Halp - DS-2CD2532F and multi-lang

[mabnz]

Hi,

I have a DS-2CD2532F (grey market, CN) I accidentally upgraded via the app, and got the old firmware mismatch error. I used TFTP to bring it back to 5.2.5 now I have the GUI back but it's all in chinese. I can see the dropdown to select another language when I login, but only chinese is able to be selected.

I've tried the MTD hack but it doesn't seem to have worked. My mtdblock5 is 01 for lang where it should be, but my mtdblock6 isn't like any of the screenshots in the mtd hack howto.

I've attached it below. Can anyone help?

my mtdblock6 isn't like any of the screenshots in the mtd hack howto.

Your mtdblock6 (assuming that's what the screenshot is) looks normal enough at first glance - but without the real data, not possible to verify the checksum etc.
It shows language=01 which is EN.

My mtdblock5 is 01 for lang where it should be,

You don't need to change mtdblock5.

Suggestion:

I used TFTP to bring it back to 5.2.5 now I have the GUI back but it's all in chinese.

Enable telnet, log in as root/12345 and use the prtHardInfo command to get the devType data.
Then follow the brickfixv2 'enhanced mtd hack' info here :

Unbrick and fully upgrade your R0 / DS-2CD2x32 IP cameras -
R0 / DS-2CD2x32 BrickfixV2 brick recovery and full upgrade tool - enhanced.

Thanks alastair - I've read a few posts from you on this forum and it appears you're a true guru!

Do I need to unlock the partition (mtdblock5/mtdblock6) before copying the new file to overwrite it?

So my prthardinfo shows lang=2 still:

devType = 38932

With reference to mtdblock6:
OK, so devType=9814 which is what shows in the screenshot.
And lang=01 at hex location 10 in the screenshot.
So both are good.
That leaves the checksum-16 value in hex locations 04, 05
Check if that's correct, if / when so, the camera should show EN menus and be fully upgradeable.

Do I need to unlock the partition (mtdblock5/mtdblock6) before copying the new file to overwrite it?

No, not while running the 5.2.5 firmware.

So my prthardinfo shows lang=2 still:

And therefore so should mtdblock6 - assuming you are not running 'hacked to CN' firmware !
