My Favorite Guides
One problem with the guide saying "To reassemble your device, follow these instructions in reverse order" is that some of the trivial reassembly steps get missed. Like the fact that for repairs involving disconnecting the LCD, you may need to hold the home and power buttons simultaneously for 10 seconds to get the display to light up after reconnecting items. I had tried multiple times to get the display to function, and only after doing this step did it finally come on. If this info is somewhere in the guide, or in the iFixit Front Panel Assembly package, I must have missed it. I just wish I had found this advice BEFORE I managed to break the flap on the LCD ZIF connector through repeated attempts to seat the cable "properly"...
