Step 3. Unscrew the screws

Okay, guys. We received this model without screws, but we see the holes and threads. So we are assuming that they are for the Pentalobe screws.

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.
