One day I dropped my iPhone on the floor and my front camera started showing purple dots (dead pixel). After asking Apple Store how much it costs to repair it, I decided to replace the front camera myself. long story short, I ended up replacing the LCD, the dock connector and the front camera.
The first mistake that I made is forgot to shutdown the iPhone b/c I have been using my Lumia 920 as my primary phone. So forgotten the iPhone was still on I took the screen off and started disconnect the LCD screen from the phone. After that I notice my LCD appears to be on (blank) but not responding to my touch. I had a feeling that I ripped the cable. After I reconnected everything, not only the screen doesn't turn on but my MacBook no longer recognize it.
Then I got a touch base email from iFixit and asked me how was the repair. I explained what happened and they suggested me to replace both LCD and Dock connector. They offered me a discount for those part. After some long consideration, I decided to buy the other two components knowing that I can't guarantee it would be fix.
After 4 to 5 hrs of disassembling pretty every part of the phone and reassemble everything together with the new components, I was surprised that everything works. The iPhone 5 has so many small components that I was worrying I would miss something. I guess I am proud that I got everything fit together properly.
Read all user comments from the guides and watch other online videos before attempt the fix. AND make sure you turn off the phone.
