ok i downloaded the latest image from the google site and did ur procedure, but it keeps saying the same message, did i do something wrong?Download the appropriate factory image from Google and unzip it. In there you'll find an image-volantis-...zip file. Unzip that as well. In there you'll find a vendor.img file. Boot your tablet into fastboot mode and use fastboot to flash this - "fastboot flash vendor vendor.img".
