Very strange because I tryed to upgrade the same and can't. If I do by IE it says that other platform (or something like that). If upgrade by tftp it says that unpacking error. SADP I didn't try. And if I remember correctly, after update BrickfixV2 firmware doesn't have version 5.4.41
On the link that I gave above there is a firmware 5.4.41 chinese version. Maybe you using this? I tryed to upgrade 5.4.41 chinese version and it works fine but only chinese.

Earlyer I used this brickfix for ds-2cd2032I and it work fine. Thanks Alastairstevenson for this.

Some interesting results here, in some ways.

It sounds like perhaps the Hikvision 'downgrade block' is getting in the way of reverting to earlier, working, but CN, firmware.
And that the 'brickfixV2EN/CN.dav' firmware, which is R0-based, can be used to inhibit the 'downgrade block' on these R2 cameras, which is what it does for R0. To do this it uses a modified 'min-system' runtime environment. It's this that processes the 'update' command in the bootloader.
Which then allows the earlier CN firmware to be loaded, and the camera works again, though with CN menus.
 
ok. Earlier I wrote to the sellers on aliexpress for helping. One wrote
"I think no one has such hacked firmware, coz the hacked camera cannot be upgraded
Otherwise it will back to Chinese
Sorry, we have no hacked firmware, my apology !"

Another one wrote
"Dear Customer
Please send your inquiry to tom.gate@outlook.com"

I wrote to this email and no answere. Try to write seller. May be someone give us firmware with multilanguage.
 
Ok i write to this man.... but i dont have contact with my seller. Because i delete some time ago my orders from app Aliexpress.
 
ok friends also me if I find something for this camera firmware I will share it with you!!

After restart - too many errors, loop boot. Camera doesn't work.

3.Trying to update 2xx0,2xx2,2xx4_CN_5.4.41 and change language to English via hiktools.
result is
Bytes transferred = 13712636 (d13cfc hex)
error: packet's language mismatched!
error: digicap unpack error!

4. Trying at the same digicap.dav change back language to CN via hiktools and have error:
Bytes transferred = 13712636 (d13cfc hex)
error: packet's language mismatched!
error: digicap unpack error!

5. Trying to update clear 5.4.41 CN and have loop rebooting.
6. Trying to update clear CN_STD_5.4.2_160608 and have good start.
7. Trying to update CN_STD_5.4.2_160608 and change language to English via hiktools.
Result is
Bytes transferred = 13790460 (d26cfc hex)
error: packet's language mismatched!
error: digicap unpack error!
8. Trying to get back Chinese at the same file. Result is good boot.

My thoughts:
1. digicap.dav from brickfix doesn't work
2. change digicap.dav using hiktools doesn't help
3. Immediately transition to the 5.4.41 is impossible and firstly we must update to 5.4.2 after that we can update to the 5.4.41.

I would not have expected that to work as it is for R0 series cameras. So strange about the earlier result.

It just changes the language of the header that is before the firmware - to fool the simple first part of the process that validates the firmware for update.
Useful, but does not change the language of the firmware or the camera.
 
I know that only user MonteCryptho on this forum can help us... also for R2 and G0 platform. It is user magic. But he dont answera....
 
Yesterday I unpacked digicap.dav wich is 5.4.2 Chinese and saw that it has English and Russian languages. But I don't know what I should do with this. Also I wrote to another one seller from Aliexpress but he has not answered yet.
 
Hello JohnnyKirchev I don't use SD slot but also I'm searching to find how it will be possible to change to english language but still now I didn't find nothing!!! Did you get awnser from MonteCryptho?
 
MonteCryptho user no reply for all user. I also write to him but no replay. But i write for platform G0.
