Highly recommend putting books (a few pounds of them) on it on a hard flat surface after installation of the new adhesive, for at least 30 minutes. As long as everything is lined up properly between the rear cover and the phone, it should go back to being nearly perfectly flush (no gaps for water to get in).
I was able to find it on their site here, but it also comes with the bezel assembly too. You might be able to find just the camera glass on another site for sale by itself. Just make sure to choose the correct color that matches your phone, if you buy their kit.
Check out their guide they have up now for the replacement of this adhesive. Specifically, take a look at the pictures in step 10 to see where the little pieces are supposed to go.
Ditto. I ended up cracking my glass using the iOpener method as well. After no ordering and replacing the rear glass as well now, I am resorting to only using isopropyl alcohol from now on. No matter how hot I got the iOpener, how long I let it heat soak the adhesive, or how many times i reheated the iOpener and reapplied it, I never got any of this adhesive to come off without a risky struggle. And upon ordering all the adhesive kits, I still was shipped missing pieces of adhesive (camera, fingerprint reader, specific support adhesive, etc.). Very frustrating and time consuming process; far more than what these guides say it takes.
I’d highly recommend skipping the iOpener all together and just buy some isopropyl alcohol (found at most Walgreen/RiteAids/Walmarts) and some q-tips instead. Even with the iOpener as hot as they say to get it and hours of letting the heat soak into the adhesive, I still ended up cracking my rear panel glass in the corners, which makes removal even harder/dangerous with shards of glass falling off.
You shouldn’t need to, as long as it still works and the ribbon cable isn’t damaged. You will need to remove it from the rear glass panel and transfer it to the new rear panel you’re installing. Word of caution though: you have to buy the fingerprint sensor replacement adhesive separately as it doesn’t come with the rear glass panel adhesive kit. This seemed a bit misleading to me, but I found out the hard way and ended up having to buy some tape locally to get it done. I’m not sure why they don’t include it in the kit, since the camera and flash adhesive is included.
I personally used isoproyl alcohol (and avoided the iOpener) to remove the fingerprint reader carefully. I also avoided separating the fingerprint reader from its circuit board assembly, because otherwise there is another gasket you’d have to replace.
Definitely use isopropyl alcohol instead of the iOpener. Wait 10-15 minutes after using the alcohol. The iOpener does not reach high enough temperatures for long enough to significantly weaken the adhesive properly. Worked on it for hours (followed the guide to a T) and still cracked my glass to figure this one out. Don’t make the same mistake (same goes for the battery adhesive as well, use a syringe and isopropyl alcohol as well for that one too).
