Hi wheels, congratulations on your trio stealth pro tablet and welcome to the forum. Nice to have you as a member of Android Tablets. Check this thread http://www.androidtablets.net/forum/android-tablet-q/62022-how-do-i-factory-reset-my-tablet.html. If there are no instructions for your tablet, try some of the methods for other tablets. One of them will probably work and you won't hurt anything by trying as long as the tablet has a good charge or is plugged in. I'm also moving your thread to the http://www.androidtablets.net/forum/android-tablet-q/ section for you, where more people familiar with that tablet are likely to join the discussion in case you need more help. Good luck!
BTW If you can get into the settings in safe mode, you might be able to do a reset from there.
