Agree with Phonesurgon, no need to disconnect the screen if properly supported. The guide was great and the repair turned out perfect. Took about 45 minutes. Thanks for the great guide.

Just finished the replacement. Went fine except the replacement part was just a bit different (from iFixit). The power button replacement cable was about 1-2mm shorter than the original so it was tough trying to make it work. I took photos, but not sure where I can upload them.
