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

Note: Rollback does NOT require the OTA key.

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.

How It Works

The ISOBUS Block has two firmware storage slots:

• One slot runs the current firmware
• The other slot keeps the previous firmware

After an update, the old firmware remains available for rollback. After a rollback, the firmware you rolled back from becomes the "previous" version.

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
