I know that their have been threads on this before, but I still don't understand. I
unknowingly purchased a demo mode kindle fire from craigslist and I would like to figure out how to get it working. I have installed abd drivers and it is recognized in my devices as abd but it refuses to root through burrito root. Could anybody give me some tips on how to get it off demo mode or if anyone has ever had to do this before could you please tell me what you did.
