i had my clip for almost a year and its only froze once before 7 months ago the hold for 20-30 sec reset fixed it
this time it froze on the goodbye screen and stayed that way for about 30 sec
i held the center button and pause/play button for 10 sec and it went to black screen
but it was totally unresponsive no sync to computer, not charging and the reset didn’t work no matter how long i did it
what i did was i held the center button and pause/play button and the power button while it was connected to the computer
it went into sync mode and its working like usually does
i hope this helps someone with a similar problem
