[Commotion-admin] [commotion-router] New Airgrid M5's unable to be flashed with Commotion (#161)

[Adam Longwill]

Meta Mesh has recently purchased a number of Airgrid M5's and has attempted to flash v1.1 on them as it has done in the past but has been unable to. This is a critical problem and essentially stalls all long-distance expansion for everyone using Commotion.

After verifying the MD5 hash from a fresh download of Commotion for Airgrid, we are unable to upload via gui the firmware, receiving the error -6 in this screenshot:

After doing a bit of research, it appears that Ubnt has changed the file format of its images specifically for the Airgrid M5: https://community.ubnt.com/t5/airMAX-Frequently-Asked/airMax-Choosing-the-right-firmware-file-for-your-device-upgrade/ta-p/907346

This makes sense with what we have seen. We have attempted to upload v1.1, rc1, a nightly build, a vanilla openwrt build, and have attempted this from gui and in tftp mode. the check fails in all builds and the only kind of upgrade that can be made is upgrades to the UBNT firmware from their site.

This is a huge issue! I hope we can address this immediately. Meta Mesh is at your disposal to assist in testing this.
