Overview/Reality of the Method:

This method is not new, has been known and trusted since a long time. Basically, what we do is swap the KeyVault (or ‘KV’ in short. KV stores data like console certificates, per-box private keys, DVD keys, etc.) inside the NAND with the KV from an unbanned console. (While this is technically very different, you could somewhat compare it to swapping EEPROM data during the Xbox1 days.)

However there’s a Big ‘IF‘ in this method. 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.

How to get the CPU-key? Run XeLL it will give you that info. To run XeLL, you need to perform the JTAG hack (or the King Kong exploit, but that’s even more outdated) and if you got banned the last few weeks it means you updated to the latest dashboard/kernel (else you can’t get on LIVE).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 (i.e. no realistic way for you to get the CPU-key atm) and thus no way to swap the KV data in your NAND image.
To add to the mess, 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 nothing written here is 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. Or if you played on live in the last 3 months your out of luck. Also all the new wave 4 games have the update that will disable xell from working so your out of luck there as well.

Hope that explains the situation a bit, if all looks well, you can proceed with the method. (it’s not easy)

Before you Begin:
Make sure you have the following stuff handy with you:

1.Your Xbox 360 (8955) live console & CPU key
2.A 2nd Unbanned console
3.NANDPro b + Flash cable
4.Xell loader
5.degraded
6.1888 fs
7.Robinsod’s flashtool
Method:

Step 1. Use NANDPro and dump NAND from unbanned console. (Download)
Step 2. Flash Xell and use JTAG hack to obtain cpu key.
Step 3. Use flashtool to extract file system.

Step 4. Dump NAND from 8955 console.
Step 5. Use flashtool to patch nand dump with kv.bin from unbanned console.
Step 6. Save patched file (patched_kv.bin).

Step 7. Open degraded + 1888 fs.
Step 8. Create 1888 downgrader image (downgrader.bin) from your patched_kv.bin file.

Step 9. Flash downgrader.bin to 8955 console.
Step 10. Attach HDD + ethernet cable and boot console. Connect to live and update to 8955 dashboard.

Your console is now fully working and un-banned from LIVE. You will have to follow this procedure everytime you get banned.

hv any1 tried this??? leave a comment.....

I have a better idea, get an untempered console.

I agreed, getting unban console causing much hassle. it's not like you're being saved from ban thereafter.

This method exist for a long long time already and the primary onjective is to simply take away to ban flag.

but latest update provided the Install game feature to banned console. So tell me what's the good of this mod?

in before close! woot!

ill rather buy a new unit than going thru all those steps above >.>

ok move along ,nothing to see here

there's a big flaw with this method. you need key from unbanned console. if you got 1 unbanned console already, why waste time unbanned the banned console?

and when both console log in to LIVE!, what would MS do with 2 console with same keys??

mr faud, share with us your success story. lets fill this thread with sucess stories. show all the unmodded console owners what losers they are

Post of the day.

hahahahaha


amusing

technical thread ppl. if you just want to enjoy games, live etc, move along. nothing to see here. there are people who loves to tear down every gadget they have for the sake of fun. hence the thread "Overclockers united" etc.

interesting method. however i think most ppl aready updated their fw directly via live or via games they played.

just interested to know can we run unsigned xex without jtag?

Owh I see what you mean here but TS really need to remove the last sentence of his post or else this thread will attract more and more unwanted attention.

and usually people around here while liked to explore some useful mods such as the one posted by TS, mod for unban & to run pirate game is seriously not welcomed....at least on this subtopic as this is not "Overclockers United" sorta thread.
