Okay - I uploaded another Chinese firmware and surprisingly even better :) I only have everything in Chinese now. Except that I will do a translation Polish language and re-upload the file already translated and I will have better firmware than it was originally :)
if anyone also has the same problem with this ipc-hfw4631h-zsa camera then the China firmware is here 下载中心搜索-浙江大华技术股份有限公司
 
I'm trying to figure out a way to move the description file from one firmware to this Chinese version. I'll let you know if it works :).
Also, I tried to extract the .img files within the firmware file to modify the contents but with no luck. Do you have any idea how to deal with these .img files?
 
Hello
I managed to translate the chines description file. However, I could not pack it again to .img file. Can you help?
 
Hi, i have the some problem. Is very easy unpacking only for repack firmware is not easy. By the way I find some script for repack firmware only is some error. If I bypass this fault then I let you know. If you will find first some idea how to repack firmware and will working good please let me know. To repack firmware is problem with sum control, I don't know how to calculate for this firmware.
 
Yes, I understand only replace file inside custom-x.squashfs.img need first unpacking this file and after replace packing again and this is ino easy. This file have sum control
 
Hello
Unfortunately, the "custom-x.squashfs.img" file failed to be uploaded. I'm using the TFTP method to upload the firmware.
 
Hello
I extracted your files and applied the same methodology with the chinses bin. Please see the attached error message.

Delete this upgrade_info_7db780a713a4 file and generate it again. Then run TFTP server as administrator and try to upload firmware again.
