I have a DH-IPC-HFW4300S which I unwisely attempted to upgrade using the Dahua tool "Firmware Kit for IPCPTZ". The tool reloaded the camera with some image, but not one that works and it left the camera semi-bricked.
I can access the camera using Telnet and the camera does respond to port 3800. However, when I try to login using the Dahua ConfigTool, the login fails even though I know the password and can use it (with the standard prefix as described in the first post in this thread) to login via telnet.
If I kill and start up /utils/upgraded from the telnet console I get the following when trying to connect from the configtool:
# /utils/upgraded

The config tool login attempt fails with the message "Login overtime" which I assume means "login timeout".
I think that if could just get logged in from the config tool I might be able to load a working image.
I'm unable to modify the i18n files described by cctv_007 earlier in this thread because they are on a ro squashfs filesystem that cannot be modified by mounting it rw.
Does anyone have a suggestion for how I can get a connection on port 3800 to try to load a different image?
