I would criticize this guide for one thing only, and that is the suggestion to remove the screen in the first place. The gasket and adhesive both can be fitted around the screen, and I found out the hard way that the ribbon connectors will NOT go back in their place easily, in fact, all I did was to push the connectors back in their place and try to push the plastic bar down, and the plastic broke before even light pressure. DO NOT remove the ZIF connectors, it is unnecessary and very risky.
