La Team Xecuter rend aujourd'hui possible la réalisation du Reset Glitch Hack (initialement réalisé par GliGli & Tiros) sur les Xbox Xenon avec un dashboard inférieur à 14717/9. Attention cependant, la version Xenon du Reset Glitch Hack est capricieuse et ne convient donc pas pour une utilisation de tous les jours. A considérer donc uniquement comme utile pour récupérer vos clés ou le KV non banni.
Pour pouvoir réaliser ce hack, vous trouverez dans l'archive les diagrammes pour la puce CoolRunner ainsi que les fichiers JED/XSVF. Pour la création du fichier ECC, il vous faudra utiliser le J-runner ou le build.py disponible en téléchargement en bas de la news.
Voici le message et les explications de la Team :
Generate your ecc image using the latest version of J-Runner and flash to your NAND (+w16 just like a regular RGH).
Program your TX CoolRunner (or whatever flavor RGH mod you are using) with the tx-xenon.xsvf or tx-xenon.jed file.
The Xenon has a capacitor on CPU_RST that was removed in later models. C7R112 (located near the xclamp under the CPU) must be de-soldered, and the CPU_RST wire from the TX CoolRunner(D) must be soldered to the left pad (non grounded pad).
A 47nf ( 0.047uf) capacitor needs to be added between PLL_BYPASS(+) and GND(-). (If you have a genuine TX CoolRunner REV B you can use the on-board by bridging the CAP jumper)
A 220-270pf capacitor should be added between CPU_RST(+) and GND(-) on the cpld. (If you have a genuine TX CoolRunner REV B this is already included in the design so not required)
An easy to follow picture guide can be found here: http://www.team-xecu.../phat_xenon.jpg
Using a TX CoolRunner Rev B, and after applying various troubleshooting measures we have had glitches ranging from instant to 20 minutes.
The debug LED should flash on for less than a second and repeat every 5 seconds. If your LED stays on or does not come on at all, it is usually because of something being wrong with PLL_BYPASS. Try different values of capacitors and wires. If you have enabled the CAP on REV B of the TX CoolRunner, simply un-bridge it and try a 47nF cap instead as per the instructions above.
If it still has not glitched after several hours, try different values of capacitors on CPU_RST of your RGH mod. A longer wire / low-loss 50 ohm double shielded cable may also help with this.
To help increase boot times and stability (on all RGH installs not just Xenon) we recommend that you try Low-Loss Double Shielded 50 ohm cable. It's very cheap to use and quite effective – so a quick shout out to www.xconsoles.com who supplied a batch of high quality cable for our development team to use. It's less than 75 cents a foot – not bad.
NOTE: Remember when programming the TX CoolRunner that the Xbox power is NOT connected and that the switch is set to PRG before you connect the JTAG cable. If you connect the JTAG cable and it is set to NOR with the Xbox power connected, it can damage your NAND-X and/or CoolRunner. When you have finished programming, switch it back to NOR and then power on the Xbox.
The Xenon Hack
Please note that this hack is not available on consoles updated to dashboards 14717 or 14719.
If you are seeing the debug led it means that the cpu is probably not crashing and the issue addressed by gligli/tiros has been fixed (This can of course be a false positive as sometimes the CPU could be crashing but the SMC restarts fine – we can never be 100% sure)
So far, this is really only useful for a one time cpu_key dump. There will undoubtedly be ways of optimizing this hack in the future and who knows, it may become a reliable glitch one day.
We would appreciate that you give as much feedback to our support forums as possible to help others achieve better results and to improve this method. For now we can leave this and go back to RGH2.0 for Zephyr, Falcon, Jasper and also of course, the Corona.

Xbox 360 Xenon RGH Hack brought to you by the Xecuter RGH Development Team
Thanks are extended to Tiros & Gligli, without your work none of this would have been possible.
A special thanks goes out to cOz – your work on Dashlaunch proved to be an invaluable contribution and we look froward to your next exciting project.
Greets: Team Jungle, Team FSD, Freeboot, Libxenon & RGLoader.
La Team Xecuter publie ce soir le build.py permettant ainsi aux personnes ne souhaitant pas utiliser de GUI (ou autre) de créer leurs fichiers ECC. Elle précise également que nitram a releasé un build.py pour le RGH Slim mieux codé selon eux et sans commentaire à la fin
Voici son message :
Here is the build.py for Xecuter's Xenon RGH Hack
J-Runner has no use for build.py as it doesn't use Python (or Nandpro) but figured there would be some guys out there who still use this method.
RF1911 for the CB-A 7375
GliGli & Tiros for the original build.py
cOz for the Universal patch
To the Xecuter RGH team – you know who you are.
