Post a zipped copy of the firmware that you are exploring and I'll take a look at it.
Here the dav File
Ok, I'm out just now, I'll take a look this evening.
The firmware you supplied is for a device class 68 - it's neither K41 nor K51 - and I forgot to ask what the firmware was for, and you didn't say.
That means that hiktools is not quite extracting the cramfs.img correctly from the firmware wrapper - the new_20.bin file is being left on the end of cramfs.img
So hiktools cannot do the whole job of unpacking and repacking that specific firmware.
In order to do that, some manual work cutting and splicing would be needed.
Tedious - but certainly possible with care.
That is the reason i exracted header, cramfs and new_20.bin with a hex editor. In the new_20.bin there is a timestamp (2017 Jan 03 20:44:22). Just fo fun i added one second and the update fails. Could it be that i have to change the Version number which is stored in the update? Maybe the DVR saves the MD5 of the last update and checks that i want to update the same version but with a different MD5?
I combined the header from an older firmware with the new one just to look what will happen. The error "Firmware mismatch" doesn't show up. The DVR reads the firmware file till the end and then shows the error "Upgrading failed, execute program error"
So there must be another cheksum stored somewhere in the header or in the new_20.bin
@alastairstevenson: can i upload the header, cramfs and new_20.bin so that you could check that i am doing it right?
OK, go for it.
How i can do unpack firmware from DS-KH6210 and DS-KH6210-L? This tool do this? Unpack with error, and packed file not flashing on device, error: Update Failure. Firmware now 1.3. Thanks for answers.
My friend has camera DS-2CD2035-I from china with multilanguage firmware but without upgradable.
What is a platform and how i can change it to we can update firmware from official web page ?
This I believe is a G0 series camera.
I've had several of these China-region cameras with ML firmware.
They had some quite smart hacked firmware that presumably deliberately did not have any firmware upgrade capabilities.

To make changes and to upgrade, I had to use the serial console to erase the existing system and app partitions and manually apply updated tweaked firmware.
Not for the faint-hearted or non-techy types.
Can you describe me step by step how i can do it ?
A description of the steps in this thread :
Long-shot help request - Hikvision DS-2CD3335D - G0 series IPC.
can you please upload that hikpack.zip again? The link has died now
The download link seems to be broken - anyone got a working one?
Also need this link to be active...
We can add this very useful tool to the forum Resources. @Mike
In the meantime, attached is the latest version that was published here by @montecrypto
Can you describe me how i can use it to write to my DS-7608I-E2 with multilanguage from China. I want update firmware in my NVR.... to latest firmware.
It is info from my NVR

Outstanding, Sir! Thank you!
