you cannot upgrade to 7.xx from 6.4I tried the upgrade to 7.3 just now, couldn't try it last night , but getting this message "Flashing image was not successful openatv-7.3-zgemmah7-20240106_multi.zip"
I have got a USB in the box, should I initialize it first, or should I try an earlier dated 7.3, I also chose slot 1 to overide 6.4, then option 2 Clean (just flash and start clean), is this correect, cheers tommy
