I have the Iconia Tab 8 HD not FHD and I am having issues flashing update zips in recovery menu when I first got the tablet everything was fine I rooted it using a SuperSU.zip when I flashed in the CMW recovery menu through my SD card but after a week i got a notice of a new update(the splitscreen update) which I couldnt instal due to an error so I assumed it was due to me rooting the device so i flashed an update zip again to restore the tablet back to its stock rom after that the Splitscreen update installed correctly, then afterwards I wanted to REROOT my tab but when trying to I notice I couldnt boot into CMW recovery menu only a regular recovery menu with black and red font word coloring so then I tried to install the SuperSU.zip again to root the tablet except this time I got a Signature Verification error and E:Failed to verify whole-file signature in /cache/sideload/package.zip how do I fix this please help me!!!

So its impossible for me to even apply update.zip!

    Try with another MicroSD.

     

    by the way probably something doesn't match the signature on recovery or system build or bootloader.

     

    you must ask to the community where you found informations about rooting un-rooting your device.
