How to Flash Dawn Firmware on the MagicX Mini Zero 28 V2

Overview

The MagicX Mini Zero 28 V2 ships with Dawn firmware on its SD card. The most common reason to reflash is moving to a larger card. Dawn publishes one image per size (32GB, 64GB, 128GB), so going from 64GB to 128GB means flashing the matching image, not cloning.

File transfer is covered below via OpenMTP, which handles everyday drag-and-drop between Mac and device. For scripted backups of the SD card, see the follow-up article. This procedure is adapted from a community setup post on r/SBCGaming[^2].
