Before you adhesive everything back together, now is a good time to test that everything works as it should, and that your Pebble boots/vibrates etc. You can also see me reusing photos here, since I wasn't planning on making this guide when I replaced the battery in my watch - this just sort of happened later!

Also, installing that LCD Ribbon cable is a pain. Be prepared for that, and take your time as always. Use a spudger to press down and seat the connector. I found it easier to get the connector seated by moving the display to the right (2nd photo), and you can also get a side on view of the connector to check if the pins are lining up as well.
