Samsung Galaxy S21+ Back Cover Replacement

Apply iOpener to the bottom edge of the back cover for 2 minutes.

Be cautious when using a hair dryer, heat gun, or hot plate – excessive heat can damage the display and internal battery.

Secure a suction handle to the back cover's bottom edge, as close to the edge as possible.

If the back cover is cracked, try lifting it with strong tape or superglue the suction handle in place and allow it to cure before proceeding.

• Lift the back cover with the suction handle to create a small gap between the back cover and the frame.
• If trouble creating a gap occurs, apply more heat to further soften the adhesive. Follow the iOpener instructions to avoid overheating.
• Insert an opening pick into the created gap.
• Slide the opening pick to the bottom left corner to slice the adhesive.
• Leave the opening pick in place to prevent resealing of the adhesive.

Insert a second opening pick at the bottom edge.

• Move the pick towards the bottom right corner, slicing through the adhesive.
• Keep the picks in place to prevent the adhesive from reforming.

Apply iOpener to the right edge of the back cover and heat for 2 minutes.

Do not proceed if the adhesive is hard to cut as this may indicate it has cooled down.

• Reheat the adhesive with your iOpener for two to three minutes.
• Insert a third opening pick at the bottom right corner of your phone.
• Slide the opening pick along the right edge of your phone to slice the adhesive.
• Leave the pick in the top right corner to prevent resealing of the adhesive.

Apply heat from an iOpener to the top edge of the back cover for 2 minutes.

When slicing near the camera assembly, only insert ~4-5 mm of the opening pick tip.

• Insert a fourth opening pick under the top right corner.
• Slide along the top edge to cut the adhesive with the opening pick.
• Leave the opening pick in the top left corner to prevent resealing.

Apply heat from the iOpener to the left edge of the back cover for 2 minutes.

• Insert a fifth opening pick ~3-4 mm deep underneath the bottom left corner.

• Be cautious when slicing near the power button — risk of damaging the power and volume button flex cable

• Slide the opening pick along the left edge to slice the remaining adhesive, continuing carefully around the power button area.

Remove the back cover.

• Power on your phone and test all functions before reassembling.
• Ensure your phone is powered down completely before proceeding.

Be cautious when handling adhesive chunks to avoid damage or injury.

• Remove any remaining adhesive chunks with a pair of tweezers or your fingers.
• If necessary, apply heat to aid in separation.
• If using double-sided tape, consult the relevant guide for instructions.
