Step 4: Disconnect Camera Power
Unplug the camera from its power source (USB or PoE switch).
Why Downgrade EZVIZ Firmware?
While manufacturers encourage users to stay up-to-date, there are legitimate reasons why users seek older firmware versions: ezviz downgrade firmware
- Feature Removal: Perhaps the most common reason. Manufacturers occasionally strip features (such as specific local storage protocols, legacy app interfaces, or advanced video settings) in newer "streamlined" updates.
- Performance Issues: New firmware is not always optimized for older hardware. Users often report increased CPU usage, stuttering video, or overheating after an update.
- Third-Party Integration: Users utilizing advanced setups (like Home Assistant, Blue Iris, or ONVIF profiles) often find that new firmware breaks local API access or changes RTSP stream configurations.
- Interface Changes: Sometimes the user interface changes drastically, becoming less intuitive or harder to navigate on the EZVIZ app.
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.
Tools
- EZVIZ Batch Configuration Tool (Windows only)
- Download from EZVIZ support site (official tool, works for downgrade if used manually).
- Hikvision TFTP Server (advanced, for brick recovery).
- SD Card Formatter (official tool from sdcard.org).
Step 5: Troubleshooting
| Symptom | Likely cause | Fix |
|--------|-------------|-----|
| No response after power-on | Wrong firmware file | Recover via TFTP (Method C) |
| “Upgrade failed” in Batch Tool | Firmware version not older (same or newer) | Find an earlier build |
| Flashing orange LED forever | SD card not FAT32 or wrong filename | Reformatted as FAT32, use exact naming |
| Camera offline after downgrade | Network settings reset | Reconfigure WiFi via app (hold reset to enable AP mode) | EZVIZ Downgrade Firmware Guide Step 4: Disconnect Camera
Method A – MicroSD Card (easiest for most WiFi cameras)
- Format microSD as FAT32 (not exFAT/NTFS).
- Copy the older firmware file (
digicap.dav or ezviz.dav) to the SD root.
- Rename it exactly as required by your model (common names):
digicap.dav (most common)ezviz_firmware.davupdate.dav
- Insert SD card into powered-off camera.
- Power on while holding the reset button for 5–10 seconds.
- Wait 5–10 minutes – LED will flash or camera will reboot when done.
- Remove SD card after success – otherwise camera will reflash on next boot.
Step 1: Finding the Right Firmware
This is the hardest part of the process. EZVIZ does not maintain a public archive of old firmware on their main website. Feature Removal: Perhaps the most common reason
- Check the Forums: Communities like the EZVIZ subreddit, IP Cam Talk, or Home Assistant forums often have users who archive firmware files.
- Chinese Forums: Occasionally, older firmware is found on Chinese tech forums (like right.com.cn), but you must be careful to match hardware revisions.
- Identify the Version: You need the exact firmware string (e.g.,
V5.2.8).
- Pro Tip: Always download firmware that matches your specific camera model number (e.g., C6N vs. C3WN) and hardware version. Flashing the wrong file can brick the device instantly.
