What is iXtreme LT Lite Touch Firmware
The purpose of iXtreme Firmware is to flash an Xbox 360 DVD drive. DVD drives are flashed in order to allow "backups" to be played. How do I reduce the chance of being detected by Microsoft?
Essentially, just don't do anything idiotic. Some fools have thought it a good idea not to stealth patch a game before going on to Xbox Live. Don't do that.
Also, some people thought it would be smart to download a game before release and play it. Seriously? Do not do that!
The safest way to not be detected is to stay off of Xbox Live and keep your firmware updated. If you need to update the consoles dashboard, etc, it is recommended that you reflash back to stock firmware before doing so. Although some have reported updating their flashed consoles without problem, the goal here is to minimize ban risk. (Source
