[TUTO] Softmod de la Xbox originale en 2026 : ENDGAME et Rocky5, sans jeu ni soudure

Since the ENDGAME exploit, the original Xbox can be softmodded without a game or a working drive, with a simple USB stick: here is the complete method in 2026.


Why it has become simple

In the past, you needed a specific game (MechAssault, Splinter Cell) and a booby-trapped save. ENDGAME (XboxDev, February 2024) exploits a flaw in the dashboard itself: it works on all versions of the console, without a game and even with a broken DVD drive. The Rocky5 Xbox Softmodding Tool (version 1.3.0, regularly updated in 2026) uses it to install the softmod.


The hardware
  • A USB stick of 4 GB maximum, USB 2.0 or 1.1 (USB 3 and larger sticks are not recognised), and a USB to controller port adapter; or an official Xbox memory unit.
  • A PC with FATXplorer, to copy files onto a stick in the Xbox format.
  • Rocky5's Softmodding Tool (link on his GitHub).

First of all: the clock capacitor

On Xbox revisions 1.0 to 1.5, the clock capacitor eventually leaks and corrodes the motherboard. If you open the console, remove it: the only consequence is having to set the date after a power cut. Revisions 1.6 and 1.6b need it to boot: don't touch it.


Installing the softmod
  1. Plug in the stick (adapter in port 2) and open Memory in the dashboard: the Xbox formats it to its own format.
  2. On the PC, open the stick in FATXplorer and copy to its root the ENDGAME files provided in the Softmodding Tool (payload.xbe, helper, trigger).
  3. Plug it back into the Xbox, switched off then back on, and open it in Memory. The screen freezes for about a minute while the LED changes colour, then the installer starts. If it stays stuck for more than two minutes, switch off and start again.
  4. Install the softmod and confirm. The installer creates a safety partition, backs up the EEPROM, installs the UnleashX dashboard, and reboots several times.

The step not to skip: backing up the EEPROM

The EEPROM contains your console's hard drive key. Without it, a locked drive is lost, and you can no longer change hard drives. Copy the folder E:\Backups\EEPROM to your PC via FTP (with WinSCP or FileZilla) and keep several copies of it.


Next steps
  • Dashboards: UnleashX is installed by default; XBMC4Gamers (2.3) is the most pleasant for games, and XBMC-Emustation comes with emulators.
  • Persistent softmod: the Persistent Softmod option deliberately puts the console into a “controlled error 16” so that all games go through the softmod. This message is normal.
  • Emergency access: hold Start + Y at boot. The Softmodding Tool's extras CD also contains BIOS (TSOP) backup and flashing tools, for experienced users only.
  • A bigger hard drive: possible with the EEPROM key and FATXplorer; beyond 2 TB, you need a BIOS such as Cerbios.
  • Your games on the hard drive: see our XISO tutorial.

The most common errors
  • The stick isn't recognised: USB 3 stick or larger than 4 GB. Use a small, old stick.
  • Stuck on the green logo: switch off, unplug, and start again after a cold boot.
  • “Error 16” after the persistent option: it's intentional.
  • Never modify the real C partition: that's what the “Do not touch anything in here” folder is for.

⚠ Warning: never lose the EEPROM backup: it's the only way to recover your console's hard drive. And only use your own games.
