Excellent guide the hardest bit was getting the back off mainly because I was unclear which bit you had to try and get off and was trying to pry off 2 small slits in the side but it’s the very back seam with no gaps and you do need a thin flat widget and patience. I now have a working kindle 3 again with the help of this guide and a replacement screen from China via ebay. Some guides say remove and disconnect extra bit but this one worked fine. Tiny screwdriver and flat widget required.
