Replacement Battery Sony NWD-B103 MP3 Player - Sony Walkman Bean NW-E307 MP3 Player

firmware needs to reinstall.

The only way to fix a boot error message on an mp3 player is to do a firmware upgrade. If the firmware is available you will find it on the manufacture's website. It's important that your computer still recognize the player when it's connected because the firmware will be have to be downloaded onto the player.

The firmware should be installed then connect your usb player. Follow the steps given on the web. By the way it will be better if you format your player as well during this installation.

I'm using the same model as you and I'm very glad to share you this.. hope you will try!

Hey, guys. I just fixed this problem. My mp3 cant be detected at first too. You have to hold the play button when you connected the computer. Then the computer will detected. After it be detected, update the firmware. It 100% works. and fu*k sony.

Had a similar problem with the B103F. Not sure it will work for the non F version.
Goto Sony's support site at http://www.sony-asia.com/section/support.
Search model - NWD-B103F (non F is not listed)
Look at the "latest downloads" and select the "firmware update program". (alternately you could first select the "download" section and then select the model.)
Download.
Run (without the unit plugged) and when asked plug the unit. To be on the safe side, ask it also to format the data section.
When finished, the unit should be OK.

i think that your mp3 players battery has died of use or overcharge and you need a new one so i would take it to a retailer of your mp3 player and see if they can get a new battery for you
