My phone frame was dented in the corner. But I managed to panel beat it out from the inside using some aluminum 40mm rounded corner square section inside the bent lip of the phone. Hit the aluminum section with a hammer. Not the the faint hearted, but it worked. Cosmetically a little overcorrected but at least the new glass fits in properly.

When replacing the glass, don’t forget the top edge (power button end) needs to hook in the frame.

I used UNDU adhesive remover on the membrane. It swelled and distorted and came and recovered to original shape when the UNDU dried out. Problem is getting more adhesive to replace the existing thin adhesive.

Without the adhesive , the home button protrudes from the glass and wobbles round a lot. I used a relatively wide piece of 3M 5908 VHB tape cut out to fit, which stuck to the metal base of the home button. This is not ideal, as it makes the button harder to press, but it does seal the home button from dust and water. Some thin strips to just adhere to the membrane would be OK, but not be environmentally sealed. Next time I would use the VHB strips and tiny dots of silicone in the corners. (Syringe is good for precise silicone and the VHB tape holds everything flat and level while the silicone sets.)

Transplanting the touch ID sensor is extremely tricky, but it did work. Buying the front screen including a home button might leave the adhesive to stick the old touchID sensor to the new screen.

I always use UNDU adhesive remover instead of heat. Works great for all adhesively mounted parts. I have used on numerous iphones and an iPad. If the glue stays stuck to the right part, then it is reusable still sticky when the UNDU dries out. When used on Home/TouchID button, it made the rubber membrane soft and misshapen, but it returned to normal shape when it dried out.

3M thin VHB tape 5908 can be used to replace any needed little sticky bits.

Best product for releasing pressure sensitive adhesive is UNDU Scrapbookers Adhesive Remover (hexane). Been using it for years on many things, including iPhone 3G battery. Worked a treat. Needed about 5 drops on the “underside” of the plastic tab so it ran round the corner to the gap between the plastic/battery and the tacky adhesive. I started with 3 and added a couple more when the battery was partly loose.. Gentle firm pressure pulling up the tab. No risk. Adhesive dries out and is ready to work again on new battery.

iFixit should do teeardowns on every model. If they stop, they will lose viewers to someone else.

One day you might like to try "Undu" - scrapbooker's adhesive remover - dissolves the glue bond and then evaporates leaving glue intact. I think it's fantastic stuff - used it to remove iPhone 3G battery doing a total case replacement.

Suggest trying "Undu" - scrapbooker's adhesive remover. Brilliant stuff. (chemical = hexane) Dissolves the pressure sensitive adhesive glue bond, then evaporates leaving the adhesive still sticky for reuse. I have used it on iPhone battery with success.
