I don't believe thats true.

Geremia said you could guess the software key when he released the drill mod.
Why would he say that if these could never be programmed by anyone who didn't have physical access to the machine?

Oops, you're right. I stand corrected.

There is no way I can think of to glitch an untapped line by changing its frequency and causing a soft-reset via software only, in the hardware CPU. This is a reason why MS cannot do much about this besides redesign the CPU and release new hardware. There is no keys involved, there is no software involved. Read the PDF, its a hardware hack. Did the 1.5 xboxes stop being able to be TSOP flashed when the 1.6 came out? no!
At best they may be able to somehow clock the gen going into the CPU and cause an immediate fail somewhere else in the system. Enough to halt the boot cycle. But, we just hijack THAT signal and inject the correct clock to pass... They don't have too much they can manipulate so early in the boot chain software-wise.

The clpd boards should be big and fast enough to take care of anything MS can obstruct the hack with. They may need updating to work with unhacked NEWER dashboards. Current consoles and current firmwares will always work.

Now if someone else uses this hack to expose a SOFTWARE glitch in another firmware/dashboard or in the slim units (unlikely that it would be kernel level access tho) then yes this would be outdated, until that SOFTWARE glitch is patched, like sony did with the USB dongles.

Just my opinion from an electronic point of view.
Now, anyone have direction on what we can do in xell to get vendor mode?

All i am saying is one hole leads to new holes and someone may find a way using different hardware that has a higher success rate (less retries) causing this board to become extinct

This is the greatest news I've heard this year! I can forsee the XBMC or other type of media center back to xbox 360s soon.

I'm wondering what are the technical details behind the statement "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". If we can figure out the reason, probably we can increase the success rate to make it works in just one or two seconds.

Fuck YES. The guys who do this shit are amazing never thought I would run homebrew on my jasper but now its possible AGAIN! Thanks sooo much!

you raise an interesting point.

10MHZ is there and works, a bit out of that may work better. Still 5 sec vs 30 or 40 sec isnt something to go crazy over, especially if you have to add an osc circuit with a weird freq.

If you have a frequency gen you could pulse at different frequencies to see which one sent it into the best reset glitch state. Would be best if you could log the freqs to see what happens when it fails and when it succeeds.

Crazy awesome news. Hopefully this doesn't end up like the PS3. I never thought in forever that a known root key could be patched, but it was. I still don't understand that one.

I couldn't care less that my JTAG's value just dropped quite a lot, and for one reason; the homebrew/xex scene has been stagnant and slow for quite a while. This is great news, hopefully everyone will have a shot at running unsigned code now, and it will get the scene going similar to the love the original Xbox had.

Waiting for payday and the falcon timings here.

Managed to resurrect my RROD box (finally got it to spit out an error code and correct the power short! At least I didn't have to heat up the SMD station) so I figure I might use it as a test bed for this new hack.

hangover · « **Reply #68 on:** August 29, 2011, 12:44:00 AM »

So now the race is on for who can release the first modchip for this new hack.

APE · « **Reply #69 on:** August 29, 2011, 01:03:00 AM »

I can only imagine that in the next few months more and better CPLDs will be found that work for this. That 25% success rate will likely go up if my assumptions about why it is so low are correct.

Accuracy for timings sounds pretty crucial here. On a Playstation you can get away with a PIC.

This is so good,im getting a slim for back up jtag and keep my baby protected,at least my existing jtag wont have to be played as much..MS are gonna be upset.just when they think they got ontop.BAM,this comes out and destroys them.

wow look how many people already said: "i'm buying a slim now"
i'm sure M$ will be real sad to make all that money

Bloodsack · « **Reply #71 on:** August 29, 2011, 02:03:00 AM »

The thing I want to know is when can I do my xbox jtag style? I reading about whats happening and I haven't got a clue on when everyone can hack theirs? So will we need a new motherboard or chips for this hack?

tech3475 · « **Reply #72 on:** August 29, 2011, 04:13:00 AM »

So wait, will my xenon console see support in the (preferably near) future?

My understanding of the phat hack is that it just needs that pin for resetting the CPU, I didn't think HANA had anything to do with it.

God this is (insert rant here), I missed out on JTAG and now I may miss out on this hack as well.

Sooooo this boots Xell now? Sooooo all my Jaspers from dumb ass gut swappers without drive keys?

Holy Smokes Batman!

Knew things were moving cause I kept up to date on the 'glitching' thread on XBH, you know things are going well when they have a breakthrough then it goes quiet just to keep MS off the scent! You just don't know how long till its released but sometimes you just have to have faith in the top guys

Thinking MS will have to release new HW to combat this but it may have been in their roadmap anyway, not a new model as such but a new mobo revision with smaller CGPU to reduce costs/heat etc. Depends how far down the road their engineers are and how bad they want to patch this hole.

Great day for homebrew and modders, people who have the summer 09 update and no DVD key.

Thanks to the gods who spent ages on this, top work sirs!
