Hey! We've had a similar dilemma, and we solved it by connecting walkman to computer, then going into 'device manager' uninstalling the walkman, then remove it from usb port and re-connect it.

The computer will then 'recognize new hardware' and automatically re-install the walkman. Good as new!

Hope this helps!

Hi I had the same problem and I finally figured it out.
First you will have to try to connect to the computer by pluggin it in and reseting once the computer recognizes it you should be able to look at the files.
If you are able to get the device to this point;
1. create a folder on you computer it could be in you desktop or document and name it something you would remember to go to. I named mine SONY.
2. copy all the folders from your WALKMAN to this folder;
3. delete all files from your WALKMAN there are some files it will not allow you to and just hit SKIP.
4. download the Firmware update (1.02) from the SONY Suport website: http://esupport.sony.com/US/perl/swu-list.pl?mdl=NWZE436F and select your computers operating system and download the file.
5. Once you download it run it and it should re-install all the necesary files back to you device.
6. Re-start the WALKMAN and it sould work just fine now you can go back and add your music files and photos, etc...

Good luck this worked perfectly for mine.

SOURCE: how to download youtube in Sony Walkman nwz-e436f

Hi haseb,
If by "downloading youtube", you mean connecting to the internet and streaming live media from Youtube, that is not possible on this model. On the other hand, you can download Youtube videos on your computer and play them on your walkman. To do this, remember to convert them into .mp4 and decrease the resolution to 320x240 pixels - maybe using free programs like Videora http://www.videora.com/en-us/Converter/iPod/ (yes, I know yours is not an iPod, but it still works). If you want to play only the music from a Youtube video, go to http://vixy.net/ (this might also take care of your previous problem). Hope this helps.
