Compile xell (from free60 cvs), it'll give you a xell-1f.bin (which really is a xell-1c.bin).

Okay, so... I updated my 360 (mfg. date 2005-10-03) to 2.0.8498.0... Grrr, and I was not aware of this NAND stuff.
Any chances the guys in the future will figure out an exploit in this fw? Eventually a way to write to the bootloader?
Any way to downgrade it? Hardware or not.. It's a very old 360, maybe there's some hardware exploits? :/

I'm not rich. Nor do I have a job.
I can wait for a long time... I guess they'll eventually break the protection somehow - maybe not. This is beyond my knowledge for sure...

This has already been patched by the latest update...
Really? Please read my post again  Roll Eyes

I know this stuff will take a long time to evolve anyway, but I'm just curious Smiley I love to mod consoles and "hack" them.

I have a question, i want to use the cygnos v1 for dual NAND

But in the installation manual, they explain that is necessary to put the nand you want to flash in "NAND flash tool", with the bad sector from the cygnos nand, for generate a new nand, to ensure data are not stored in bad sector.

How can we do if the build.py script give us a nand in multiple part ?

@8bitbubsy

The latest update modifies the second bootloader so the vulnerable kernel will not boot. Keep in mind that the JTAG exploit is still running code via 4532 kernal. Unless Microsoft is stupid enough and let out another HV  privilege escalation exploit in a future dashboard (which is not likely), any updated xbox can kiss homebrews good bye... forever

@Ski-lleR

First, dump the empty Cygnos 360 NAND
Second, use build.py to build a image or use a prebuild image
Third, use the Cygnos imaging tool.Then flash the resulting image.

8bitbubsy: Your only other option is to sell your 360 on Ebay and buy another one that hasn't been updated. Ask the seller first what version the dashboard is running

do we need the Cygnos 2.0 to use the HACK. or is it possible without it ?
or is it much more easier with Cybnos 2.0 ?

I have a 360 wit 7xxx Kernel.

Hope the hack comes soon, with a precise instructions/tutorial

if you had read the thread, you'd know that you can flash using a printer port cable too.

yes you can just flash that image to a Xenon and be done with it. Smiley
Holy $#!t be right back!

I tried that image on a keyless board (no dvdrom or anything) with the resistors in place and all I get is constantly flashing center light, no RROD or anything at all. if I unplug the av cable, it responds properly with 4 reds.

You have to use a VGA Cable to get screen output.

We'll have non-vga support soon. People, start developing, stop crying, and we would have half of the problems solved already. (haha)
