Hey Hookie,
Not much info you are providing there but
I will assume you actually mean a Nextbook 11a just for starters?
If so check out this page:
http/www.nextbookusa.com/download.php
Updates section -> Use the "Please select" drop down menu (for example select "Firmware downloads") -> You will now see a download option for firmware update instructions (Word.doc) and a Download link for the firmware itself
Again, this is assuming that you are actually talking about the Nextbook Ares 11A (NX16A11264)
Good luck
