Hello everyone,
I am new to this forum and I really like a lot the contents in here. What I am trying to do is to reverse the firmware 5.6.3 for the camera DS-2CD2043G0-I.
I tried with the tool from here and I was able to gather only this info:
I run the tool in this way:
I have an error which I don't know the meaning and when I run the tool in this way:
I get only a file which is named 'header_20' with inside this content:
I also run 'binwalk' on the digicap.dav file and I get this ouput without any file extracted:
At this point I don't know what to do. I know for sure that the image of the firmware is encrypted, but I don't know how to decrypt it in order to extract the firmware.
By the way I do own the camera, there is something I can do?
PS: The firmware on what I am working is 'IPC_G1_EN_STD_5.6.3_190923.zip' (you found attached to this thread).
