Wow, it's all working now! I had the 9/2015 version with v5.3.0. When I restored I couldn't load any new firmware using
TFTP. It was exactly the same problem as nationwide. I contacted him to ask for his solution and it was really easy to fix with your software whoslooking! I only had to change the language code to 1 and I finally got the Update complete! massage in TFTP. Now I have my substream back on all four cameras, and this made it possible to watch all cameras on 1 screen without the "no resource" problem (because my dvr is a lightweight I have to watch it in 4CIF, but 1080p recording).
So thanks for sharing this firmware with us whoslooking and nationwide thanks again for replying!
PS xiaoyao, you probably have the same problem if you have a v5.3.0 camera which is made around 9/2015. So use Hiktools to change the language code to 1.
You can do this by downloading hiktools. Create a folder with hiktools and digicap.dav (version of whoslooking). Open command prompt. Navigate to the folder with hiktools and the digicap.dav (you can do this by typing cd with the map you want to navigate to, for example, if you're in C:\, you can type dir to see which folders are there and choose which one you want to navigate to (for example cd desktop), if you want to move back type cd ..)
When your in the folder with hikvision it can look like this: C:\Users\Username\Desktop\Hiktoolsfolder
Now you can type Hiktools lang digicap.dav 1 and the language will be changed to 1.
Put this digicap.dav file in your TFTP folder and repeat the steps you allready did. Now you should get update complete!
Good luck.
