Bad Update

Bad Update is a non-persistent software only hypervisor exploit by Grimdoomer for all Xbox 360 models, that works on the (currently latest) 17559 software version. Combined with InvoxiPlayGames' FreeMyXe, Bad Update can be used to run arbitrary content/XEXs on your otherwise stock console.

The following games are currently supported:

• Rock Band Blitz (trial or full game):- Download Trial
• Tony Hawk's American Wasteland (NTSC/PAL/RF)

with Rock Band Blitz being preferred due to its ability to be downloaded and copied onto a flash drive.

This exploit can take many attempts to succeed (with only a ~30% success rate and at least 5-10 minutes per attempt), and arbitrary code execution will be lost after the console is turned off.

Required Items

• Una Xbox 360 (esto no funciona en consolas Xbox One o Xbox Series)
• Un almacenamiento USB con al menos 512MB de capacidad, formateado en FAT32.
• Un juego compatible de la lista de arriba.
• La ultima versión de la Bad Update para Xbox 360 - descarga el archivo ZIP para USB.
• La última versión de FreeMyXe.

Advertencia

1. Disconnect your console from the Internet (remove your Ethernet cable, delete your saved WiFi settings), and sign into a local profile. Tony Hawk: American Wasteland comes with a local profile ("Player1") that should be used, Rock Band Blitz doesn't need a specific profile so you should make your own.
2. Download the latest release of Bad Update, and extract the contents of the folder for your game (i.e. the "Rock Band Blitz" folder's contents, if using Rock Band Blitz) to the root of your flash drive.
3. Download the latest release of FreeMyXe, and rename the XEX inside the ZIP to "default.xex", and place it inside the BadUpdatePayload folder on your flash drive.
4. Insert the flash drive into your console, launch the game, and perform the game specific steps:-
   • Tony Hawk: American Wasteland: Once at the main menu select "High Score/Free Skate", if you're asked to load last game progress select "no". Continue through the menu screens until you get to the level select screen. Once there scroll to the very end of the list and select the "Created Park" option, and then "Load Park". When asked if you want to replace unsaved park, select yes. The game will scan your storage devices for save files and you should see "Hack Xbox" in the list of available custom parks. Select the "Hack Xbox" park file, after the save file is loaded select the "Play Park" option and the exploit process will begin. Set a timer for 20 minutes - if it still hasn't ran successfully in 20 minutes, reboot your console and try again.
   • Rock Band Blitz: Press to start, and pick USB storage if the storage selection dialogue pops up. Wait for the "Running exploit" text to show - if the music and/or the background stops/freezes, reboot your console and try again.
5. FreeMyXe will now show your CPU key - you should write this down/take a picture - press to continue on "OK", and then when "Yay!" when the patch has been confirmed.

¡Felicidades! Ahora puedes ejecutar código sin firmar. Puedes usar XeXMenu para ejecutar de forma sencilla otros XEXs, pero probablemente necesites usar xextool para deshacerte de todas las restricciones (este está incluido en el archivo “Tools.zip” junto con la Bad Update) - puedes hacer esto con el comando ‘XexTool.exe -m r -r a <archivo xex>’
