Softening up the adhesive in the oven?

You are going to want to heat the iOpener for one minute on the highest power setting. Do confirm whether or not you are using the gel-filled iOpener or the older iOpener. If you are using the new gel-filled iOpeners, then heat the iOpener for only thirty seconds. Throughout the repair procedure, as the iOpener cools, reheat it in the microwave for an additional 30 seconds at a time. Due be careful not to overheat the iOpener during the repair and always wait at least two minutes before reheating the iOpener.

Hope this helps and please keep us updated on your repair.

I have done this several times with a Microsoft Surface Pro 3 and 4. With this technique I am able to easily remove the display assembly without damaging the display or device. I have not used an iOpener, but I have used a hair dryer and a heat gun. Hair dryers do not work well because they do not heat quickly and thoroughly enough. Heat guns work better than hair dryers, but require constant reheating as you work your way around the edges. I like the oven because it heats uniformly all the material including the frame under the glass. With this technique, I can remove the display assembly in about 1 to 2 minutes without breakage before the adhesive begins to re-harden. When I first used this technique in 2018, I used a cookie rack and cookie sheets to protect the device from the direct heat of the oven’s heating elements and to ensure ambient heat to thoroughly heat all the material. Since then I have made a ‘heat box’ out of an old Dell desktop.
