For various reasons, we sometimes need to downgrade the firmware of devices in our Cudy Mesh system to an older version, but this is not allowed in the "General Settings" -- "Firmware" page or "Advanced Settings" -- "Firmware" page. So how should we handle this? The following will use the M3000 as an example.
1. Please go to "System Status", click "More Details" on the Mesh card. As shown below.

2. Check the Mesh list. You can update the firmware of the Mesh devices one by one. We suggest update the satellite mesh routers first. Click the Mesh device, find the "Operation" --"Firmware".

3. Upload the firmware, then the device will be updated. You can update the next Mesh device after update successfully.
