Free60 JTAG/SMC XeLL Hack for Jasper-256/512mb Motherboards
Posted by XanTium | November 15 19:35 EST | News Category: Xbox360
 
This was actually released last week already, but with all the BAN news we kinda missed it (but we're still the first site to report about it ;)) ... so here it is :)
After the release of the hack for Xenon, Falcon/Opus, Zephyr and Jasper-16mb motherboards, here's the Free60 JTAG/SMC XeLL Hack for Jasper (v4) motherboards with 256 and 512mb NAND chips.
This NAND image will boot your Xbox360 right into XeLL, which allows you to launch linux distros or run libxenon homebrew software, as long as you never upgraded it via the normal MS upgrade procedures to kernel 849x or higher.

From the readme/nfo:


Finally the Jasper JTAG Hack is here :)
This is XELL (Redline99's XeLL) inserted into 6723 Jasper-Kernel.

Don't wonder about the Filesize, its correct like that. It just flashes the beginning of the NAND so your console specific data like MAC adress will stay.

Of course you should have a working backup of your NAND before you proceed.

*** NOTE ***
It's for the Large Block Jaspers, 256MB and 512MB ;)


Someone also sent us this nice diagram made by Sandungas about how to wire the JTAG hack and SPI (for NAND reading/writing via LTP with nandpro) on Falcon/Zephyr/Jasper motherboards.
*Update* Latest version of the diagram made by Sandungas on the free60 wiki.

holy crap, does this mean we can read the nand on the Jaspers?

this is great news....
now is there any way to write code to the nand, not just reflash?

do we still need a second nand to get unbanned?

either way, great news.

As usual it looks like you guys are READING what you WANT TO SEE and missing out the important part

which is


This NAND image will boot your Xbox360 right into XeLL, which allows you to launch linux distros or run libxenon homebrew software, as long as you never upgraded it via the normal MS upgrade procedures to kernel 849x or higher.


Now think if you got banned you have the latest dash so no you cannot use this to get unbanned

.........


YET!

What if you have the cygnos v2.0?

Could you play offline/Linux with one Nand & online/latest kernal with other Nand?
I doubt it otherwise it would be mentioned more...

Maybe one day smile.gif

no. (1bl update disables the smc hack)

this was on xbins about a week ago.

Edit:

This is only possible on consoles that haven't been on live since 8-10-09, where manufactured before 6-19-09 and have pre 849x dash.

This hack isn't working on new motherboards, where base CB is locked to 6750!

Does this mean , assuming we havent upgraded the kernel, we will be able to retrieve the dvd key, even if it has an unmoddable liteon?

Hi,

I have a brand new Arcade Jasper (manufacture date 2009-08-08) with dashboard version 2.0.7363. The internal memory is 322MB(512?). Do I have anything to worry about? Is my arcade hackable with this JTAG hack? Is my motherboard compatible? Thanks for your help smile.gif

The SPI is fully compatible with all motherboard models (same solder points in all motherborads)
The JTAG hack is "blocked" in new manufactured motherboards (blocked at the bootloader level)

To be sure what bootloader do you have... you can make a dump of your nand with SPI... and later, open this dump in "360 flash tool"
360 flash tool can show you info of the dump contents (Cx sections) even without your CPU-key
360 flash tool actually cant open jasper nand dumps, but if im not wrong... a new version is in development

If your bootloader works with the JTAG hack... then you can write the hacked_jasper_nand_image.bin (or whatever) in your nand to retrieve your CPU-key (and other efuse security data)

May I ask:

If I only wanted to back up/write to my NAND chip data, would I only need to wire up the SPI part? And to clarify, if I did not want to Xell hack it, would I still be able to retrieve the data on my NAND chip with the lastest NXE update? I would like to back up my NAND before I actually get banned. I don't want to be HDD crippled.

Would the JTAG wiring only be necessary for the Xell hack?

Are these the correct procedures?
1) Wire up the SPI section.
2) Connect parallel cable to PC with PortIO and NandPro
3) nandpro lpt: -r256 nand.bin (read: assuming I had the 256mb chip)
4) nandpro lpt: -w256 nand.bin (write back the read data IF I am banned)

let me know if I'm forgetting something or got the command wrong.

Thanks in advance!

I want to get involved in the 360 homebrew scene (for now I just need to get my feet wet). I'm working on acquiring some older, non-updated boxes to use for homebrew once the scene's efforts reach fruition, so I'll have the hardware for anything related to 360 homebrew.

While I'm quite quick in picking up things when it comes to technology, I'm having issues finding where to start in this area as hardware hasn't been my expertise in the past. I'm slowly working my way through the Free60 wiki pages (JTAG info and such), but I'm not sure if I'm missing anything along the way or if there are any other resources that would be useful to me.

Any advice?
