When using Vista 64 bit operating systems the command should look like thi

CD \
CD PROGRAM FILES (x86)

When you hit enter at the last command a forced rebuild will start. No data or setting will be saved, however, they can be recovered from a previous backup.

And if this does not work for you, remove the micro SD card and sim card, and start it, if the problem persist better change it for warranty.
