Update Gone Wrong - Possibly Bricked

[yorkie]

Hello,
I am new here but have tried for an answer elsewhere and had no replies.

Basically I have an IP PTZ which is kinda old and is a rebadged Dahua SD6982 / SD6982A - the product label is IC Realtime ICIP-2001HD-IR however as soon as it connected to my network the identifier was "Dahua" and the WebUI interface was clearly that of Dahua products (albeit an older example, as it still required ActiveX to show video). It's kinda old but it WAS working 2 days ago before the update. I had contacted IC Realtime support who offered me a firmware file, but it showed "UPDATE FAILED" and I then eventually had to use the manual reset button on the camera body and then navigate via the IPv6 address to access the webUI again - however the camera would still show a video feed via the local CVBS connection and eventually I regained access to the WebUI.

I contacted tech support again and they provided a different file to update, and this time round it has completely screwed up the unit.... the unit still does it's normal startup procedure, but there is NO local CVBS video feed and it's network connections are dead. Using "Advanced IP Scanner" utility finds the unit as "Zhejiang Dahua Technology Ltd" on both 192.168.1.108 AND at 192.168.4.48 but shown as 'dead'. I have tried Telnet to both those IP addresses to check if ports 3800,42323,443,and 25 were open but get "connect failed" on each instance. I have tried nmap command "nmap-p-0-65535-192.168.4.1 192.168.1.108" and "nmap-p-0-65535-192.168.4.1 192.168.4.48" which I believe scans for all open ports at 192.168.1.108 and 192.168.4.48 but it comes back "Note: Host seems down. If it is really up, but blocking our ping probes, try -Pn. Nmap done: 1 IP address (0 hosts up) scanned in 3.37 seconds"

The camera still receives PTZ commands over the RS485 Bus - though only on Pelco-D (9600) despite setting the DIP switches to Pelco-P. There is a jump link marked "DEBUG" which I have connected, but I'm not sure what the next step might be in that regard.

Is there any method at all in which to get this camera operational in any manner, either through a direct network crossover connection or even if only available using RS232/RS485, or do I have something that USED to work but thanks to the "technical support" staff is now just a pointless lump of metal??

Thanks in advance

A small update on the situation...

doing an nmap scan of 192.168.1.108 using standard "-p-" command brings up a dead result.
doing the command "nmap 192.168.1.108 -Pn" brings the following result:

"

Nmap scan resport for 192.168.1.108
Host is up (0.0019s latency).
Not shown: 999 filtered TCP ports (no-response)
PORT    STATE    SERVICE
53/tcp    open    domain

Nmap done: 1 IP address (1 host up) scanned in 7.10 seconds

so it looks like ONLY port 53 is open for network communication via TCP... so what would be the next stage in order to access the file structure or at least set certain variables in order to open other ports such as port 80, and to activate the local CVBS video feed?
