Just replaced my lcd using this guide. Not easy, but doable. Took about an hour and a half. broke about half of the clips that hold the assembly in, but moved the remaining ones around so that it is secure. I recommend buying replacement clips if you aren't comfortable with that. Also, this guide says to use a Torx T5 screwdriver. Other sites say T4. It is most definitely T5. I bought the wrong one first and had to get a new one. Home Depot has an 8 in 1 Torx tool for 6 bucks that is great. Thank you iFixit for saving me hundreds that I would have spent on a new iPad!
