Most Smart Pro issues trace back to the microSD card. A black screen or a hang on the boot logo usually means the card is not FAT32 or files are not at the root — reformat as FAT32 and copy the OS or trimui_tg5040.awimg again. Missing games are fixed with Refresh Roms from the MENU button; input problems are fixed in Settings → System → Calibrate Joystick. A failing or counterfeit card is a common cause, so swap to a genuine card and a good reader.
