The firmware upgrade page on the support website shows how to upgrade with some videos.

To upgrade from the HotSpot web interface (method A - recommended), first download this bin file: firmware.bin. It's the same file for all In/Out net devices (version 1.x blue or version 2.0/3.0 green). Follow the instructions here.

If you can't boot your In/Out net device, you should upgrade using a microSD card (method C): first download the img file: flasher-1.x.img for version 1.x (blue net device) or flasher-2.0-3.0.img for version 2.0/3.0 (green net device), burn it to the card using Etcher and then follow the instructions here.
