The instructions were perfect and well thought out. As has been said before:
1. Print out the instruction and follow them forward for disassembly and the backward for reassembly.
2. Taking out and replacing the screws is by far the more difficult part. But having a system makes all the difference. Keep the phone vertical and draw pictures on a wide 2 inch wide piece of tape and stick the screws on the pictures you draw on the tape in the exact place where you took them out. Number the steps on the tape with them same step numbers on the PRINTED OUT instructions.
3. Be patient and carefully reconnect the connectors. Verify that there is a nice snap on each connector.
4. If you follow the instructions and are systematic, you can literally go have lunch in between steps and never miss a beat.
