    Unfortunately the Walkman menu does not appear after the reset. It writes only "walkman" some points are rolling on the display but after short time it stops rolling and the device hangs. The USB connection to the PC does not work as well (it worked earlier on). There was no physical demage, it looks like overloaded by the volume of files I loaded before learning about the limits of 2000 files. Please help if you can!

I suggest that you reset the Player and try. If the issue persists, you may have to backup all the songs and perform format. Format will delete all the contents in the player and later you can transfer the required songs.
To reset, keep the player on and press the reset button near the strap hole. To format, please select Settings, Common settings and select format. NOTE: take a backup before formatting and also don't format using the computer

    I'm sorry that Sony has not released any firmware update to resolve the issue. If the issue still persists after formatting the walkman player, the unit may require service.

My digital music player nwz-b135f give me boot error then became shudown what is the prolem and how i can solve it plz help me

Please check and see if the player can be reset using the reset micro switch. If not connect to the PC and see if this is detected , if not the player memory can be corrupt, it is possible that there are corrupt files- virus- within the memory and so it is hanging up the player. You can download and scan for virus in your PC, now format and reload only with safe scanned files.
Hope you check this out.

Cannot connect my NWZ-B135F sony walkman to my computer shows that sum hardware is attached but it do not recognise it


Check if it's properly installed.
else go to google and type in something similar to 'sony nwzb135f driver download'.
see what sites you can find that give you the appropriate downloads, then just install and after a maybe required reboot it will work just fine.

I hope this is useful, and greets,
