I have attempted to reset this tablet and delete all personal data for resale. even reinstall the os option boots back with all my personal infom apps and account info still intact. Dell tech support says the os is corrupt somehow and wants me to pack it up and ship it back to the factory. This is not an option for me as I already have a buyer lined up. Google searches return no similar problems with other users. I have a usb recovery key sent from dell, but resetting with this still does not completly wipe the slate and all personal data returns. Does anyone have any ideas? im thinking of completly wiping ALL partitions and attempting an os reinstall with the usb key dell sent. however, i dont know if the key will have all os files needed to boot a completly new windows instalation. Any help is appreciated and thank you in advance.
