[edit XanTium: more info about this hack: http://forums.xbox-scene.com/index.php?showtopic=696317 ]

what you need:

your 8955 live console + cpu key
a 2nd unbanned console
nandpro b + flash cable
xell loader
degraded
1888 fs
robinsod's flashtool

process:

use nandpro and dump nand from unbanned console.
flash xell and use jtag hack to obtain cpu key.
use flashtool to extract file system.

dump nand from 8955 console.
use flashtool to patch nand dump with kv.bin from unbanned console.
save patched file (patched_kv.bin).

open degraded + 1888 fs.
create 1888 downgrader image (downgrader.bin) from your patched_kv.bin file.

flash downgrader.bin to 8955 console.
attach hdd + ethernet cable and boot console.

connect to live and update to 8955 dashboard.

console is now fully working and unbanned!

in doing this, wouldnt you not be able to play both consoles online simultaneously?

Good tut, only helpful if you got your CPU key pre-summer 09 update.

gonna give it a shot,
reply back later to confirm

Omg this is amazing, what does 8955 Console mean? And also can you post a site where you can buy all the necessary tools for unbanning a console

All the tools are free,
a 8955 console means you have played on live and have the update.

The only way to get the cpukey is to have run xell.
Only way to run xell is if you dash version is below 8XXXX you can find this in the system info of the xbox.
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 aswell.

Unless you backedup your cpukey from in the past.

ive been storing my cpukey since aug 2007. today i actually used it for something.

You think there will be a way to run Xell if the dash version is above 8XXXX in the future?
Also this question wasn't answered

in doing this, wouldnt you not be able to play both consoles online simultaneously?

No one knows, probably not



Yes, for 30 seconds or less, then you will be banned again. (I think)

So if u have your unbanned cpukey (from xbox: a) from before summer 09 update, then shouldn't (after u get banned on xbox: a) b able to reflash the xbox with the old cpukey? Or does it automatically reban u as soon as u log back into XBL?

contents of the keyvault are banned. not the cpu key. that is why you patch orig.bin from 8955 console with kv from unbanned console.

I don't get it completely.
For what do you need the cpu-key of the banned console?

k0mpresd: but who has the updated console and doesnt has the cpukey, isn't possible, because to use the jtag hack(need to catch the cpukey) your dashboard need to be in a version earlier of the 849x.. Do you know how to resolve it?
Thanks and sorry for my English.

mainly, to decrypt nand dump so it is possible to patch new kv.



there is no solution for updated consoles if you do not already have cpu key.

thanks, but you know a solution to catch the cpukey?

Sorry for my ignorance but I have a banned console, and i also have a console that has the old software on but that has an E73 error - would i still be able to link this up and retrieve the information i need from it so that i can use that on the banned one or would the pc not recognise it due to the error?

Heres a tricky question. Lets say you have a banned 360 and a whole pile of RROD boards kicking around, can the following be done. (lets assume the RROD boards have been sitting around for at least 2 years obviously with no updates).

If i was to either read the nand off a rrod board or remove the nand and cpu is it possible to do the following to get the box unbanned... (i am not worried about resoldering them, thats no big deal for me)

option 1. get a read from the Nand of the RROD board, overwrite that bin file to the Nand of the banned 360 and then replace the CPU of the banned box with the RROD CPU, do the jtag hack to get the cpukey, DVD key and then put original fw back onto the correct dvd etc..

Or...


option 2. remove nand from RROD board and resolder to banned 360 and then replace the CPU from banned box with the RROD CPU, do the jtag hack to get the cpukey, DVD key and thenput original fw back onto the correct dvd etc..

Any thoughts, it seems to me this should satisfy the checks in order to get it back online again ? (assuming of course the RROD console wasn't banned to start with, that would be my luck LOL:)

to patch kv.bin, do we have to get 1BL? How to get 1BL?
Thank you in advance

google is your best friend

both would work. the point is to get a matching nand/cpukey + unbanned keyvault. however you can accomplish that will get you back online.

Thanks for the reply, i gonna give option 1 a shot and see what happens

Interested to see how this goes - keep us posted pal, and good luck! lol

nooob question does 8955 refer to the motherboard if so how do i find out number my one is

yeah i hope that works, cause I've got 6 rrod boards just laying here beside me

8955 refers to current dashboard version. i did this on a xenon board never sent back for rrod repair that still had 1888 base kernel.

8955 just checked mine its 8955 so would i need a unbanned 360 to do this hack ?

yes. plus the cpukey for your banned console. and theres currently no way to obtain cpukey on 8xxx+ console.

K, heres my status. I read the Nand perfectly on the RROD 360. I have removed the CPU (from RROD box), and for the hell of it i attempted to read the Nand again after i cleaned up all the solder blobs left on the motherboard... I was able to read the Nand again, and got an identical comparison to the read i done initially. Next step now is to remove the GPU from the banned 360, do the swap, reprogram the Nand and see what happens, but that is for tomorrow.
At least the Nand doesnt have to be desoldered from the RROD board so that is a plus

edit... i did practice on the RROD board with my Solder Balls and CPU mask overlay and it took a couple of attempts but i was able to get the solder balls on all the pads. I know it should be on the CPU itself but the pads on the mobo look more solid.

