Timing Attack Confirmed Working after Fall Update

Ivc confirmed on the XBH forums that he managed to perform the Timing Attack on kernel 6683 (fall 07 update) and boot back into kernel 1888:

The timing attack works on the fall update!
I just downgraded a machine with the latest 6683 kernel to 1888 using the PIC timing attack. The CB/CD sections didn't change after the update and is still 1920 after the update. This might suggest CB 1888/1903/1920 on current machines can't be changed/updated, and a newer CB can only be applied to new machines from the factory/rma.

To verify that machines with CB/CD 1888 and CE/CF 6683 could be downgraded, I ran a timing attack on another machine I had and it booted 1888 after timing attacking it for an hour. Both runs was done on Xenon (initial) motherboards.

Yes, the fuse resistor [R6T3] is in place on both machines. No major problems encountered on either machines after the update and downgrade.

Geremia posted some details about the changes he found in the new kernel:

On my early 2006 console, with R6T3 resistor removed, i see only changes in the kernel+filesystem (as usual) and probably an updated consoleravocationlist, and a few bytes increased at quite end of nand @0xFF3C00, don't know, probably some settings, don't know.
No changes in KV and in CB,CD,CE (still 1888), so games are still open

Excellent news. I've been afraid to update any of my systems for fear of this.

Yet in the back of my head I've still got this belief that MS is still trying to lull us into a false sense of security before they flip a switch and crush our hopes and dreams.

Not if they want to win over Sony (IMG:style_emoticons/default/biggrin.gif) (IMG:style_emoticons/default/biggrin.gif) (IMG:style_emoticons/default/biggrin.gif)

Give us XBMC on 360 and millions of people around the world will migrate to the new generation.

adding xbmc to xbox 360 wouldnt impact sony that much...it be nice but look at what happen between xbox vs ps2... xbox has xbmc but ps2 had the games.... ps2 wins... when it comes down to it xbox 360 vs ps3...its all about the games...

My friends, please I already asked for aid and nobody so far decided my problem. I have a Xbox 360 with version of kernel 5787, I I need to make one downgrade for 4532. I need one backup of the NAND of kernel 4532 for downgrade, somebody please?

Then start reading up on how to downgrade. You can't use someone elses dump of the NAND.
