Nwd b100 boot error shutting down

SOURCE: Boot Error Shutting Down Sony NWD-B103

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.

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.
