What chip on the 360 contains the DVD key? Is it possible to desolder the flash or eprom off a dead 360 and solder it to a working 360 with unknown key? I have 2 dead boards with keys and two good boards with no keys!!

TSOP means Thin Small Outline Package, that's not much help as an answer.

@ relaxxx - You can't just swap a chip from the 360 motherboard to another one and be done, you'd have to swap the NAND (U2E1) and the CPU to make that happen.

For now those boards with unknown keys are pretty much useless.

Am I worng about DVD key was store in TSOP? Please guide me where we can find missing DVD key on 360 except from DVD drive PCB it self.

I had read in forum somebody was tried to switch TSOP from one system to another, but it was not working.
Is there any way to recover the DVD key other then drive PCB? (IMG:style_emoticons/default/uhh.gif)

The question is about the motherboard, not just the key. The key is stored on the NAND chip, it has to be so the one on the drive has something to match up with, but without the key from the CPU that NAND chip is useless, so ya have to swap both from one motherboard to another for that to work.

The issue most go thru is needing to swap the DVD drive, where the key can be obtained from the original drive and a new drive installed. But to swap motherboard keys, like is being asked here, can't be done as of right now unless the 360 is complete and working, in which case there's no point, so it's a catch-22. If ya need more details on all the technical info on it hit up the forums on xboxhacker.net, lot more info on it there.

Thanks a lot RDC.

So I have to think about switching both NAND and CPU from known key dead MOB to unknown key working MOB. (IMG:style_emoticons/default/ohmy.gif)
Before, I thought I don't need to switch both. But I haven't try yet.
Uhmmm, reballing CPU is time consuming. I had try to reball with air flow rework station was give me headache.

I was looking for IR rework station. I'm not sure it worth it or not.
I'm look into it. (IMG:style_emoticons/default/rolleyes.gif)

I thought NAND was a logic gate? It doesn't make any sense that the CPU would need to be swapped, That would be way more work for Microsoft than necessary, CPU's dies are reproduced from masters like CD ROMS and should be identical. The original xbox HD key was on a small 8 pin eprom. The TSOP flash or another eprom chip (if there is any) seems far more likely. MS would be retarded to have uniquely flashed CPU's! Surely someone here must have swapped the TSOP flash chip and found the answer.

NAND is a type of flash architecture as well and the NAND chip has been swapped on it's own before, that will not work as the CPU key is unique to each CPU, it's not an Intel or AMD chip that ya can just swap around between consoles like ya can on a PC. Feel free to swap the NAND chip if ya don't believe what you've read here, but please post your results afterwards, or ya can search around on the net, specifically the xboxhacker.net forums, for more info on it and save the waste of time it all would be, which would have been a good place to start, looking some of this info up as it's been known for quite awhile now, and it still hasn't been hacked yet. M$ didn't mess around on that aspect of it, the DVD drive they left open to being hacked and swappng drives has become quite easy to do, but the motherboard is a completely different story.

I can't get the search function to even work at xboxhacker.net!

There's nothing wrong with Google, or sifting thru a few pages if you're really interested in looking up the info, but it's just going to confirm what you've already read here.

Since MS made the thing, they have the facilities to be able to change the DVD key on the motherboard since people have reported the same motherboards coming back from repairs but different DVD keys.

yee..i'm pretty sure the key is stored in NAND and CPU stored the decryption key...
