Ezviz Downgrade Firmware Exclusive [ Web RELIABLE ]

Downgrading firmware on EZVIZ cameras is often pursued when new updates accidentally disable useful features like RTSP or ONVIF support, which are essential for connecting the camera to third-party Network Video Recorders (NVRs).

Since the official mobile app only supports upgrades, a downgrade requires using the EZVIZ PC Studio software and a specific "Advanced Mode". ⚠️ Essential Precautions

Risk of Bricking: Installing incorrect firmware can permanently disable your camera.

Stability: Always use a stable power source and, if possible, a wired LAN connection during the process.

Verification Code: You will need the 6-digit verification code (found on the camera's sticker) to access advanced settings. Step-by-Step Downgrade Guide 1. Preparation: Get the Right Tools

Download EZVIZ Studio: Install the desktop version of EZVIZ Studio from the official EZVIZ Download Center.

Acquire the Firmware: You must find an older .dav firmware file specific to your camera's model (e.g., C6N, C3A).

Note: EZVIZ does not publicly host older versions. Many users find these on community forums like IP Cam Talk or specialized local support sites. 2. Enable "Advanced Mode" in EZVIZ Studio ezviz downgrade firmware

By default, the upgrade/downgrade menu is hidden. To reveal it:

Navigate to the installation folder of EZVIZ Studio on your PC (usually C:\Program Files (x86)\EZVIZ Studio\config). Find the file named AppConfig.ini and open it with Notepad. Add the following lines under the [LocalOperation] section: Show=1 Use code with caution. Copied to clipboard Save and restart EZVIZ Studio. 3.

Why Downgrade EZVIZ Firmware?

There are a few reasons why you might want to downgrade the firmware of your EZVIZ device: Stability issues : If you've upgraded to a

  1. Stability issues: If you've upgraded to a newer firmware version and are experiencing stability issues, such as frequent disconnections or crashes, downgrading to a previous version might resolve the problem.
  2. Compatibility issues: If you've upgraded to a newer firmware version and are experiencing compatibility issues with other devices or software, downgrading to a previous version might resolve the issue.
  3. Features removal: In some cases, newer firmware versions might remove certain features or change the user interface in ways that you're not comfortable with. Downgrading to a previous version might restore the features or interface you prefer.

How to Downgrade EZVIZ Firmware

Downgrading the firmware of an EZVIZ device can be a bit tricky, and it's essential to follow the correct steps to avoid any potential issues. Here's a general outline of the process:

  1. Check the current firmware version: Log in to your EZVIZ device and check the current firmware version.
  2. Find the previous firmware version: Visit the EZVIZ website or contact EZVIZ support to find the previous firmware version that you want to downgrade to.
  3. Download the previous firmware version: Download the previous firmware version from the EZVIZ website or from a reliable source.
  4. Prepare a computer and a USB drive: Prepare a computer and a USB drive with enough free space to store the firmware file.
  5. Disable any security software: Disable any security software that might interfere with the downgrade process.
  6. Update the firmware: Use the EZVIZ firmware update tool to update the firmware to the previous version. The tool will guide you through the process.

Important Notes

Before downgrading the firmware of your EZVIZ device:

  1. Backup your data: Make sure to backup any important data or settings before downgrading the firmware.
  2. Device compatibility: Ensure that the previous firmware version is compatible with your device and any other devices or software you're using.
  3. EZVIZ support: If you're not comfortable with the downgrade process or encounter any issues, contact EZVIZ support for assistance.

Part 3: How to Find the Correct Older Firmware

This is the hardest step. Ezviz does not maintain a public archive of old firmware versions. Here is where to search:

Method A – MicroSD Card (easiest for most WiFi cameras)

  1. Format microSD as FAT32 (not exFAT/NTFS).
  2. Copy the older firmware file (digicap.dav or ezviz.dav) to the SD root.
  3. Rename it exactly as required by your model (common names):
    • digicap.dav (most common)
    • ezviz_firmware.dav
    • update.dav
  4. Insert SD card into powered-off camera.
  5. Power on while holding the reset button for 5–10 seconds.
  6. Wait 5–10 minutes – LED will flash or camera will reboot when done.
  7. Remove SD card after success – otherwise camera will reflash on next boot.

Ezviz C1C / C1S (Older 1080p models)

  • These are the easiest to downgrade. Use digicap.dav method.
  • Known good stable version: V5.2.3 build 180413.

8. Recommendations for organizations

  • Treat firmware integrity as part of security posture; include in vulnerability management.
  • Subscribe to vendor advisories and maintain an update/test cadence.
  • Use devices from vendors who provide signed firmware and secure update mechanisms.
  • Implement monitoring rules to detect firmware rollbacks and anomalous device behavior.
  • Train IT/physical security staff on safe recovery procedures and risks of manual flashing.

6. Mitigations and best practices

  • Maintain an asset inventory with model, hardware revision, and firmware version.
  • Restrict physical and network access to devices (VLANs, ACLs).
  • Enforce authenticated provisioning: require signed firmware and secure update channels.
  • Disable unnecessary services (Telnet, FTP) and change default credentials.
  • Monitor firmware versions and alert on downgrades or unsupported versions.
  • Keep firmware up to date; test updates in an isolated environment before roll-out.
  • Retain backups of device configs and known-good firmware for recovery.
  • Use endpoint security and network segmentation to limit damage from compromised cameras.
