I wrote earlier that in order to get help with firmware recovery, you need to meet several conditions.
1. take a screenshot of the software version and specify the serial number of the device.
Better in a private conversation
2. If we can help you, I will tell you the details for making donations, 10$
3. Turn on your IP camera and provide it with Internet access to perform a firmware update
