Hello colleagues! I would like to ask you for help regarding DVR DAHUA DHI-XVR5216A. The devices in question were locked with an Admin Password. After overwriting the flash, the devices worked, but the serial numbers, MAC addresses, connection to the server and external P2P were lost. Is there any way to extract the passwords from the original dumps. Тhanks in advance!
