Please I need help on a semi bricked x-tab tablet. I call it semi bricked because I still get to see the android page but it doesn't get pass the page. Now I have tried flashing and reloading the firmware but all have not been successful. Whenever I launch recovery mode and try to wipe the tab or the cache, it tries to format but comes up with an error "E: failed to mount /system (invalid argument). I have tried downloaded several versions of the android 4.0.4 that was previously on the tab... but all have failed to work always giving an error "failed to verify whole file signature". I'm really fed up about everything as I have tried to run several firmware from the sdcard but all filing with the error "E:failed to verify whole file signature". Please every assistance on this would be appreciated.
