You worked the flex cable through it's designated opening? Then take the kept gold/blue foil and attach it to the new LCD flex cable like it was attached on the old one.

The picture shows how it should like now.

You have to fix the cable that goes through the battery compartment. Use duct tape, or, if not available do it like I did: use normal tape.

Now you are done. I hope you took notes of how you disassembled the phone. You need to reassemble it now!
