Samsung YP-T10 freezes on Welcome

[azzzardo]

Hello today I unfortunately followed the indication of a forum, and I interfaced my samsung t10 with xnjb to manage it on a Mac
After deleting an mp3, it freezes on the welcome screen and no longer any sign of life, and windows doesn't recognize it as hardware.
attempts:
1) reset button, held for several seconds, and if I turn off the power it restarts with the home screen and freezes on welcome;
2) I tried discharge the battery, but it's the same

Do you think I can do something, or is it time to throw it?
thanks
