Xbox 360 unbrick help

The main problem with XBOX 360 is the link between motherboard and DVD drive.

If you don"t have the DVD-key, you can not use the 360.

You can unbrick the bad drive by dumping the Flash ROM with adequate hardware, you need to remove epoxy and desolder the chip. Willem programmer could dump the SST flash.

After that you will have to check if the SST rom contains the DVDKey. If the SST flash is fully corrupted (FFFFFFF...) you cannot get the key and you cannot use your 360.

Actually we can't get the DVD key from the Nand, because the Nand is encrypted with a CPU Key.

 

Sorry to go OT here, but that is very nice of you to try to hook up your buddy with a 360 for free. Wish i had friends like you, all my buddies ( with an exception or 2) are assholes.

 

If only more people thought like that :clap:

 

Isnt that the truth.

 

The patching tools for the hitachi drives dont touch the box key thats held in the firmware so if you dump the SST chip on the PCB you should be able to retrieve the key quite trivially, how are you soldering skills?

 

As long as he didnt try to write to the firmware and succeed then the firmware should still be intact on the drives board.

Remove the epoxy on the Chip and Connect the passkey and you should be able to get the key. Or Use a programmer and get it manually.

Hitachi 79FLs are a bitch to be honest, but theyve become easier to flash.

 

So? It's easy to decrypt.

 

Do you know a way to get the cpu key directly from the encrypted nand ?

 

There is no way to do that I believe, and even with a working DVD drive it would probably not be possible to downgrade a HDMI box to vulnerable kernel.

I also believe that the only hope is to dump the NAND flash in the DVD drive and see if the unique drive key is in there. It is easy to spot in a hex dump. Personally I would use an Infectus to dump the drive's NAND rather than to desolder it and use an external programmer, but both ways would work. I have also used a Globe v2 chip (same vendor as Infectus) to dump and repair a Hitachi drive that was bricked. Software flashing tools only patch the flash, so I believe there is a chance that the drive key is intact, if that block wasn't patched.

Just my 10 cents..

 

Yes, it gets 5V from the drive as long as the 360 is powered on.

It costs more than a simple modchip, but I find it reasonable compared to most others NAND programmers.

I did find the Hitachi installation a little bit complicated, since I had some problems with the "quicksolder". I would use thin AWG32 kynar wire myself, and have some flex and a desoldering braid ready, in case you get solder between the NANDs legs.

 

I have a chip to recover some "dead" hitachi drives. It works giving the drive other way to be detected by the computer, then you can read the firm. It is installed like a 79passkey. I have installed lots of 79passkey, if you want you can send me just the board of the drive, and ill try to take the firmware. Using willem is more difficult, have you seen the epoxy that covers the chip? is very difficult to clean at it all, but not impossible.

 

Did you ever get this fixed? if not i may be able to help you out ,my launch console (Xenon board for you tech guys) has had many fits and tantrums over the years.... 4 cases of Rrod all different causes, dvd drive spasm's (auto eject during gameplay) and many other aches and pains that i have managed to pin down and fix.

So if anyone can help its me :thumbsup: hit me up with a pm

 

my experience

Hi, its very difficult to recover a bricked hitachi drive. I have some facts of your problem

1 All 79 boards have epoxy, then, yours is not 79 or epoxy have been removed.
2 there is a chip, i thought "chilli" or something like that , it give to some bricked drives the posibility of be recognized by the pc.
3 79 pass key will not work.

I bought a willem, but i never have used it, if you send me the board and the instructions to recover the data with the willem ill do for you, i want to learn!!

Please if u need some help please pm
