Le XBOX360 FAT con scheda madre Xenon erano rimaste fuori dai giochi quando era uscito il Reset Glitch Hack (stiamo parlando dei primissimi modelli delle XBOX360, quelle senza porta HDMI) e il problema era da imputare ad una diversa costituzione della scheda madre e dell’assenza del chip HANA, che sincronizzava il glitch dei chip con l’attuale avvio della console.

Il Team Xecuter ha lavorato duramente negli ultimi tempi, annunciando un futuro “RGH 2.0″ che dovrebbe risolvere i problemi riportati a galla dai nuovi aggiornamenti 14717 e 14719 (dopo i quali le XBOX360 FAT sono impossibilitate all’avvio di XeLL per il recupero delle chiavi CPU) e ha rilasciato una soluzione RGH anche per queste ultime, anche se non è molto semplice da implementare: coinvolge l’aggiunta di un condensatore da 47nF e la rimozione di un condensatore dalla scheda madre, è da notare anche il fatto che il Team Xecuter ha pubblicato questa procedura con l’avvertenza che il glitch e l’utilizzo della console con l’RGH è pressoche inutile: la motherboard non “gradisce” piu’ di tanto il glitch e riporta dei tempi di avvio che possono arrivare anche a 20 minuti prima di un avvio corretto.

Quindi serbiamo questa procedura nel nostro “kit di sopravvivenza” per le motherboard Xenon che magari hanno smarrito la chiave del lettore e non esisterebbe altro modo se non quello di avviare XeLL per recuperare le chiavi corrette.

Di seguito lo schema di montaggio fornito dal Team Xecuter con le sue dichiarazioni.

We are happy to finally release the Xenon RGH Hack. This is by no means meant to be used for an everyday RGH as its as bad if not worse than a Zephyr, however it does work and will be perfect for those who have a Xenon where they lost their DVD key or an unbanned key vault.




Here is the readme included with the release:




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-xecuter.com/coolrunner/install/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 towww.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.
