your true problem is not how to unroot,but how to make your phone can copy something from pc to phone.
because every body who is root his phone
still can copy all file like music,video,picture and etc.
I have THL T200 rooted and I never have issue with transfering file from or to pc
Do you see your android phone on your pc?
Maybe you have to connect it as MTP device

Don't use htc sync.
Connect your phone as disk drive
I have htc desire vc and I never use htc sync for transfer file
because htc sync often give me error

If you connect your phone as disk drive,your phone will shown in pc under removable storage. So you can copy your music pc to phone and place it in song folder directory.
Now you can play your song with player in your phone such as htc player winamp,mixing,etc
