Hikvision DS-7604NI-SE/P stuck, expert advise needed

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 !

Hello. If the splash screen freezes on the screen, it is possible that the NVR is bricked.

Any chance of unbricking it ?

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
