HI all
HELP
I was stupid enough to update my NVR (dahua dh-nvr5208-8p-4ks2) as just was installing a new ipcamera and wasnt finding it. so i thought might be firmware update needed.
So i used the the ConfigTool and updated the new firmware from dahua. as it was showing up on there.
The NVR updated and then on the HDMI output it was stuck on the v4 screen for about 6 sec but then it disconnected.
It doesn't show up on Configtool now.
Doesn't show up on my network. or ipaddress on the old one.
I tried to hook monitor and nothing up.
Also no NVR has reset button too.
What can i do as im stressed out.
Thank you in advance
 
calling @Allistiarstevenson or what ever
 
That looks like a wrong fw or a big time gap firmware bricked the NVR, use serial port flash to bring the NVR back. If you are good at it, I can send you the guide files.
Also can try to press the reset button for 7-10seconds.

Hi @EMPIRETECANDY
I tried to find the reset button on outside or the motherboard. And I can't see it. Doesn't look like this has it?
Dahua dhi-nvr5208-8p-4ks2.
I have got the serial port with usb wire delivered from Amazon today.
Would love your help and guide files. And also the right and stable firmware.
If I new this would have happened I would have never updated it.
Can you please send a step by step guide to do it as first time doing this
Thanks in advance
And thanks to @Flintstone61
