The Russian Team over at hackfaq.net is working on a ReBooter (hot-reboot of the console into a hacked 360 kernel allowing unsigned XDK software - like done for the SMC (JTAG) hack before) for the Reset Glitch Hack (RGH).

Gboot is working
Today it's not a great day, for the J-Tag owners. After some weeks with a lot of work, it is real.
Gboot is running. Gboot is the first kind of rebooter for the Glitch Hack.
Gboot ist no rebooter, like Freeboot. It can actual only boot one game at the time. Now it is a developer version, but there come a ready complete rebooter.
Ok what must you do, to play a game? You need a working Glitch Hack and a dump of the nand.
So why a dump of the nand? We create a nand image with a hacked 13599 Kernel and hardcoded gamepath.
Ok now lets go to Xell Reloaded, we put our fresh generated xenon.elf to a USB drive and plug in into the xbox.
Power on your xbox and enjoy the show.
Yes it works the first game, with a Glitch Hack.
We work hard, that you can enjoy a dashboard like the original, but actual it can only boot a default.xex an nothing other.
And now we feel sorry, for all the J-Tag owners. But guys you are out.
This is a developer version, be patience a public tool comes in a few weeks.
