My RG405M is frozen — what do I do?

Hold POWER for about 10 seconds to force a restart. If it still hangs, let the battery drain a little, recharge, and try again.

Why won't my microSD games show up?

Format the card as exFAT or FAT32, place ROMs in the folders your front-end scans, then rescan/refresh the game list in Daijisho or RetroArch.

Most RG405M issues are ordinary Android problems on the T618. A frozen screen clears with a ~10-second POWER hold; charging faults are usually the USB-C cable, charger, or a dusty port; wireless drops respond to toggling Airplane mode or re-pairing. If games do not appear, re-check that the microSD is formatted exFAT or FAT32 and that ROMs live where your launcher (Daijisho/RetroArch) is set to look. A factory reset is the last step if problems persist. This is a DRAFT for human review.
