Unlike over-the-air updates found on smartphones, updating the ViewSonic M1 Mini remains a manual, file-based process—a choice that prioritizes stability in low-resource environments. The new firmware update procedure is methodical but accessible. First, the user must visit the official ViewSonic support page and download the .bin firmware file onto a FAT32-formatted USB flash drive. Crucially, the drive must be 16GB or smaller, as the M1 Mini’s bootloader cannot recognize exFAT or NTFS partitions. After placing the file in the root directory, the user powers off the projector, inserts the USB drive into the service port (distinct from the standard media USB port), and then holds the "Power" and "Volume Up" buttons simultaneously for ten seconds. The LED indicator will flash amber, signaling the bootloader’s activation. Within three minutes, the projector will reboot twice—first to flash the new firmware, then to clear the volatile cache. A successful installation is confirmed by a new on-screen menu option: "System Info" now displays the updated version number. Double-check that your USB drive is formatted to FAT32

Note: Do not put it inside a folder, or the projector won't see it. 🚀 Installation Steps
