Firmware Rollback

If a firmware update causes problems, you can roll back to the previous version.

When to Use Rollback

• New firmware has bugs affecting operation
• Features stopped working after update
• Device behaves unexpectedly after update

Rollback via Web Interface

This is the easiest method:

1. Connect to the device WiFi
2. Go to http://192.168.4.1/update
3. Scroll down to the Rollback section
4. Click Rollback to Previous Version
5. Confirm when prompted
6. Device will restart with the previous firmware

Rollback is protected the same way as a firmware update.

When Rollback is Available

The Rollback section only appears when:

• A previous firmware version exists on the device
• The previous firmware is valid

If you've only ever installed one firmware, rollback won't be available.

Automatic Rollback

The device has boot failure protection:

• If new firmware fails to boot 3 times in a row
• The device automatically reverts to the previous firmware
• This prevents a bad update from permanently bricking the device

After Rollback

• Check the firmware version on Settings page
• Test that functionality is restored
• Report the issue with the problematic firmware to support

Troubleshooting
