Hello, I would like to talk about the problem. My Hikvison recording devices have a password, so the BIOS is written. Our problem is the serial numbers on the devices, as written, it works in offline mode, but I cannot change it to online mode in any way. I have the BIOS. I tried to edit it, but it could not find the serial number with the BIOS hex editor. I have the original serial numbers. Can you help me? Best regards.
