I have a Clip+ with issues. It always worked fine. Then it became completely unresponsive to the power button or connection to computer (Windows XP). After many cycles of pressing power for 30+ seconds it finally would be recognized by the computer if I pressed the center button while plugging in in.
I’ve tried updating firmware several times using the updater utility. It typically (but not always) completes the download fine and tells me to disconnect to complete the process. When I disconnect, it always hangs. Either it just says “Disconnected” or it freezes showing some other part of the display. Then I have to hold down the power button for 20 - 30 seconds to shut it off, and another 30 seconds to reset it, otherwise it won’t reconnect to computer.
Over a couple of days of trying this, it has gotten somewhat more responsive. Once I was able to access the device menus and I reformatted the internal memory. That appeared to be successful. However, it still won’t update firmware or even turn on reliably.
Anything else I can try?
