Samsung Galaxy S21 Plus Charging Board Replacement

Prepare an iOpener and apply it to the back cover for at least three minutes to loosen the adhesive underneath.

Careful not to overheat the phone, as the display and internal battery are susceptible to heat damage.

• Alternatives: Use a hair dryer, heat gun, or hot plate, but monitor temperature closely.

Secure a suction handle to the bottom edge of the back cover, 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.
• 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, but follow the iOpener instructions to avoid overheating.

• Slide this opening pick along the top edge to cut the adhesive.
• Leave the pick in place at the top left corner to prevent resealing.

Insert the opening pick ~3-4 mm under the bottom left corner.

• Slide the opening pick along the left edge to slice remaining adhesive.
• Careful not to damage the power and volume button flex cable when near the power button:
