Batolight

I have very similiar problem. And now I'm not interested in some 7.7 and future versions, I just want to go back and have a maybe 5.0 software that will work correctly to me. How is possible that there is no some kind of key combination when I turn on FROG2 for factory reset. My problem is that FROG2 say me that there is no co-processor 1. Because update for it crashed during installation. Any suggestion? Thanks in advance and best regards
