Getting DVD Key from NAND dump?

[cagerhager]

I have a RROD that I was not able to bring back but the disc drive is fully functional. However, I was able to dump the NAND as the RROD is gpu related.

I want to put said disc drive in another rgh system I have that has a dead dvd drive but I do not have the DVD key from the rrod console to input into the working system. I know you primarily need to boot to xell to get cpu and dvd key, but is there a way to obtain the dvd key from a nand dump or other means?

You need the drive key from your working system and insert it into the working drive from your rrod console. So you dont need the drive key from your rrod console.

can you expand please? how does one go about this?

 

[godreborn]

yeah, you can. use kv modder to see the dvd key from a nand dump.

 

[cagerhager]

Thank you. Appreciate the help

you do need your cpu key though to decrypt the nand dump.

so how would you go about getting that. was able to get the nand but since it's gpu rrod is there another way to obtain it?

 

[godreborn]

only through xell or dashlaunch, so the system has to function, at least for a short time.

well shit. so essentially if it rrod gpu, is there a way to put xell to pull it?

 

[godreborn]

how did you get a nand dump?

 

[godreborn]

if you have the kv somehow, that's all you need.

 

[cagerhager]

I was able to read the nand with my pico. guess since the cpu is intact, that's what you need in order to read the nand. I used jrunner to extract the nand and have the kv_en.bin file. is that what I need?

 

[godreborn]

see if it read in kv modder. it can be encrypted or decrypted, but I think in order to decrypt it, you need the cpu key (not sure if both kv and nand are encrypted or both). that's beyond my knowledge.

 

[godreborn]

jrunner may be able to do this, but I don't use that.

 

[godreborn]

okay, I just checked. if it's decrypted, you don't need the cpu key.

when trying to select "open kv encrypted" or "extract kv from nand" it immediately pops with error asking for cpu key. I'm using keyvault v1g

 

[godreborn]

did you try it with decrypted kv? you won't need it if it's decrypted.

 

[cagerhager]

how do you decrypt kv? seems most posts i've read say ya need the cd key to decrypt

 

[godreborn]

that en probably stands for "encrypted." I had to use my cpu key to decrypt it, which it's probably too late to get.

that's what I'm mostly seeing, need the cpu key to decrypt to get the rest of the information.
