I can't get the glass back cover off using the iOpener and suction cup
Hello, I am following the instructions to replace the battery in a Galaxy S10 phone: Samsung Galaxy S10 Battery Replacement
I purchased the iFixit repair kit. I am stuck on step 2. After I lay a heated iOpener on the right side of the back cover of the phone, I try to pry up with the suction cup. It's supposed to create a small gap on the right edge where I can slide a pry tool and loosen the adhesive. However the back cover does not budge at all. would you be able to tell what I am doing wrong?
I suspect a few things. First of all, I'm not sure if I'm using the suction cup correctly. If I pull extremely hard, the suction cup pops off. However I can still pull with decent pressure before that happens.
I'm not sure about the correct technique. I have been using my left hand to push down the left side of the back cover while prying up on the right side with the suction cup. Theoretically I am flexing the back cover, and that is correct right?
Another possible issue is the back cover doesn't seem to get very hot from the iOpener. Honestly not even as hot as some previous phones I own when they were running heavy games. However the iopener feels fairly hot, only if I squeeze it a little, and I had to microwave for way longer than the 30 seconds in the instructions. I laid a book on top of the iopener and phone, which didn't make the phone very hot.
One last possibility is the previous owner of this phone had repaired it, and used very strong glue to seal the back cover. The back cover has a few blemishes.
Thanks for your time!
