• Should the iPhone's surface prove excessively slick, preventing the Anti-Clamp from maintaining a firm grip, applying adhesive tape can provide a more textured interface.

• To disengage, draw the blue handle in a forward direction to secure the arms.
• Rotate the handle a full rotation of 360 degrees, or until you observe the cups beginning to expand.
• Confirm that the suction cups maintain their parallel positioning. Should they exhibit signs of displacement, gently release the suction cups and reposition the arms.

• Apply heat to aniOpenerand guide it between the iPhone’s side supports of the Anti-Clamp; alternatively, a hair dryer, heat gun, or hot plate can be utilized, however, exercise caution as excessive temperatures may compromise the display and/or internal battery.
• Position theiOpenerin a folded position, resting against the lower edge of the iPhone’s frame.
• Allow a sixty-second interval to permit the adhesive to soften and create a separation.
• Carefully slide an opening tool into the newly formed space beneath the display and the surrounding plastic frame, ensuring it does not contact the screen’s surface.
• Should the Anti-Clamp not generate a large enough separation, increase the heat applied to the area and rotate the handle by ninety degrees.
• Avoid incremental rotations exceeding ninety degrees, and pause for sixty seconds between adjustments, allowing the Anti-Clamp and time to facilitate the separation.
• Omit the subsequent three steps.

• Applying warmth to the iPhone's bottom edge facilitates separation by reducing the adhesive's hold on the display assembly.
• Employing a hairdryer, heat gun, or utilizing an iOpeneris recommended; direct heat to the lower edge for approximately one minute to reduce the adhesive's bonding strength.

• When employing a solitary suction handle, position it against the lower perimeter of the device's display, ensuring you do not contact the rounded glass section.

• Apply steady, consistent upward force to the suction cup to generate a small separation between the front panel assembly and the rear casing.
• Carefully slide an opening tool into the space formed beneath the display screen and the surrounding plastic trim, ensuring it does not contact the screen's surface.
• The display is secured by a robust, waterproof adhesive; overcoming this seal requires considerable effort. Should you encounter difficulty in establishing this initial separation, apply additional heat and gently oscillate the screen in an upward and downward motion to reduce the adhesive's strength until a sufficient gap is achieved for tool insertion.

• Employ the opening pick to maneuver along the lower-left periphery of the iPhone, progressing upwards along the left side, effectively separating the adhesive securing the display assembly.
• Exercise caution and limit pick insertion depth to a maximum of 3 millimeters to prevent potential harm to delicate internal components.

A fragile wire runs along the device's right side; avoid inserting your tool in this area to prevent potential cable harm.

• To proceed with separating the adhesive, re-position your opening tool at the lower boundary of the iPhone's display and advance it upwards along the right-hand side.
• Exercise caution to avoid inserting the tool beyond a depth of 3 millimeters, as doing so carries a risk of harm to the delicate display cable connections.

• Adhesive and retaining clips together fasten the display's uppermost boundary.
  Carefully exert a slight downward force on the display's right side, moving it toward the Lightning connector.
• Position a specialized opening tool within the upper-rightmost section of the device's casing.

• As necessary, maintain downward pressure on the display, directing it towards the Lightning port, to create a sufficient separation for tool insertion.
  Employ the pick to move along the upper left edge, severing any residual adhesive that is holding the display in place.
  Exercise caution to prevent the pick from penetrating beyond a depth of 3 millimeters, to avoid potential harm to the front panel sensor array.

• To detach the suction cup from the front panel, grasp and exert force on the small protrusion located on its surface.

1. To access the internal components, initiate the display opening process by pivoting the screen upwards from the left edge, mimicking the action of opening a book's cover.
   Refrain from completely disconnecting the display at this stage, because multiple delicate ribbon cables remain attached to the iPhone's main circuit board.
