I tried a few days ago to do this from YouTube but these people don't tell you all the steps please help somebody!!!!!
1. Move save onto a flash drive. (must be formatted to xbox360) 2. Open the USB in the device explorer on 360rev or other programs. 3. Go to your minecraft save 4. Extract the .BIN file of your save to your desktop 5. Make a backup! 6. Go to the Minecraft tool on 360rev. 7. Open your save on the tool 8. Add what you want into your inventory (But not things that aren't in the game) 9. File > Save (it rehashes and resigns for you) 10. Go back into the device explorer and inject the save file into the minecraft folder. 11. Plug USB into xbox 12. Move save to xbox And you're done.
