Hello there, I have decided to re-write this guide in a more simple way but more in depth than my previous guide.
To softmod your XBOX, you will need the following:-
A Copy of Splinter Cell(Original) (Not Double Agent or Chaos Theory etc)
Kryzies NDURE Splinter Cell Files (http://myfreefilehosting.com/f/8dd136be84_3.98MB - will take link down if not allowed)
An XBOX to USB cable (Either make or borrow/rent one)
Pendrive Compatible with XBOX (Most)
Xplorer360 Software (http://myfreefilehosting.com/f/78561cb6cf_0.2MB )
XBMC files (http://ftp.endpoint.nu/pub/repository/t3ch/STABLE/XBMC-2.0.1-FINAL-SLIM-T3CH/XBMC-2.0.1-FINAL-SLIM-T3CH.rar)
Once you have all the stuff ready we are ready to go.
First off we need to format the pendrive to FATX which is a file system the XBOX can recognise. To do this insert your XBOX to USB adaptor into the XBOX. Then insert your pendrive into the XBOX to USB adaptor. Go to the Memory section on the XBOX dash. It will come up with something similar to this ' Disk Read Error all data erased' then the pendrive has succesfully been formatted to FATX. If you get something like 'Disk Inserted is damaged' then your XBOX is not compatible with that specific pendrive. Try another. Once you have formatted the pendrive to FATX continue onto the next step.
We now need to get the files onto the pendrive while in windows. Insert your pendrive into the computer and do not format it, do not try and open it from My Computer. Ignore Autoplay . Start the Xplorer360 app.
Go to 'Drive' then 'Open' then 'Hardrive or MemCard', it should find your USB FATX formatted pendrive.
Then double click on Partion 0 then in the big space to the right of it drag the folders
'5553000c' and '21585554' to that big blank space.
To get the folders you will you need to extract the softmod rar file.
Once done you may remove the pendrive from your PC.
Insert into your XBOX and go to 'Memory' and it should find some splinter cell saves, copy all these to the HDD by selecting the file ( hover over the whole actual save bit and press right and press COPY and it should copy the gamesave to the HDD, do this for each one.
Once done turn off the XBOX and insert the Splinter Cell disk.
Once your through to the main menu press 'Start Game' and it should pass you through to a profile selection menu, select 'LINUX', you will then have a screen with 'Checkpoints and Levels on. Press on the Checkpoint tab by pressing A and you should get a black screen for a bit and then a menu will appear - i tlooks like the UNLEASHX/ is a live CD kinda of. Firstly Backup the EEPROM by pressing that option. Then go back to the main menu and do Basic Install. It should ask which dashboard you want. I chose UnleashX. From that moment on it will guide you through it.
At one point it will turn xbox off/ ask you to turn the xbox off. Do it. Then turn it back on.
You will be brought back into the installer and it will continue and then eventually say 'Softmad Succesfully Installed ' or similar.
Turn the XBOX off an on again ann huzzzaaaa you XBOX is softmodded!
Now you are probably wanting to use XBMC. Well, you need to get your XBOX on the internet, easiest way it to connect a straight ethernet cable to your XBOX from your router.
Once done restart XBOX/ turn on and it should find the IP, go to the settings part of the menu, MISC, then Start FTP.
Leave your XBOX alone and go to your PC, I reccomend using FlashFXP as it is much much better than the integrated FTP app for windows. type in the IP address that came up on your XBOX in the corner on the right of the screen, and use the username and password 'xbox' .
Once connected, copy the XBMC folder over to E:APPS .............. once it has been sent, go back to your XBOX and go to Apps. If it is not there, go to 'File Explorer' and then 'E:' and then' Apps' and then XBMC and then press A on 'default.xbe it should load in a few seconds.
Huzzah you are in XBMC, to make XBMC your default dash at startup follow this guide.http://xbmc.org/forum/archive/index.php/t-20759.html
