That's what I did. My box now has the same f/w, loader and minicom version as your box. Randomly I get the message 'This service is scrambled or no signal present' on the screen. This only happens when changing channels. Only a power cycle cures it.
Please let me know if that happens to you.
FWIW, when I say randomly I really mean that, it can work for several days before it happens.
Of course there is always the possibility I have a genuine intermittent fault. Other people have reported that they loose all channels whenever they perform a scan. I never have, and I have scanned several times. I receive all available channels.
