Hi guys, I have updated the bios of my Toshiba C660 laptop but now one or two keys are not working like "z" and arrow keys etc. Now I how can I restore the previous version of BIOS.

When updating the BIOS it overwrites the current version with the new version and is not reversable unless you had made a backup of the previous version.

If you know what your original BIOS version was, and it's on Toshiba's website, you may be able to install it over the new one.
But it may not allow you to downgrade, you will have to try it to find out.
