Its better to convert the non supported Ariza to a PS 2700, and use the Pariza 2700 files that are released soon after any ECM or PID 0106 or 0907 key change. Also they get BOTH DN and Bev. No need to use older files and get only 1 provider , when new Pariza ones have been released for 2 days, getting BOTH providers.
Make sure your Key activator and all autorolls at ON position.
If after a couple of hours it becomme scrambeld either you wait for it to come back or flip the back switch off for 5 seconds then back on again and it will restart.
