• Drain the battery below 25% before you start on this repair
• Power the phone off and take out the SIM tray before you open it.
• The plastic back cover is glued on. Warm the edges gently with the iOpener in short bursts, as too much heat can damage the battery, then work a pick around the edge no more than 3 to 5mm in, or you can cut the wireless charging coil, antenna or camera cables.
• Always track your screws (Phillips #00) so they go back in the right place. Draw a picture of your phone and tape the screws to it, or use a screw mat
• Always unplug the battery before you remove any other parts. Keep metal tools away from the battery, and never bend, crush or puncture it.
• Take out the motherboard bracket, wireless charging coil and loudspeaker, then unplug the display cable with the spudger. The battery and board can stay in the frame for this repair.
• Warm the screen in short bursts, then lift the old screen off the front with the suction cup, working plastic picks and an opening card under it, keeping them shallow, and feed the display cable out through the slot in the frame. Use plastic tools only, never metal, against the OLED panel.
• Clean every trace of old adhesive and glass off the frame with isopropyl alcohol, so the new screen sits flat.
• Connect and test the new screen before gluing it in: check the display, touch and in-display fingerprint reader (you may need to set it up again), and leave the protective film and stickers on until the new screen is working properly.
• Glue the new screen in with a thin line of B7000 around the edge of the frame, keeping it out of the cable slot, and hold the screen pressed flat while it sets.
• Opening the phone breaks the factory seal. Fit new adhesive (a strip of 2mm Tesa tape where the old adhesive was) when you close up the back, or the phone will lose its water resistance rating.
