To change the keyvault to a differnt kv like a already banned keyvault you would still have to get the original nand backup and cpu key.  Then you open in 360 flash tool and inject the banned KV and fix the dvd key to match the drive, doesn't even have to be the same model motherboard.   I made a guide on how to do so.  I tested it out and it is good to go.  By doing this you would be prepared when other things develop and you don't need to mess with your original nand.

This is fine, but what I'm talking about is the fact that none of the dual-nand set-ups support the big-block jaspers. For it to work you have to turn your console into a 16mb nand unit and the XD-card tutorial details this.

I was curious about this as well.  I know you can change things around so it is like a 16mb unit but can you convert the large dump to be 16mb and it still be like the original and safe for live?  If so I dont see why you couldnt desolder the 256 or 512 TSOP after getting a dump of it then solder a 16mb chip in its place and putting your converted 16mb image on it then you could do the dual setup.

Yes, but where's the fun in that

no fun but when you can pick up a rrod in some places for a fiver it works out a hell of a lot cheaper

I'm prolly wrong, but don't the BB jaspers only use the first 16mb for the nand image and the rest for storage?

I've never gotten my hand on one to try it out.  You might be able to play with it and see.  I have a bunch of boards with 16mb TSOPs laying around and that might help people if you figure that out.  There really is no point in having a big block nand nowadays anyway.  2 saves and its full.  lol

**EDIT** You could try dumping it like you would a 16mb tsop and then read it with flash360 and see if it looks good.

wouldnt it be easier just to use the 512 for live rather than desoldering the whole chip. then use a 16mb for the glitch? that way you are not messing with anything the system uses when in standard mode?

It would be nice but the problem is that the xbox360 motherboard has a different configuration for the 16mb nand and the 512/256 nands as shown in the pic below.  You have to change the resistors to make the 16mb nand work (in this case the cygnos360v2) and that would make the onboard 512/256 not work anymore.  


This is a pic from the XD Card mod guide written by "mastag21"

And this is a quote from the XD Card mod guide from "mastag21"

"You are basically switching 2 resistors and this makes the XBOX 360 think it is a SMALL-BLOCK system.
This does render the onboard NAND non-bootable. You may still be able to read/write to it but the
system will not allow it to boot because of the switching of resistors for SMALL-BLOCK."

Also I dont think it wouldn't be Live safe to go from Big Block to small block nand as long as the nand files are all there and look original to the console.

I was under the impression that changing the resistors crippled the onboard nand down to 16mb, not disable it altogether. I wish I could find that xd card tut again.

edit: nevermind, you answered my question.

edit2: wonder if changing the resistors and swapping the TSOP would work?

I seriously think it would work.  without a doubt!  got me wishing I had one just to try it out.  lol

the xd mod is identical to the 'nandwhich'.. as well as the cygnos dual boot. they are all basically the same chips in a different package.

you COULD do a dual boot with 512mb jasper and XD/cygnos but it would require switching those resistors as well. your best bet is to nandwhich a second 512 or replace the 16mb on the cygnos with a 512...

if your intentions are to dual boot and be live safe i dont think its possible to switch a 512mb nand with a 16mb nand as the 512mb nand uses a 64mb kernel.

also,

<<<<<<<<<<<-------------!!!!!!!!!!!!!!!!!------------ iLLNESS, does not take credit for these discoveries there is already a large thread from the xbr/freeboot days where others have done this work. he is just resurrecting the info due to the response from other users.

dual nand 360 slim aka 'nandwhich'

not the clearest picture.. didnt have time for a video nor do i want to show how ghetto the switch is at the time being but its just a manual resolder to switch nands right now.

you can see top nand is wired to 3.3v through 10k pullup and to CE (not shown, underside). CE 10k resistor was removed from southbridge line.

i need to pickup a switch tomorrow to do the switching until i do some pic coding or begging to switch to xell on eject

The quick-solder points are the same as the V2, you just have to determine which pad corresponds to the quick-solder points.

news to me... and great news too, been waiting years for these videos to bring me back to the scene.  


as far as live goes, in the XBOX1, if you got banned, it was almost always the console that got banned, correct?

meaning you could always "unhack" an XBOX after flashing a new EEPROM, and Live would work again, and again, and again...

This looks to be true for 360 too, maybe?


Personally I dont give a ____!  I have a Slim for Live, and 3 RROD 360's waiting to be opened and played with.  

 Just waiting for the right moment to pounce.

 I was good @ modding the shit outve xbox1 (all through what I learned here), and it wont be long till its easy enough for a n00b like me to start modding my 360's.

 Keep up the good work people!
I cant wait!

 Ive lost/replaced so many damn 360 discs from the kids bouncing around or just someone bumping the 360,I cant wait to be able to back em up to the HDD and NEVER have to worry bout that again.
