Jasper 512MB JTAG help

[Sephious]

Anyone have any ideas??? I have been doing some searching and it sounds like I need to get linux running on it.... But not enough info. Hordak got it working somehow "I extracted the kv, secdata etc from the 512 dump with bincrypt build28. When I open it in kvmodder it has all the info there like serial and drive key, region, but says its not moddable. What is the extended keyvault? If I open that in kvmodder it says it is moddable but all the other info is either blank or zeroes. Region is correct.". What did you do? where are the keys hidden at in the binary? This has been driving me nutz for days, none of the flash tools work because of the big block dump..... Someone says change the copyright data in the nand dump but what year do I change it to?

1. Read your Nand twice
2. Compare your files with Winhex and check for differences
3. Download the pre made hack for your 360 ( mine is a Jasper )
4. nandpro lpt: -w256/-w512 jasper_6723_hack_for_256mb_512mb.bin 0
5. Boot up 360 which will now display the CPU key
6. Download 360 Flash Tool version 0.6
7. Make a copy of your Nand flash that was read in step 1
8. Open Nand with Winhex and change the copyright TO date to 2005
9. Enter your CPU key into Cxkey.txt from 360FlashTool folder
00000000000000000000000000000000,Enteryourcpukeyhere

10. Run 360 Flash Tool
11. If the manufacture dates display correctly, you have followed this correctly.

Great I got it, changed the file extension to .raw to open the file in flashtool 0.6. Thank you Johnny

"you didn't insert your keyvault, that's why". How do I get the keyvault>? Sorry for asking dumb questions my nand is 512 by the way

Check the readme that came with nandpro

why not split into smaller chunks? the smaller the chunk, the faster you can re-read them if they are bad.
use 0 200
200 400
400 600
600 800

200block chunks arent too bad to re-read.. 64mb chunk still takes a few hours over lpt.

you can make a batch script to accomplish this so you dont need to be at the pc. ive posted a generic batch script somewhere on these forums to automate jasper read/write as far as multiple dumps is concerned, just not chunks.

That's not correct...At least, I do not believe so,

it should be:

0 200
200 200
400 200
600 200
800 200


correct me if I am wrong.

Ok, sorry about reviving this thread, but I got a very similar problem and could not find the solution just by searching.

Got a 512mb jasper, two indentical dumps, flashed the jasper hack in, it did show up my cpu key but gave the "kv_get_dvd_key failure: kv_read..."

I was able to open my dump changing it to raw and following the steps that Johnnyb posted, looks like all the info is there, but how do I "insert the kv" to allow the hack to move on?

Edit: Ok, got the kv.bin with BinCrypt (great tool btw), now how to inject it?

Another question, got one 360 that I gotta retrieve the dvd key, after I did the whole thing and got the key, is just flash the original nand back? Also, since it is a 512mb nand, will it take another 12-16 hours to flash it back or can I flash just the first 50 blocks that where changed with the jasper hack?

[johnnyb]

This is how you extract KV and Config from your 512mb dump

nandpro orig.bin: -r512 rawkv.bin 1 1
nandpro orig.bin: -r512 rawconfig.bin ef7 2

Inject KV and config into the XBR Hack

nandpro XBR_Jasper_6723_256_512_8955_1_fixed.bin: -w512 rawkv.bin 1 1
nandpro XBR_Jasper_6723_256_512_8955_1_fixed.bin: -w512 rawconfig.bin ef7 2

You then write the modfied XBR flash to your nand. ( This will only write 60mb, as thats the file size )

nandpro lpt: -w512 XBR_Jasper_6723_256_512_8955_1_fixed.bin

Thanks, about writing back the original nand, only the first 50 blocks where needed looks like, got one working perfect here. Thanks!

[morenomdz]

Another question poped here, since I have another 4 512mb jaspers to retrieve the dvdkey, do I have to read the whole f***ing 512mb nand or can I read just the first 50 blocks, or even just the first 16mbs, write the hack in, get the dvd key, write the first blocks back and then I am good?

Unless I am missing something, I don't get the point of having the whole image if we only change the very first blocks.

O.o

Sorry if it was dumb lawl!

trying to flash xell to it now, and i get an error.

I did nandpro usb: -w512 jasper_6723_hack_for_256mb_512mb.bin 0

and it says "Couldn't open jasper_6723_hack_for_256mb_512mb.bin for read"


edit: nm, user error  

I've booted xell now, and after it displays the cpu key it says
kv_get_dvd_key Failure: kv_read
this hash check failed probably as a result of decryption failure... etc

Is it supposed to say that? gentoo etc boots ok

How did you fix the error "Couldn't open jasper_6723_hack_for_256mb_512mb.bin for read".
what was the exact command ? If anyone knows. Im also getting nandpro XBR_Jasper_6723_256_512_8955_1_fixed.bin is not a recognized as an internal or external command. Help 

[hroark]

Im also getting nandpro XBR_Jasper_6723_256_512_8955_1_fixed.bin is not a recognized as an internal or external command. Help  

Hi senas8

can you explain exactly what you have done up until now, did you read your nand yet?, did you make sure it was a good back up?

"recognized as an internal or external command" is a DOS error meaning you are either spelling your command wrong or the file your are trying to execute "nandpro.exe" is not in your current directory or in your path

[senas8]

Hi thanks for replying. Yes I dumped the nand double dumped it. All is good. dumped the rawkv.bin 1 1 and rawconfig.bin. Im trying to inject those into xbr.bin And thats where im getting the errors. Im trying to cd into the nandpro20b directory ... I guess im not doing it right.

Also one tutorial said to flash xell after dumping the nand 2 times checking if the dumps are identical with commander. Another tutorial says to dump the rawkvbinand rawcofig and inject it into XBR_Jasper_6723_256_512_8955_1_fixed. And then flashing the nand.
This is the command im using: C:\Nandpro20b\nandpro.exe nandpro XBR.bin: -w512 rawkv.bin
doing that command gives me:
usage:
nandpro dev: -r#
nandpro dev: -w#
etc
Never mind got it working..

So what's the problem with lflash writing to 256mb/512mb NANDs? Writing to 16mb works, right?

[VoDa]

Hello guys...
i have one "little" question...
How long take a reading 256 and 512mb NAND thru LPT?
Because if i reading a 16mb NAND around 15-20min and if i counting time
my results is for 256 (15min x 16 = 4hours) and 512 ( 15min x 32 = 8hours)? 
Is it right or this time is much shorter? Because i cant imagine if i read 512 twice or
threetimes ... It take 24hours!!! f***

You don't have to read whole nand, just first 1000 blocks. Rest of nand it's just memory card.

finally some newbie who speaks sense... kind of

actually all you need is a good kv, config, and first 2 MB, then you can use XeLLous to perform a dump through httpd

[mataman]

Yes it can be done that way also
