Introduction

This is a prerequisite-only guide! This guide is part of another procedure and is not meant to be used alone.

Switch off your phone.
Heat an iOpener to loosen the adhesive beneath the rear glass. Apply the iOpener for at least two minutes. If you have a heatbed with precise temperature control (like any FDM 3D printer with heatbed) 45°C is enough. You might want to repeat this step several times during the rear glass removal.
A hair dryer, heat gun, or hot plate may also be used, but be careful not to overheat the phone—the AMOLED display and internal battery are both susceptible to heat damage.

I needed 4 hands to do this. And good light to see the gap.

Apply a suction cup to the back of the phone, as close as possible to the center of the right edge.
Pull on the suction cup to create a gap between the rear glass and the frame.
Insert an opening pick into the gap.

Slide the opening pick along the edge to the bottom right corner.
Leave the opening pick in its place to prevent the adhesive from resealing.
Once you have inserted an opening pick, feel free to remove the suction cup or continue to use it for a better grip during this process.

Insert a second opening pick under the bottom right corner.
Slide the opening pick along the edge to the top right corner.
If you have trouble with cutting, you can use the iOpener again to soften the adhesive.
Leave the opening pick in its place to prevent the adhesive from resealing.

Insert a third opening pick under the top right corner of the back cover.
Slide the tip of the opening pick along the edge of the phone to the top left corner to cut the adhesive.
Leave the opening pick in the top left corner to prevent the adhesive from resealing.

Insert a fourth opening pick under the top left corner.
Slide the opening pick along the edge to the bottom left corner to cut the adhesive.
Leave the opening pick in its place to prevent the adhesive from resealing.

Insert a fifth opening pick under the bottom left corner.
Slide it along the the edge to the bottom right corner to cut the remaining adhesive.

Remove the back cover.
After installing the back cover, apply strong, steady pressure to your phone for several minutes to help the adhesive form a good bond—a stack of heavy books works well.

Use a Phillips #00 screwdriver to remove the ten 3.6 mm-long screws from the motherboard cover.

One of the screws has a thin white, flush surface on top that you need to break with your screwdriver.

Insert the tip of an opening pick under the motherboard cover.
Use the opening pick to lift the motherboard cover up and release the plastic clips that holds the cover in its place.
Remove the motherboard cover.
