Hi man, I have a problem with DVR DS-7204HQHI-K1, it absolutely dead, it shows nothing at display. Only power light is on, and i can hear that it powers the HDD but it dosn't show anything at display. I can not find the device with SADP Tool. I have tried doing upgrade with tftp but it seams that the LAN port is not working also, so i cant make the connection. Im really hopeless. Thanks in advance
Then use Analysis | Checksums | Checksum-16 to calculate the new value.
