Downgrade the firmware

This guide can be used to downgrade the firmware of the air-Q without being connected to the Internet.

Download links for the latest stable firmware:

https://updates.air-q.com/firmware/1.20.2_D_1.74/appimg.bin
https://updates.air-q.com/firmware/1.20.2_D_1.74/appimg.chk

Please perform the following steps:

1. Download both files from above (appimg.bin / appimg.chk)
2. Switch off the air-Q and remove the SD card from the air-Q.
3. Copy both files to the root directory of the SD card.
4. Insert the SD card back into the air-Q and connect him to the power supply.

The air-Q installs the firmware automatically and then restarts normal operation.
