Sander 0 Posted January 1, 2017 Hello, I've bought this NVR second hand. It *should* be a nearly new "EU" unit. There only was no harddisk present. Since I have 2 WD greens left over from my previous nas build, I was thinking this was the deal for me.... I've removed all partitions form one harddisk, and I put it in the Hikvision. A few moments after power up the unit beeps 2 times and a little later a "splash" screen appears on both the HDMI and VGA output. It's stays there and nothing happens. The rx/tx led on the front flashes now and then suggesting some data (broadcast) but that's all. Since it's second hand I have no idea what IP address it's on (cannot find it in the usual IP address ranges) so I don't know if the web interface is functional. With no harddisk present the unit behaves exactly the same. I've tried removing the backup battery; the voltage seems fine. Of course the guy I've bought it from didn't reply to my emails anymore... I would say the Hikvision should boot to it's menu regardless its harddisk' status, am I right ? I'm starting to fear the unit has a hardware problem, or someone put the wrong firmware in it. How do I determine what version I have ? SN is 468792997. Do I have a chance to recover it with TFTP ? If so, where can I get the firmware for this unit ? Any help is appreciated. Thanks !

GadgetAssistant 0 Posted January 2, 2017 Hello. If the splash screen freezes on the screen, it is possible that the NVR is bricked. Share this post Link to post Share on other sites
Sander 0 Posted January 2, 2017 Any chance of unbricking it ? Share this post Link to post Share on other sites
Sander 0 Posted January 2, 2017 And the answer is "YES" What I did to determine if it was still unbrickable: - put NVR & PC together on the same switch, nothing else connected - put pc on 192.0.0.128 - ping -t to 192.0.0.64 - power on NVR -> A few seconds after power-up I received replies, to my request indicating the NVR was "alive" (enough...) And for the unbrick: - Power off NVR and stop the ping action - Downloaded firmware for my type from the international Hikvision site - Downloaded Hikvision TFTP server from another source (google is your friend) - Put the firmware file in the TFTP folder - Run TFTP server (with the above network configuration !) - Power on the NVR and the update starts. -> A few moment later the NVR beeped 2 times and I shut down the server. The NVR rebooted into the user menu. Happy days Share this post Link to post Share on other sites
