Unbanning Xbox 360 From Live - The Facts
Posted by XanTium | November 13 21:14 EST | News Category: Xbox360

I see lots of sites posting today about a way to unban Xbox 360 from LIVE often linking to a thread made on our forums here.

This method has been known for a long time (since the King Kong Exploit days) and does indeed 'work'. Basically you swap the Keyvault (or 'KV' in short, it stores stuff like console certificates, per-box private keys, DVD key, etc) inside the NAND with the KV from an unbanned console. While technically very different you could somewhat compare it to swapping eeprom data during the Xbox1 days.

However there's a (really) big 'IF' (besides the required tech knowledge) ... you need the (unique) CPU key of your banned console - without it you can't correctly write (or encrypt if you want) the new KV data in the NAND bin of your banned console.
Now you wonder how to get the CPU-key ... well by running XeLL of course!
To run XeLL u need to perform the JTAG hack (or the King Kong exploit, but that's even more outdated) ... and if you got banned the last few weeks it means you updated to the latest dashboard/kernel (else you can't get on LIVE).
And that's the problem... Microsoft patched the JTAG hack since kernel 849x (July 2009) ... so no way to boot up XeLL (= no realistic way for you to get the CPU-key atm) and thus no way to swap the KV data in your NAND image.
And then there's also added KV protection (hashing) on newer motherboards (Falcon+ ? and kernel 1888 won't boot on those), but if you can't even get your CPU-key it doesn't matter much to do deeper into this problem.
The only way it would work is if you retrieved the CPU-key of your old banned 360 before you updated to anything over 849x. If you did that you probably know about all of this and I'm not telling you anything new

Downgrading kernel is not an option either, older kernels won't boot as both kernel and CB fuses were burned during the various updates MS performed, and you can't bypass that without ... your CPU-key.

Hope that explains the situation a bit (tried to make it not 'too' technical)
On a side-note, it would probably be pretty easy for MS to detect KV-swaps (like HW-mismatches etc).
Side-note2: in case it wasn't obvious yet those "unban isos" are fake and iXtreme LT won't unban you (it will instead try to avoid new bans).

So basically "If you got banned This wave you can't unban yourself, sorry".

thank god for you not making it too technical.

I think you scared off like %85 percent of people. j/k.

Oh and to do this you need to have a non 256 or non 512mb jasper that got banned. Cause those two versions of the 360 don't have the Xell image for it yet.

And one other thing. people would be willing to give someone their kv from an unbanned console? Wont' that show up as two xboxes with same info connected to live?

And this is very technical for the average person to do. I will be doing it however.

HUGE scam on various sites to give you a magic .ISO that unbans your xbox.
****THIS IS A SCAM PEOPLE THERE IS NO MAGIC DISC TO UNBAN YOUR XBOX 360****

Just waiting on ixtreme LT or something similar.

warbeast · « **Reply #6 on:** November 13, 2009, 07:41:00 PM »

you should also swap the config.bin that holds the mac address so it it matchers with the keyvault ur using

also if you dont have a spare keyvault can u edit a fake invaild one just to help prevent ms removing the hdd installs i know it wont help to unban but will still be usefull

Muzzakus · « **Reply #7 on:** November 13, 2009, 07:46:00 PM »

I know this may be crazy, but is there a pattern to the CPU keys? Is a keygen a possibility?

Wouldnt that be a shot in the balls for M$, haha.

no but if they banned 1 million then thats 1 million people that may now be looking into finding new exploits

Welcome to 2006! It's amazing how this "news" peaks it's misinformed head out of nowhere, only to stir up false hopes for those who are banned.

Hopefully there will be a new hack found that will not be thwarted by M$... At least anytime soon!

Actually, they've been up on xbins a few days, now.

I have got lots of boards here that have RROD.
Another method of unbanning not described here would be to swap both the TSOP and the CPU from another xbox.

Of course you need to have some nice rework and reballing skills but i am sure there are a few people on x-scene that can handle it.

That should indeed work (noone confirmed doing it tho afaik) ... but like u said, u have to swap BOTH the NAND (or TSOP) and CPU chip (for matching 1bl data) ... doesn't sound like an easy job

With the amount of RRoD consoles out there it would be a nice 'test' for people with the right tools tho.

KV hashing

wow seems Microsoft used Xenon as a Guinea Pig.

Thank you for pointing this out, I've been trying to make people understand that all day!

So close! All 1BL keys are the same, swapping the CPU would match the swapped NANDs CPU key, not 1BL key.

You were on the right track though.
