This was very daunting going in (I had flashbacks of iPhone 4 screen replacements), but turned out to be mostly a breeze. Despite the amount of steps everything inside is very modular and fastened with a minimum number of screws. Logic board module slid right out with very slight pressure on the air vents. Most difficult part was getting the DC connector out and the side clips of the logic board module back in. Much to my surprise, I had it all done in 25 mins. Excellent guide.
