http://libxenon.org/index.php?topic=145.msg614The reset glitch in a few words
===============================
We found that by sending a tiny reset pulse to the processor while it is slowed down does not reset it but instead changes the way the code runs, it seems it's very efficient at making bootloaders memcmp functions always return "no differences". memcmp is often used to check the next bootloader SHA hash against a stored one, allowing it to run if they are the same. So we can put a bootloader that would fail hash check in NAND, glitch the previous one and that bootloader will run, allowing almost any code to run.8

This hack cannot be patched
I'm curious as to why the bootloader (CB) can't be patched so that memcmp returns the actual memcmp value, and not "no difference" all the time. Unless the reason memcmp is returning no difference is because of the glitch, if so then epic win :PBut at the moment you cannot play any backup, just any applications compiled under LibXenon
Good. Doubtless there are already smart people thinking how to get FreeBOOT running though :P0 -

Indeed, I wonder how long it'll take before we see the likes of FSD on a slim? Not long given how smart some of these guys are. That really came outta the blue!0 -

Wahey
I knew it would eventually happen
downside-there goes the jtag trade with its ridiculous prices
edit-just looked at the install -thats some delicate soldering in places (makes the jtag hack look like childsplay).
But Im going to do this to my jasper once this hack matures a bit more and theres more info on it
Sickened xenons aren't compatible though0 -

finally something new to do.
I'm going to deeper study it after my dissertation. can't wait!
Hope it's going well for you docentore Thanks for the link too

A JTAG takes at least 2 hours to do between disassembly, soldering the nand, reading the nand, writing the nand, soldering the JTAG, testing and reassembly. Some boards are fussy and take much longer, I've had boards take me 5 hours trying this and that because the regular way doesn't work. This is free time, and I don't know about you but I'm not working in my spare time for free, or even remotely near minimum wage.Sickened xenons aren't compatible though
Me too, but I have Jasper I can try it on 0 -

Ordered a JTAG programmer and two C-mod boards (same ones used by the libxenon folks) so I've got one spare if anybody feels up for a challenge - PM me
*Edit: Mods - if this breaks any rules or lies borderline, then work away. I'll post it for sale on adverts instead [when it arrives]*0 -

First in line when it arrives how much did you get them for?0 -
Total price was €64 for two C-mod boards and the JTAG3 LPT programmer - USB XilinX programmers are definitely not cheap at €45+. Taking off the price of the JTAG3 cable, and splitting the costs down the middle it works out at €26.50 inc shipping each.
Obviously ordering in bulk is the thing to do as shipping wasn't cheap but there's not much point in ordering lots as I'd say there are people converting it to work on other cheaper setups and Xecutor will likely come up with a nice fancy PCB job soon. I just couldn't wait 0 -

I thought about that too but it'd be dodgy enough buying a slim mobo on ebay - never know what some guy has done to it like heatgunned the crap outta it
I have a Jasper on the latest dash I'm going to test this on, got my eye out for somebody willing to loan me their slim too :PThank you for your order.
Because of an unexpected great demand for C-Mod we have a delivery bottleneck. At the moment we can't say a deliver time.
We hope that we know more until tomorrow and inform you about a delivery time than.
Your credit card reservation has not been booked yet.
Thank your for understanding.
Best regards

FFplay360 was released - a homebrew media player based on ffmpeg that'll play 720p and they're working on 1080p too. This week just gets better!
*Edit:* With the board being out of stock I might be able to amend my order to add more people on and split the cost better. Failing that I'll just go to the supplier myself, they deal with the public but it takes a bit longer for delivery. So yeah, if you're in any way interested in jumping on the early glitch train, PM me 0 -

It's all right, I just trawled through a thread over on TX that said they've designed a Nand-x Add-on (like the Probe is an Add-on to the CK3) already. I guess the next stage is production of a few boards, testing, refinement and mass production. Should be seeing low-cost activity by then, and there'll probably be a rebooter available too 0

So TX have jumped on the glitch hack?0 -