This does work!!!

I tested it today just to see if it would. Not really that difficult either....thanks for the heads up.

I don't play burnt games online because any game good enough to play online is worth buying to me, but it is still useful information. Stuff like this can only lead to more and more advances in the future.

I personally bought a banned console for like $30 a few years back and just play burnt games on it from time to time to see if I like them. If I do I tend to buy them for my non-modded console.

This really is pretty easy....the problem is for some reason opening a gaming console intimidates people. They don't think of it as just a PC so it scares them. And soldering!....oh no. LOL.

Everyone is all worried about the recent bannings and think that Microsoft has finally fixed the problem permanently. I don't see that at all, in fact, I see the opposite. I say within the year the xbox 360 is fully hacked and you have xbmc360 with endless rom's and still have the ability to play burnt games online relatively worry free. Maybe I'm optimistic, but this about a 360 that actually has good media center capabilites, free games, endless rom's (including xbox 1 rom's), plus natal and all that jazz. Sounds cool to me.

The main deterrent is the relentless updates, but as I understand it there is only a limited about of update fuses the xbox 360 has....so what happens when they are all used? I am sure Microsoft will still be able to update, but the nand will remain the same after that in all future updates. Then we have something concrete and permanent to work with hopefully.

If your dash is 8XXXX or up theres no way to get the cpukey.
Just wait and maybe they will find a new exploit.

it seems that if you got a ban with the past few weeks ( today being nov. 12 2009 ), this will not work, correct?

if you know the dvd key of the rrod 360 then you dont care about getting the cpu key (although that would be a nice bonus). Once you transfer the new cpu and nand bin file all you need to do is put in the original dvd with original bin file that belonged to the RROD 360 (or same model dvd rom with orig bin file)

I would really like to find a zif socket or equivalent socket for the cpu so i could put it on one of my Free 60 machines.

Sorry if I sound noobish, but with this can I play on live again and not be banned?

i have a question.

banned console A
not banned console B

unbanned console A using KV of console B.
then if console A will be got re-ban, this meaning console B get ban too? because of using same KV both of these.

Back to the dual online scenario.

So Both box A and B can/cannot be online at the same time?

The 30sec comment means that someone has to be logged in with a difference greater then 30 seconds?

Or you have under 30 seconds to wtf get off?

is there a tutorial for this anywhere?

i just bought a used xbox 360 manufactured date was 07, and it was sold sept. of this year.

could i use this trick to unban my brothers xbox so he could play online again? i dont need to play mine online?

ok so this is basically pointless because everyone is updated so how is this of any use to us

Well if you read some of the posts, you would realize that RRoD 360s may be used and there are a lot of situations were this is applicable.

Pretty sure the OP wasn't posting a fix all / end all solution.
Just rather sharing with us something they figured out.

Thanks kindly OP.

greatest news this week, the scene is moving quickly....

M$ smirk must be a frown right now.....LOL

sure. i spent the better part of a day trying to figure out the easiest/most effective way to accomplish my task at hand (getting my console back online). and this process is what i came up with. and like i said previously, i had been storing my cpukey since aug 07. this isnt a fix all/end all. this assumes you have some background knowledge.

What happened to Christmas lights when patching KV post-NXE?

http://www.xboxhacker.net/index.php?topic=7872.120

EDIT: Have you done any testing on Falcon/Opus/Jasper boards? You did say that you had been holding on to your key since 2007, which leads me to believe you are using a Xenon, and this method won't work for all consoles.

OK. I've got an interesting situation here. Hear me out and tell me if this will work. I've got two Xbox 360's with THE SAME SERIAL number. Both are the same revision Falcon motherboard and they both have the same serial number in the dashboard. One is pre-summer 09 dashboard (7xxx, and obviously unbanned), the other is 8955 and banned. I don't have the CPU key of either console.

My question is, can I use the CPU key from the 7xxx Xbox 360 to unban my 8955 banned console or is the CPU key unique to each Xbox 360, regardless of serial number?

CPU Key is unique.

Thanks for the quick, straightforward reply.

Hey guys so is there a way to use this to get the cpu key to rewrite a drive key that doesnt match with the xbox? So you can replace a 360 drive if the drive you have has the wrong dvd key? Help me if you can as I have some systems with mismatched drives. Thanks.

Yes, on any motherboard that you can properly edit the keyvault on post-NXE (Read: none past Falcon without heavy modification [Source]), you can patch the region/OSIG to your hearts content. However it might be easier to simply read the OSIG in 360 Flash Tool, and spoof your mismatched drives accordingly.

EXCELLENT NEWS!!! Thanks! you just made my week... I have so many 360's that I can get up and going now... now to learn how to do it!

Xoxide! Check your PM. Thanks!

Or you can save the headache, buy another xbox from walmart, do a switcharooni, then return the defective back. problem solved.

No, I want to learn how to do this anyway as I have many good 360's here that work great but have mismatched drives.
