Gaming Firmware Downgrader?

[Christopho]

Does anyone know if there's such a thing as a firmware/kernel downgrader like the Wii? I'm asking this because I want my xbox Jtag'd but it's not vulnerable sadly =/

Thanks in Advance~

no there isnt, try to buy a new one that is still exploitable, i did and very happy with it, 500gb full of games, no discs needed

There is nothing to roll back the kernel or firmware to a jtagable version at this moment in time.
(Hope some breakthrough comes soon!)

Chances of any downgrader turning up are far from likely. As mentioned every time someone asks this question, the 360 uses a form of security known as efuses. When the 360 gets updated, it blows one of these efuses (there're over 800 I believe), making downgrading impossible.

Your only hope is that someone finds a new exploit, since JTAG is generally impossible now. Or you can look on ebay for an exploitable 360 for sale. I've still got one left (I updated the other 3 long before the homebrew community took off), which I haven't got round to JTAGging yet.

To clarify, the efuses revoke the dash rev that the exploit runs on. The dash rev is nothing to do with weather or not the console is J-taggable, its just an easy indicator, as the efuse is blown by default in the update proccess on almost all updates over 2.0.7xxx.

If you still need a J-tagged unit, then I have a few here (Xenon, Falcon or Jasper)
