Power off the camera, remove the microSD card (otherwise it will attempt to flash again on next boot), and delete digicap.dav from the card. Power the camera back on and perform a factory reset via the Ezviz app to clear residual settings.
This is the hardest part of the process. EZVIZ does not maintain a public archive of old firmware on their main website.
Downgrading firmware violates Ezviz’s Terms of Service. Ezviz has the right to: ezviz downgrade firmware
However, in many jurisdictions (EU, USA), there is a right to repair and modify your own hardware for personal use. You are not redistributing their copyrighted firmware, merely using it on your own device.
Do not ask Ezviz official support for help with downgrading. They will not assist and may flag your account. Power off the camera, remove the microSD card
Ezviz does not officially support downgrading. In fact, most modern Ezviz firmware versions include a security lock that prevents rollbacks. Attempting to force a downgrade carries the following risks:
Proceed with caution. If your camera is working acceptably, do not downgrade for minor annoyances. This is the hardest part of the process
For advanced users: Ezviz formerly released a Batch Configuration Tool for Windows that could push custom firmware.
Note: Newer cameras block this method unless you enable "Enable downgrade" in the hidden maintenance menu (not available on most consumer models).
Ezviz cameras look for a specific filename during recovery. The most common required names are:
Rename your downloaded firmware file to digicap.dav.
