You can't take any OTA with root or any other system modifications done. You could potentially brick your phone. So I would advise you not to take the ZVD update. Go stock first before you try it. I spent a whole day fiddling with mine after I made that mistake by accident. If you have a custom recovery, there is a thread somewhere with a flashable rom with the new update, but you have to flash the kernel separate. I can find the link if you do.
Hope that clears things up for you!
