Hello everyone There is a Dahua NVR4216-4K recorder built in 2015. I can't reset my password on it. I have a little experience resetting Hikvision recorders using usb-ttl. The Board has a button similar to the password reset button, but nothing happens when you reset it according to the instructions. On the Board, I also soldered two connectors that are shown in the photo, but a huge number of attempts and different options for connecting the TTL Converter did not lead to success, nothing is displayed in the Putty console. Please tell me how you can reset this recorder, which connectors on the Board you need to connect, or via rs232. Thanks!
