It is not necessary to remove the logic board. remove the three standoff screws and the simcard holder and push back the sim ejector pin and you can lift the logic board up about 7mm. with isopropyl to loosen the adhesive, slide a spudger under the old charge port cable you can easily slide it out. Makes the job a lot easier and quicker.
Apparently it is non magnetic so as not to interfere with the compass. The iPhone 6 has moved tis down to the bottom near the battery connector.
If you are pulling an iPhone apart, Use an ice cube container for the screws. Draw yourself a plan if you must but I have done so many, I know what bits go in which hole.
Haha! Good work around!! :)
Don't bother. It really doesn't matter.
The easiest way I have found to install the home button clip is to hold it with needle nose tweezers and slide it in from left to right, holding it at about 45 degrees. once the back cutouts are aligned, push down on the font to clip it in to place. Hope this helps. (I've done hundreds and struggled until I found this trick). ;)
Try it. If it works, you are lucky. If the phone won't start up, get a new battery.
I had success using Paddle Pop sticks instead of guitar picks. (not sure what they are called in the US). The guitar picks tended to deform and melt with the heat of my hot gun. The glue used to attach the screen is just amazingly strong! It takes a lot of patience to remove all the fragments. I have done about 6 screens now and it is a turdful job!
