I've taken apart and re-assembled two different Incredible phones multiple times, so I feel that I'm at least a little bit qualified to comment on the process (although I'm not a hardware techie by any means!).
First, thanks to the OP for posting the video. This would have been incredibly useful had I found it before I started repairing my phone.
There are a few things I feel are worth mentioning:
- Don't forget to remove any microSD card before trying to pull off the back housing!
- In the video, there's a hand blocking the view when the large ribbon cables are detached (it also block the view of removing the trackpad...). Now most people will probably figure it out once they get to that point, but there are tabs on the sides of each cable that you're using as pull points. Having a second of those blue tools to pull on both tabs makes detaching the larger ribbon cables a little easier.
- The video doesn't really show or explain how to detach the AMOLED display ribbon cable. This is the cable on the right side of the phone in the video. It's very short and therefore has little slack to pull back and remove from the connector. In fact, I'm not sure it *can* be removed while the mainboard is still mounted. I found that it's easiest to release all four clamps and detach the first three ribbon cables (trackpad, microphone, digitzer), leaving the display's cable still in the connector (but unclamped). As you're removing the mainboard, release the bottom, left, and top and gently tilt the board so that the display's ribbon cable slides out freely.
- There may be glue or tape between the display and digitizer and front housing. On one of the two phones I disassembled the display was attached to the digitizer with a sticky black tape. I believe there's also more of this between the digitizer and the front housing/bezel. The layer between the display and digitizer came off easily for me, but others have reported great difficulty in removing the digitizer from the front housing. Many people that watch this are probably doing so for exactly that reason - they want to replace a damaged digitizer. From what I've seen the OEM housing and digitizer are sold separately, so I think the video should continue on to show how to remove the digitizer from the housing as well.
- Re-attaching ribbon cables can be harder than detaching them, in some cases. Tilting the mainboard into the display's cable seemed to help get that one re-attached without major effort. But while long enough to move around, I always seemed to be at least one hand short or a slight angle off when trying to get the digitizer's cable back into the connector. Eventually I prevailed, but it did take longer to put this back in than it did to take it out.
Again, thanks for sharing the video - I'm sure it will help countless others that need help getting started in repairing their Incredible.
