NEED JASPER 256MB Nand's

[coolshrimp]

Hey iv got a console here that used to be a jtag.
Owner accidenty updated it with MS update and unjtaged it.

he figured he could just reflash it with freeboot image
and this caused it to give 0022
i am now asked to fix it

problem is now i only have:
Jasper 256MB Console - 0022
And 9199 FreeBOOT Dump

i have no original dump and no way to get CPU Key as its no longer a jtag.
so only thing i can do now is flash an original nand and inject KV from 9199 image.

What i need is Original Nand dumps from dash 9199 - 12625

i cannot use clean nands since console was updated to newer dash any older dash will not load as it would be like downgrading witch you cannot do..

all i need is original dumps fo a Jasper 256MB
Dashes 9199, 12611, 12625
can be from any non jtaged console.

please post me links for download megaupload prefered.

So someone JTAG'd and didn't protect their efuse? Oops!

Getting the original NAND dump is one part of the puzzle - you'll need to know the LDVs for it too.

Does he not have ANYTHING left of the original NAND or was it a DIY job and nothing was saved?

 

[coolshrimp]

DIY all i have to work with is a FreeBOOT 9199 dump

and he's def overwritten the CB to the non-exploitable?

im pritty sure iv tried xell, xellous, the 9199 dump, and creating an original from the 9199 image and nothing i get random(0022, and random lights some times.) also did a reball to be sure. if i remove video cable i dont get 4 red lights i get like 2 red lights on oppisite corners somtimes 4 solid green lights

also tried diff smc wiring and files still no go.

 

[Martin C]

surely if you dumped then NAND before trying others then 360Flash Tool should tell you what the new CB version is?

 

[coolshrimp]

well they tried to flash the freeboot back to it so i could not dump the updated nand.
the CB from 9199 FB is jtagable but thats not what we need.

 

[Martin C]

If it's no longer a JTAG and he doesn't have the original dump (OR a copy of the CPU key), he's screwed. Injecting a KV is only one part of the puzzle. There are a load more files which are encrypted by the CPU key.

You would need the CPU key whatever you needed to do with it.

 

[coolshrimp]

yea thats what i was figuring well for parts now

What a bloody shame

It takes two minutes to protect the CB efuse nad people are still too lazy to do it!!
