Samsung Galaxy S21 Ultra Back Cover Replacement

步骤 1 Heat the back cover

• Unplug and power off your phone before you begin.
• Prepare an iOpener and apply it to the back cover for at least three minutes to loosen the adhesive underneath.
• 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 both susceptible to heat damage.

步骤 2 Insert an opening pick




• Secure a suction handle to the bottom edge of the back cover, as close to the edge as possible.
• If the back cover is badly cracked, covering it with a layer of clear packing tape may allow the suction cup to adhere. Alternatively, very strong tape may be used instead of the suction cup. If all else fails, you can superglue the suction cup to the broken cover.
• Lift the back cover with the suction handle to create a small gap between the back 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 you created.
• Slide the opening pick to the bottom left corner to slice the adhesive.
• Leave the opening pick in place to prevent the adhesive from resealing.

步骤 4
• If the adhesive becomes hard to cut, it has most likely cooled down. Use your iOpener for two to three minutes to reheat it.
• 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 opening pick in the top right corner to prevent the adhesive from resealing.

• Insert a fourth opening pick underneath the top right corner of your phone.
• Slide the opening pick along the top edge to slice the adhesive.
• Leave the opening pick in the top left corner to prevent the adhesive from resealing.
