- Update Process:
- Connect the thumb drive to the terminal using an OTG-USB host converter.
- Select the firmware file from the pop-up message.
- After copying the firmware to internal storage, restart the terminal to apply the update.
- Verify the update in 'Settings > About POS'.
Using a TF-Card (When Terminal is On)
- Follow the same steps as the thumb drive method.
- Note: This method is not applicable for Wizarhand Q1 models as the battery must be removed to insert the TF-Card.
