If an update broke your device, to the previous stable firmware is the logical fix. But here is the catch: EZVIZ’s official apps (EZVIZ Studio or the mobile app) do not have a "Downgrade" button.

Remember: Only downgrade one version step (e.g., 5.2.9 → 5.2.8). Jumping from 5.3.0 back to 4.0.0 will almost certainly brick your device. Updated September 2025
