Do what @erelectronics recommends. As I mentioned in the step: I was pushing the the speaker agains the floor and then it's a little easier. Take in mind I didn't found any guide online so for me it was even more difficult as I had to find the correct way to remove those rings.

the ring needed to be twisted has a ~ shape. this shape make the twisting tighter. you to turn them CCW

completed the guide. thx. my iphone claimed the screen is not original. anyway, seems to work correct

Hi Georgios,

I also had a button that wasn’t working well. This is why I tried to disassemble it. Since these days of confinment I did it again but followed a little more, I can recommend you that you won’t see anything since it is like a laptop keyboard also you also can damage the black label that is very sticked. This 2nd time when I did this process, I melted down one button (the left arrow) and now it is deformed and I had to repair it.

Since the keys mechanism is same as on laptop keyboards, you can try to pull it up by the one side and then the other side with care to don’t damage it.

In my case, the problem was dirty under the button that was sticking the membrane each pushin. I cleaned with alcohol and a small brush and restore it’s functionality.

EN: The lateral small plastic piece is sticked to the flex of the side buttons. Take care

right. it has 4 strips of adhesive tape

The guide is incomplete as some important steps aren’t well explained or they weren’t even explained. In general, the guide is good

Thanks to the autor

If you wont put a new battery, take care how you unstick the original / old one. It’s too well glued. Heat it well by the screen side using the iOpener or simial gel back pre-heated in the MWO. Use some plastic flat too to breake the glue. The battery will get deformed. I straghted it back and it seems to keep working.

My new frame came with this glue new and covered with a plastic. I didn’t removed that plastic in case the battery is damaged while taking out and it has to be replaced.

Attention: The flex with the buttons is well sticked to the frame. Take care how you are removing it. Use a thin tool and try to release the stick with a caution to don’t damage the flex. Pull slowly the flex.

If you breake it, you won’t be able to turn on the phone
