- Format the SD card in the dashcam (or use a freshly formatted card per vendor format guidance).
- Copy the exact firmware file to the root directory of the SD card (do not rename unless instructed).
- Insert the SD card in the powered-off device.
- Power on the device and let the update start automatically, or follow the vendor’s button/menu sequence.
- Wait until the update completes and the device reboots—do not power off or remove the card mid-process.
- After reboot, verify firmware version in Settings and restore or reconfigure settings as needed.
- Record a short test clip and review it to confirm normal operation.
9. Security considerations
- Validate firmware authenticity (checksum + signature).
- Use secure update channels (HTTPS, SSH, signed images).
- Limit physical access during update.
- Revoke or rotate any credentials if exposed during maintenance.
- Audit logs of the update operation and keep them with change history.
- Apply principle of least privilege: use temporary maintenance accounts where possible.

- Power the device fully – Use the original power adapter, not just battery power.
- Insert the card/USB while the device is OFF.
- Turn on the device – The update should start automatically (LED blinking, voice prompt, or progress bar).
- Do NOT interrupt – No power loss, no button pressing, no card removal for at least 5–10 minutes.
