The Smart Pro runs its OS and data from the microSD card, so a reset is mainly about clearing the card. To fall back to stock, remove the microSD and boot with POWER while nothing is inserted; the device defaults to its built-in state. To fully reset a card-based setup, reformat the microSD as FAT32 and reflash. Within TrimUI OS you can also reset preferences from Settings.

FAQ

How do I get back to stock?
Remove the microSD card and hold POWER with nothing inserted. The Smart Pro boots back to its stock state.
Does a reset erase my games?
Games live on the microSD card. Booting with no card does not touch it; only reformatting the card erases ROMs and saves.
