DS2CD2132-I language mismatch after upgrade to v5.4.41

lcoulon · Dec 9, 2017

Hello

I've upgraded my DS2CD2132-I to firmware v5.4.41

and now when i try to connect it through web interface, i get this message :

Access Error: 404 -- Not Found

firmware language mismatch: /home/webLib

Now, the cam is only visible with Hikavision Tools v1.2.1.2

Can you please tell me how i could get it back working ?

Presumably the camera had CCCH in its serial number?
If so, the camera is part bricked due to applying EN/ML firmware to a CN camera.
Unfortunately, there is a 'downgrade block' in the firmware of 5.4.0 and higher that will prevent you from going back to earlier versions of firmware.
If you want to convert the camera to full English to remove it's CN origins you could do the brick-fix and 'enhanced mtd hack' from here :
Unbrick and fully upgrade your R0 / DS-2CD2x32 IP cameras -
R0 / DS-2CD2x32 BrickfixV2 brick recovery and full upgrade tool - enhanced.

You are right, the cam has a CCCH serial .

I tried to follow the Brick recovery steps , but i'm facing outstanding issue after getting the cam flashed with TFTP :
I 'm able to connect it through Telnet : 192.0.0.64 with credentials but the script fails, it is not able to export any file to TFTP

Here is the log i get :

That's bizzarre!
The script is not executing normally. It's not clear to me why.
You do still have the Hikvision tftp updater running, based on your screenshot, but I don't see why that should affect the normal running of the script. It would just complain about not being able to upload any files.

Can I just check the steps carried out:
With either the brickfixV2EN.dav or brickfixV2CN.dav renamed as digicap.dav applied with the Hikvision tftp updater.
Then the tftp updater shut down, and the camera power cycled.
Then telnet access to 192.0.0.64 with admin/12345 login.
Press Return a couple of times, to confirm there is a # prompt.
Then start the normal tftp server (maybe the jounin.net one linked to).
And then, at the # shell prompt of the camera, use the command
/dav/fixup.sh

lcoulon · Dec 9, 2017

Thanks, now i was able to go ahead in next steps.

I did the checksum calculation with HxD, but the result got on the bottom of the screen looks to be the same in 0x04 - 0x05
Should i leave as it is , i did not understood was i'm supposed to do next with checksum.

Here is screen capture, no modification was made so far :

Since it looks that no change are needed in that file, i proceeded with next step :

Here is the log i get :

I do not know if all is finish or if i need to do more things .
Is it normal that "mtd6ro_mod" may not require any changes ?

So far, after a power cycle the cam is not visible with Hikavision Tools, and DHCP router did not assign an IP to it.

If it didn't need any changes - your camera would be running normally with the new firmware instead of complaining about a language mismatch.

You haven't yet changed the language byte in location 10 from 02 (Chinese) to 01 (English).
That will drop the needed checksum value in location 04 from 91 to 90.

That's normal - it will appear inert until the process is complete. It's running in min-system mode just now.

lcoulon said:

You do need to change the language byte in location 10 - and then the checksum as explained above.
You'll need to repeat Stage 2 so that you can get the correctly modified mtd6ro_mod in to the camera.
You can cheat if you use these 2 commands :

rm /dav/fixup_stage*
echo "Get me back to Stage 2" > /dav/fixup_stage2.txt

and then run
/dav/fixup.sh
again.
Then when you've done that, drop a copy of the digicap.dav that you want to update to into the working folder and run the script again, which will do stage 3.
It's looking like going straight to the 5.4.5 version works OK for the fixup script.

It's interesting that the checksum was actually correct. That, and the fact that the language byte is 02 (Chinese) explains why you just got a part brick - a language mismatch.

But I'm quite intrigued - the fixup script is working normally now - what's changed to get over the problem you saw originally?

Good luck!

lcoulon · Dec 9, 2017

Okay, i just noticed while you were probably writting back to me that i forgot to change 0x10 = 01

Here is what i did, the checksum is now indeed 90 0C

I will now try the cheat you described to redo the file transfer, i will you know the results asap.

lcoulon · Dec 10, 2017

I confirm i was able to fix the language issue, the last step ( firmware upgrade ) passed straight away at v5.4.5

Thank you very much Alistair, now my cam is rescued !

You cannot use the Hikvision tftp updater at that stage. It will only download files, not upload them.
You need to use the 'standard' tftp server for Stage 2&3, as per the step-by-step guide.
Suggested is the tftpd32 from Jounin - TFTP server
