⚠️ Pay attention! The tool must be inserted into a hole on the edge of the phone's housing. Do not press too hard. It may break the tray eject mechanism.
Step 3. Open the back cover
Using a spudger or a plastic pick, carefully, around the edge, detach the back cover clips, and remove it.
Do not insert the tool deeply or bend it. Otherwise, the housing may be tampered with or damaged.
⚠️ Be careful when opening the cover from the volume and power buttons side. Thin cable and fragile buttons are straightforward to damage.
⚠️ Pay attention to the fingerprint sensor glued to the back cover from the inside.
Step 4. Unscrew the screws
