How do I downgrade an Ewon firmware?
A firmware downgrade is possible but it needs to be done with extreme cautious.
To downgrade the Ewon Cosy 131 or Flexy firmware, a recovery must be performed.
For other devices (Ewon Cosy 141, CD), it depends on the firmware your Ewon is currently running and on the file responsible for the downgrade.
