Hi mate
Following your utube video the procedure looks correct however when you have reflashed you need to be connected to your tv set to follow on screen setup which need certain response via the remote, from watching the video you may have got
to that screen then simply switched off so every time you switch it on again it will require the setup procedure to be completed first.
Of late the solo2 seems to take a tad longer in rebooting I have noticed bear in mind this is a users build with bells and whistles and every update adds more to the programme which in turn slows the receiver down a little on booting
