What does the JTAG hack allow me to do?
The JTAG hack unlocks your 360 and gives full control over it.
- Linux
- Homebrew
- Use a Re-booter(Freeboot or XBReboot)

 

 

Can this be done to all motherboard revisions?
Yes, all motherboard revisions are vulnerable to this hack. But the dashboard update on August 10, 2009 patched this hack. Some consoles that were manufactured or refurbished around June/July already have the patch applied. Which is why some consoles with the 7371 kernel are not vulnerable.

Kernel Vulnerability:

8498 and Higher - Any console with a kernel 8498 and higher have been patched to stop the hack.

7371 and lower pre june2009 - Any console with the 7371 kernel or a lower version of the kernel are most likely vulnerable to the hack. 

7371 Jasper After June 2009- This is the "iffy" kernel. With this kernel you have to dump your NAND to make sure that you have a vulnerable CB. Some consoles with this kernel already have the patch applied to them and cannot be JTAG'd.

 

Exploitable CB versions:
1888, 1902, 1903, 1920,1921: exploitable xenon
4558: exploitable Zephyr
5761, 5766, 5770: exploitable falcon
6712, 6723: exploitable jasper
