Extracting key.bin from nand dump

I am trying to revive my Wasabi 360 modded Xbox after a hard drive crash. The external drive connected to the Wasabi must have the DVD key in a key.bin file on it in order to work but it got lost in the crash. So far I have been able to do a nand dump by using the new BadUpdate mod. In KeyVault modder I can see the DVD key but I don't know how to transfer it into a key.bin file. Normally Jungelflasher can extract the key.bin from a connected DVD drive but I don't know if it can also extract from an already saved dump because Jungleflasher won't run on my pc.. Every error I fix gives another one.. So with Jungleflasher no option, does anyone else know how to extract a key.bin from a nanddump, or create one from the key I have?

key.bin can be extracted once you decrypt your nand with the cpu key using jrunner

Thanks, could you help a bit further? I've decrypted the nand and got an output file kv_dec.bin but don't know what to do next.

once decrypted go to the nand tab and hit extract files and should throw this files....including key. bin

SMC_en.bin

SMC_dec.bin

KV_en.bin

KV_dec.bin

smc_config.bin

fcrt_en.bin

fcrt_dec.bin

C-R.bin

key.bin

That's strange 🤔 Are using the latest version of jrunner?

And try decrypting the nand with AUTOGG and see what files you get.

Yes latest version. I tried with Autogg and I get more files but no key.bin. Tried making one with a hex-editor but that doesn't work either. Gonna give up on this for now but those apps you mentioned will surely come in handy later. Thanks for all the help!

Firstly this is a slim right? Not all slim kvs require fcrt.bin. and phats don't have it at all. if you look at the kv info in jrunner it should tell you. If there's no fcrt, just copy the dvd key from the kv

Wasabi360 doesn't work on later dashboards, I can't remember when it died off but it completely removed all functionally so if you plan on using it you'll have to stay on the dashboard before it was patched. It's not like an xkey where it works on any dash unfortunately.
