand, he instead flashed the initial part of his friend's nand because he had some batch files that he confused or whatever...
SO yeah, the smc and kv of that console is gone and he doesn't have a nand dump.

I know that on the JTAGs one could just flash xell, recover the cpu key and rebuild the nand. Can something like that be done on the RGH?
I've tried doing the glitch by using another console's image00000000.bin (same motherboard version) but it just sits there without booting.

The console is a jasper, btw.

That's the thing. I don't have a valid image because it was partially written over on the board.
The guy had a batch file that read the nand and another one that wrote the nand. He pressed the one that wrote into the nand some other image he had laying around on the same directory and that overwrote the initial part of the console's nand thus erasing the smc and kv sectors.

I used some other console's nand to generate the ecc (same board revision) but it won't work like that... I was hoping there was something that could be done to generate some working ecc for this console just in order to boot to xell and retrieve the cpu key.

Really?

Even with the RGH? I'm going to try it tomorrow and i'll get back.
Actually i've already tried that but maybe the donor nand i used had a different CB so that's why it didn't boot...

Ok it worked.

I have my cpu key but now the thing is, i can't rebuild the nand on multibuilder 0.7.

It says it wasn't able to decrypt KV although i've already edited my donor nand's kv and can open it on 360flashtool (i can read the dvdkey, serial nº, etc).

Any hints?

Yep.
I've flashed numerous consoles before i know how the whole process works.

This console, however, is giving me a pain in the ass...
Now it developed a bad block on address 1. F*** me!

Now it's giving me an error on xell that states "SFCX error something something. Please worry!"

If someone would be so kind to generate a nand for me, that would rock! I can share the cpu key, no problem there as i really don't care.

The console is a jasper CB 6750 and has developed a badblock on the very first block.
It has ldv6.

Any candidates for the nand generation please post here and i will PM you with the key.

Thank you so much!
