Hello Lyndel!
The same thing happens If I download the default configuration, I even tried with a PCF with nothing on it no devices, nada and the same problem. I can only use the soft buttons while holding the firm button 4, the hard buttons don't respond at all NEVER none of them. I was able to go to the settings pages and mute the beeping, but the pages keep changing by themselves. And if I release the firm button, again the pages keep changing. I tried downgrading the firmware two versions before with no results. I'm out of ideas.
