Hello!

Since last week i can't use cartridges of other brands in my offijet 7720. Through the HP smart or IP-adres webservice i can not disable the cartridge protection.
Can you guys help me out?

Cartridge protection has nothing to do with not being able to use non-HP cartridges.

Okay, can you tell me what ever it is instead of cartridge protection?

HP Recommended

It's the latest firmware preventing from using non-HP ink cartridges.

 

Dynamic security enabled printer. This Firmware includes dynamic security measures, which are used to block cartridges using a non-HP chip or modified or non-HP electronic circuitry.

Is there a way to downgrade to a previous firmware to use non-HP cartridges?

HP Recommended

If you are able to find a previous version without a dynamic security feature yes.
