I changed language flag and update by Uboot

The language flag is only in the header of the firmware you are trying to load.
That does not change the language of the Chinese DVR itself.

You would need some hacked firmware to change the origin of that NVR.
It's not a model that I have seen or used.
Maybe try the original seller?

Hi, today i had exactly the same problem as John Who after an update. i tried almost everything, lost many hours in front of the PC and DVR, and in my very last try (5 seconds before i look for a big hammer and destroy my DVR in more than 100 pieces) i find a solution. i just tested with different commandas and found one working, don't ask to my why, i'm not a linux expert, but it worked!

So i used this codes and worked:

setenv ipaddr 192.0.0.64
setenv serverip 192.0.0.128
setenv bootargs console=ttyS0,115200n8 root=/dev/ram0 rw initrd=0x42000000 init=/bin/sh
setenv bootcmd 'tftp 0x42000000 uImage; update'

Hope this can help to the next one with this problem.

THANK YOU SO MUCH!
i have 7b16-HUHI-K2 and bricked by upgrading to latest v3 firmware(india support provided me a 40mb file). no user to select and only 8 cams were showing in background, everything locked, no network access.

recovered using this tutorial but the commands like help or update didn't show up, only HKVS $ in serial.

attaching what i did for fellow users...
i upgraded to v4 latest firmware to date from this link, though i live in india the firmware works fine
