You said that you can still run the Splinter Cell exploit, correct? You should have FTP access to the Xbox after the exploit loads the dashboard it uses to install the softmod. If you do have FTP access, copy over and overwrite the C: drive files with a set of stock C: files. Heimdall's Xbox Engineering Disc has the stock C: files under \StockFiles\c\ and Slayer's EvoX Auto Installer has the stock files as well but I don't remember the exact path to it. After you copy over the files and power cycle, you'll be left with a stock (but functioning) Xbox, and then you're free to install your softmod again. However, I'd recommend using krayzie's ndure softmod installer over SID5. You install it the same way via a game save.
Running the exploit just makes the screen flash white and resets the game, it doesnt actually start the dashboard or go anywhere so i can't use ftp with that method
