A few months ago, I formatted my Kindle because I had plans to jailbreak it. Currently, I am on firmware version 5.16.4. I formatted my Kindle to avoid another upgrade, but I use vocabulary lookups for learning English. Today, I was about to import my lookups, and unexpectedly, they weren't even able to be set in the settings. My main question is: is there a chance to activate the vocabulary builder without signing up for my account and connecting to my network? (To prevent unexpected upgrades)
Every time I enter the library on my Kindle, a pop-up message appears: 'You must register your Kindle to view and download items from Cloud.'
