Request Newbie to updating Kodi on Amazon Fire Box with only using box to update

[Pazza75]

My mother bought us this Amazon box about 4 years ago with Kodi already installed. For years it always updated itself. Now it won't and i don't want to mess up the box build. Using Isengard 15.2. Is there any help to update the Kodi right from the Amazon Box itself? I have all Apple products and can't plug them into computer. I feel totally lost with this. Thank you for any help or direction in this matter!!
