Amiko mini hd viaccess

Hi
I have amiko mini hd and i'm trying to decode channel encrypted with viaccess
I have tried to save working key to firmware or insert it from receiver menu
But can decode the channel the key is 100% working i can see the key in receivers keys menu but cant decode channel
I have tried both firmwares emu and mcas version
Is it possible to decode channel in viaccess ?
with biss key i have no problem i an see channels
The receiver supports only biss key and no other ?

Thank you in advance
