Newbie here. please advise
I have this kindle:
I believe you guys call it the Kindle 4 NT?
Anyway, PDF reading is horrible, I cannot zoom properly. I've tried all the methods in this post
but nothing is acceptable. I want to try this Duokan firmware. Seems the en.duokan website is no more..
What I want to know is, suppose I mess up somehow installing the Duokan, or perhaps I don't like it and want to return my Kindle to the stock firmware. Can I do that? If so, how?
