2.0.6683.0	December 4, 2007 (http://www.xbox.com/en-US/support/systemupdates/20071204-features.htm)	Fall Update. Timing attack works (dependant on CB).

Please note: you must have the kernel version 4532 or 4548 in order to be able to run Linux on your Xbox 360. If you have a newer kernel version, you will need to do the timing attack process. Manually downgrading your kernel will only work if you've dumped the NAND and removed R6T3 before updating to a newer kernel.

Kernel 4552 through 6683 (the latest) can still be downgraded using the timing attack. It depends on a vulnerable CB, either 1888, 1903 or 1920.
