Position the opening pick at the top left corner and rotate it gently to begin separating the adhesive.

Insert a fourth opening pick into the top left corner, ensuring it's at the same depth as the other picks.

• Slide the pick along the top edge, working your way towards the top right corner.
• Continue to apply gentle pressure until you've sliced through the adhesive.

• Place a fifth opening pick above the camera flash cutout.

• Do not insert too far or risk damage to the rear cameras.

• Slide the pick under the top edge of the back cover until it starts to catch on the adhesive.
• Continue sliding the pick in until you feel the adhesive fully release from the back cover.

Remove the back cover by grasping its edges.

• If the cover remains attached to the frame, use an opening pick to carefully separate it around the perimeter.

Power on your phone and test all functions before reassembling. Ensure the phone is completely powered down before continuing work.
