My Nextar MA797-BR was lost for 3 months & now the battery won't charge. I can't find a way to open the casing to get to the battery & don't know what kind of battery it needs. The Nextar email help people just tell me the battery is dead, but never elaborate on how I can replace it.

Try reflashing the firmware for your device you can find the latest firmware and flashing utilities from the manufacturer?s website. Make sure that you back your music up first because when you do this you are setting it back to factory settings.

SOURCE: how do i put videos on my nextar MA797-20 MP3

Hi,

Video files need to be converted into the correct format in order to work on the player. This Nextar uses the AVI format for video and you will need to ensure that you have converted your files into this format.

For a good breakdown on how to do this and a link to a free AVI convertor please view this FixYa Tip. Video issues are discussed at bottom of that page.

Thanks for using FixYa.

hi what you need to do is check what format the music is you trying to put on their then you need to convert it to mp3.
Most often its wma so you need to convert these files to mp3 your best option is using google and type in convert music from wma to mp3
this will then list loads of sites that will convert the music for you for free then transfer these to your mp3 player then you should find they will all work
