• Avoid separating the display's upper border from the back cover by forcing it, because it is secured with potentially fragile plastic fasteners.

• Using your tool, begin at the lower-right edge of the iPhone and move it along the perimeter, releasing the adhesive by sliding it along the corner and up the right side.
  To prevent damage to the display cables, limit pick insertion depth to a maximum of 3 millimeters.

• Using a gentle upward motion, disengage the display from the device by lifting its lower border with the suction cup.
  To prevent damage to the ribbon cables that connect the display, limit its upward angle to a maximum of 15 degrees.
  To detach the suction cup, grasp the small projection extending from its surface and apply traction.

1. Using an opening pick, carefully separate the adhesive securing the display by inserting it between the display and the phone's body, starting at the top-left corner and working along the entire top edge.

1. To release the display assembly from the rear case, move it downward, ensuring the retaining clips separate.

1. Using a prying tool, carefully separate the display assembly from the rear case by initiating movement upwards from the left edge, mimicking the action of opening a book's cover.
   Before completely detaching the display, avoid doing so, because delicate ribbon cables, still linking it to the iPhone's logic board, remain connected.
   To allow hands-free access during the repair process, temporarily support the display using an external object.

• Using a Y000 tri-point screwdriver, detach the lower display cable bracket from the logic board by unscrewing the four screws that hold it in place.
  
  • Use three screws, each measuring 1.2 millimeters.
  • A screw with a 2.6-millimeter head diameter is required.

• Carefully disengage the battery connector from its socket on the logic board by applying targeted pressure with a spudger tip.
• To avoid unintended power delivery and contact with the socket, gently raise the connector cable a small amount.

• Carefully separate the two display connectors from their sockets on the logic board by applying upward pressure with the flat edge of a spudger or a fingernail.
• Ensure the connector is properly aligned before applying pressure to either end until you hear a distinct click; avoid applying pressure to the central portion, as misalignment can result in bending and irreversible damage.

• Using a Y000 tri-point screwdriver, detach the bracket that covers the front panel sensor assembly connector by unscrewing the three screws holding it in place.
• Begin the process with the number one.Employ a 1.3-millimeter screw.
• Two.Use screws with a 1.0 mm diameter.
