ktm76 0 Posted September 6, 2016 Hi, I own a DVR 8 Ch. Unknown brand but on the card it says "GM8187" In the network was not able to find a reset or firmware update. Attached are photos but the reason for the request I forced TCP and UDP ports to restart it went off power now hangs on the login screen and does not make me go further.

ktm76 0 Posted September 7, 2016 Thank you for having responded to me, as these operations of changing the settings of the DVR always do only this time I made from a networked workstation connected with the DVR and the amendment of the UTP ports; FTP; UDC; HTTP setting around 80 and I saved, but at time of writing has the power went out and now start the DVR loads the software, released the video screen with cameras for a few seconds and crashes. I unplugged the network I did various tests, but I can not, a few months ago I made backup extension * .cfg setting but I think I will have to flash the DVR and do not know how.
