iPhone 6s Plus Rear Case Replacement

• Ensure the battery's charge level is less than 25%; a fully charged lithium-ion battery presents a fire hazard and potential explosion risk if it sustains damage.
• Deactivate your iPhone by powering it down to prevent any electrical issues during the disassembly process.
• Begin by unscrewing the pair of 3.4 mm Pentalobe screws located on both sides of the Lightning connector.

• Should you choose not to utilize the Anti-Clamp, proceed to skip ahead three steps to access an alternative approach.
• Detailed instructions regarding the Anti-Clamp's operation can be found within this separate guide.
• To release the Anti-Clamp's gripping arms, retract the blue handle towards the rear.
• Carefully position the arms across either the left or right side of your iPhone’s frame.
• Place the suction cups close to the lower edge of the iPhone, situated directly above the home button; one cup should be on the front surface, and the other on the rear.
• Apply pressure by compressing the cups together to establish a secure suction bond to the intended area.
• In cases where the iPhone’s surface exhibits excessive slipperiness, hindering the Anti-Clamp’s ability to maintain grip, applying adhesive tape can provide a more textured surface.

• Rotate the handle a full 360 degrees, or continue turning until the suction cups begin to expand.
• Maintain the precise alignment of the suction cups; should they become misaligned, slightly release the suction cups and readjust the arms.

• Introduce gentle warmth to the iPhone's bottom border with either an iOpener or a hair dryer, maintaining the heat for approximately one minute.
• The application of heat serves to reduce the stiffness of the adhesive that holds the display in place, thereby simplifying the opening process.

• Should you wish to substitute the existing adhesive, ensure a fresh supply of adhesive strips is accessible prior to proceeding. The repair can be successfully finished without adhesive replacement, and operational performance is unlikely to be affected.

• To separate the front panel from the rear case, exert steady, consistent upward force on the suction cup, ensuring a minimal space forms.

• Utilize the spudger, rotating it to incrementally increase the separation between the front panel assembly and the rear enclosure.

• Employing the flat end of the spudger, carefully position it beneath the rightmost border of the display.spudgerTo separate the display from the device's frame, gently maneuver the spudger beneath the right edge.
• Using the spudger, proceed to slidespudgeralong the right-hand side of the device.

• Employ aplastic opening toolto maintain pressure on the rear enclosure as you lift the suction cup, facilitating the phone's opening.
• Refrain from detaching the display assembly entirely,as doing so risks harming the delicate data cables situated close to the upper portion of the iPhone.

• Carefully lift the display assembly by its edges, pivoting it open like a hinge, utilizing the clips located at the top of the front panel.
• Position the opened display at approximately a 90-degree angle and secure it in a propped position to facilitate work on the device.
• Avoid exceeding a 90-degree opening angle, as the display remains tethered to the phone's upper section via the display cable, digitizer cable, and front camera cable, which are susceptible to damage.
• Employ a rubber band to maintain the display's stability during the repair process, minimizing stress on the delicate display cables.
• As an alternative, an unopened, sealed beverage container can be used to provide support for the display if a rubber band is unavailable.

• To detach the battery connector bracket from the logic board, first, eliminate two Phillips screws that hold it in place; these screws have differing lengths.
