Thanks for taking your time to look at my post. Yes, I knew that this tool only change the language in the firmware but not the region code in the flash of the NVR. I had already tried 4 different versions of english/ML firmware of 7204HWI-SH including "whoslooking" mentioned baseline firmware and I had applied the correct command "hiktools lang digicap.dav 2" with correct magic number verified. The NVR does take that firmware without the "Language Mismatch", however after the update, NVR can not load the console menu any more(mouse cursor not appear as well, right click nothing happen, the "No Video Input" still in Chinese) or can not access from web interface neither. SADP seeing its IP though with correct loaded modified firmware.The Hiktools utility can change the language flag on a firmware file so that it would not be rejected by a camera or NVR with a 'Language mismatch' error. This would allow you to load an EN or ML firmware file.
But it does not change the language flag that's configured within the flash memory of the camera or NVR.
Any other way to change the console menu language? Trying to follow this instruction 'http://diyservice.blogspot.com.tr/2014/12/hikvision-ds-7108n-sn.html' of editing file "1024x768.cfg" but stuck with packing it back to NVR with tar & lzma as NVR not recognize it with its internal tar command.
Many thanks,
