Introduction

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

    • Heat an iOpener and apply it to the right edge of the back cover for two minutes.

    • A hair dryer, heat gun, or hot plate may also be used, but be careful not to overheat the phone—the display and internal battery are susceptible to heat damage.

    I try to find the correct celsius value to heat the bag or direct temp to the sides of the phone. A reference should be a good thing to have. I have a heat bed I use to heat it up. I think 80c can work

    • While you wait for the adhesive to soften, note the following:

    • There's adhesive securing the back cover around the perimeter of the frame.

    • The adhesive is strongest in the bottom right and top left corners.

    • Apply a suction handle to the back cover, as close to the center of the right edge as possible.

    • Pull up on the suction handle with strong, steady force to create a gap between the cover and the frame.

    • If you have trouble creating a gap, apply more heat to further soften the adhesive. Follow the iOpener instructions to avoid overheating.

    • Insert an opening pick into the gap.

    • Grab and remove the back cover.

    • If your cover is still sticking to the frame, slide an opening pick around the perimeter until the cover completely separates.

    • During reassembly:

    • This is a good point to power on your phone and test all functions before sealing it up. Be sure to power your phone back down completely before you continue working.

    • Remove any adhesive chunks with a pair of tweezers or your fingers. Apply heat if you're having trouble separating the adhesive.

    • If you're using Samsung custom-cut adhesives, follow this guide.
