Adolescent user is there a way to lock this player so my nephew can't download trash on it???

According to your manual, it has no lock. Try holding the UP Button as mentioned for other models.

Re: 500 songs, all gone but wont allow other downloads, "to full"

Use settings "format" on mp3 player. This will delete any hidden files. If you download in one format (say like Ubuntu) and delete them under another (say Windows), files can remain in *.trash which is hidden. To avoid this in the future, try deleting with shift+del as it will bypass the trash folder.

It doesn't belong to you - hand it in to the police.

reset user lock code with flasher box ( u can use ufs tornado or the others )

Well, if your nephew's computer is a Windows, that means you will have to restore your ipod back to factory settings to get it to work with your computer. Open itunes to the main ipod page. It should tell you that a Windows ipod has been detected in itunes and you will need to restore your ipod in order for it to work with your computer. Click ok on that message, or if that message does not appear, click restore on the ipod page. Then it should tell you that all of your information will be deleted. Click ok if you have all of the music backed up and after it restores, it should be working normally.

Hello!!

U can download the drivers thro internet ... try googling it ...ALL THE BEST!!!

The hold button has been activated - slide the bar on the left hand side of the player up once, and the lock icon should disappear. The manual with detailed instructions can be found at:
