Do you still have the Razr Maxx HD? If so, you *should* be able to find them by installing the app Astro File Manager. Go to the top folder, look for system, them media, then audio. They should be in there, and you should be able to copy them to storage/SD card. From there, you can copy them (long press each file you want to select, or there is, I believe, a "select all", then a "copy" button will appear on the bottom) into a folder called "notifications", "ringtones", and "alarms", for each of those types of tones. You'll see them stored in the Razr Maxx HD that way.
