Step by step

Close MobiFlight Connector.

While it runs it holds the board's port, and the installer cannot open it.
Plug the board into this computer.

For the 3.2″ board use a USB-A to USB-C cable. A C-to-C cable does not work with that board.
Click Install firmware and choose the board's port.

3.5″ USB JTAG/serial debug unit
Choose Install, then decide about erasing.

First install: tick Erase device. It clears out the demo the board shipped with. Updating: leave it unticked, and the board keeps its panel setup and its touch calibration.
Wait for “Installation complete”, then unplug the board and plug it back in.

The board shows a splash for 10 seconds, then the panel it is set up as for 10 more — No panel configured on a new board. After that the screen stays dark until MobiFlight sends it something. That is normal. Carry on with step 3 of the setup guide.

The board is not in the list. Try another cable; some carry power only. On the 3.5″ board, unplug it, hold its BOOT button while you plug it back in, and try again.
“Failed to initialize”. Check that MobiFlight Connector is closed. On the 3.5″ board, use the BOOT button as above, then click Install firmware again.
