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.
