I just updated the firmware of my m240 (to 2.5.5A).
Now ALL MY MUSIC IS GONE!!!
After the update it rebooted, then said “rebuilding library” then “no files found”. Maybe I missed something, but I don’t recall seeing a message/note/banner/popup saying “This will delete everything”. Is there any way to recover the files? I’m kinda in a bind. I’m currently out of the States using my laptop and all my “original” music files are on my desktop at home.
