title_body: Upgrade Kindle 4 system from 4.1.3 to 5.6 I haven't found a way to upgrade the system of my old Kindle 4 notouch. I also have a Kindle Paperwhite and its interface is very nice, and has a great addition: vocabulary cards made from those words looked up in the dictionary.
  
  Is there a way to perform that upgrade manually, or will Amazon in one day offer that to those devices?
upvoted_answer: The firmware update page of Kindle does not list Kindle 4th generation notouch. Accoring to this answer and Amazon, your kindle is listed under 5th generation.
  
  The latest firmware version number for the Kindle 5th generation is 4.1.3 so you cannot update it to 5.6.0.
