New Xbox 360 Hypervisor exploit (software based)

[americandadsonic]

Just tested FreeMyXe beta 3 and I'm liking it so far. Naruto Path of a Ninja I can confirm now works with beta 3. Snoopy Air Ace still not working. Still not able to copy certain games to the internal HDD. Exploit feels like it's working faster but could be luck.

Makes me wonder if using this exploit, someone has taken their read Nand using 360NandFlasher, and compared it to a real device (NandX, JR programmer) read, to see if it is really reading a correct full Nand dump. All my boxes are RGH3 already, except for a Winchester, or else I'd test it.

Yup they are

 

[BigOnYa]

Yup they are

Then yea wonder what would happen, or if will be possible to read your nand & CPU key, copy to usb, run it thru jrunner on pc, make custom nand with it, then copy back to usb, then flash it on the X360. That would be the ultimate desired result of this exploit. But can it run custom nand without soldering anything, and without bricking the console, is the question.

No because that breaks all signatures.
You need a hack like RGH to skip all signature checks

Are these temps bad?

Also, when I used FSD3 and saw the 'Auto' fan setting on the right side of the setting I thought that meant going to the right with the slider would set it to it Auto. Instead, it sets my fan at the lowest setting, and after moving the slider just a little bit back and forth my Memory temp jumped up to to 95c and I shut the console off.
That is a bad design flaw in FSD3 that need to be changed as well as a confirm option before actually applying the fan speed change instantly.

Yea should leave on auto. It will run faster when it heats up to cool itself down, as intended.

Depends how far this exploit takes us. It's doing things that were thought to be impossible a few months ago. The difference then vs now is you had to RGH your console to get the cpu keys and run unsign code. So it automatically bypassed the signatures. This time around we found a software exploit so this could still be possible.

Yea, nothing should be higher than 75° at the most.

Use Dashlaunch to adjust the fan speed. Since we're still in the winter, having it set to like 40% should be ideal, you can take it to 45% if you want, and it should get louder sp at 50% and up (only use the latter in the summer months).
I personally don't like setting it to auto, i like to control the temps with nothing higher than 65°C even in intense in-game moments..

Nothing is impossible ofc. Nevertheless, the 360's boot chain is very well secured with pretty much no attack surface. As of today, pretty much every developer is sure that there'll never be anything like a "true" softmod.

I should probably mention mine was manufactured in August 2008 so it is a Falcon v2. And for quite a long time now it has been loud for years.

And speaking of dashlaunch, I would rather stay away from that. If I accidentally installed it my system would be bricked.

The guy at FreeMyXe hinted at dash launch in the future.

 

[duffman2k]

Where did you get that information from?
I don't know for sure but I see no reason why it shouldn't work.
The developers of FreeMyXe even warn users to not write to the NAND.
They wouldn't say it, if it wasn't possible

I got no information. Im wondering if it is possible or if there is something stopping this exploit from flashing nand

I would be surprised if you could write to NAND without bricking, at least not without an additional exploit to deal with the bootloaders/security.

One idea floated on MrMario's latest video in the comments is a sleep/hibernate mode for the 360. So it would keep the 360 exploited without having to keep running it everytime you turned it off unless it was unplugged or disconnected. He doesn't think the exploit will be improved that much due to it's limitations but FreeMyXe in my opinion seems to be improving the exploit time and chances. Right now it's just getting homebrew patched to work on this exploit. I'm hoping Aurora and other projects patch and update for this exploit so we could get more useability. I also hope we can connect to the internet so we can download covers/updates.

So is playing backups possible now?

Of course! I did double-check when I first used FreeMyXe; installed a few games that I had, all of them seem to work just fine. There was Need for Speed: ProStreet, Minecraft 360 Edition, Naughty Bear, Bioshock, and a few others. This was before MrMario put his video up on how to install backups.

Temps seem average on my Trinity. Best to set it to "Auto", don't tinker with anything else as you can risk damaging the console.

Any reason why Achievements aren't making sounds in Aurora?

is they any chance any other games will be used for this exploit? im looking for the game... but its a wasteland and just empty

Why not use the demo of Rock Band Blitz?
