• To mitigate additional damage and potential injury while repairing a rear glass fracture on your iPhone, secure the broken area with adhesive tape.
  Completely cover the iPhone’s rear glass surface by applying successive layers of transparent packing tape, ensuring substantial overlap between each strip.
• Protect your vision by utilizing safety eyewear, as shards of glass may become dislodged during the repair process.
• Should the suction cup fail to maintain adhesion during subsequent procedures, create a handle by folding a durable tape, like duct tape, and employ it to elevate the rear glass.
• As a last resort, secure the suction cup directly to the rear glass using superglue to facilitate lifting.

• Apply warmth to the lower perimeter of the iPhone’s casing utilizing a hair dryer or heat gun, ensuring the rear glass panel reaches a temperature just beyond comfortable touch.
  Avoid prolonged, localized heat application with the heat gun to prevent damage.

• Secure a suction handle to the lower border of the back glass, ensuring you maintain clearance from its perimeter.
• Maintain steady, consistent upward force on the suction cup to generate a minimal separation between the rear glass and the device's frame.
• Introduce an opening tool into the newly formed space.
• Due to the robust nature of the adhesive securing the rear glass, substantial force may be needed to initially separate it; if separation proves difficult, apply additional heat and gently oscillate the rear glass to reduce adhesive strength until a sufficient gap is achieved for opening tool insertion.

To facilitate separation, apply heat to the left side of the iPhone's enclosure, raising the temperature of the rear glass to a point just beyond comfortable touch.

• Employ the opening pick to maneuver along the lower-left perimeter of the iPhone's rear glass, then continue upward along the left edge, severing the adhesive securing the glass.
• Ensure the pick's insertion depth remains limited to a maximum of 3 millimeters to prevent potential harm to the device's internal elements.Exceeding this 3 mm depth threshold carries a risk of compromising delicate internal components.Carefully manage the pick's position to avoid unintended contact with the iPhone's internal structure.

To initiate separation, apply heat to the right-hand perimeter of the iPhone, specifically the area containing the power button, until the temperature of the rear glass reaches a point where it becomes noticeably uncomfortable to the touch.

• Reposition the opening tool near the lower boundary of the iPhone’s enclosure.
• Advance the tool upwards along the right-hand side to further release the adhesive sealant.

• Position a prying tool beneath the upper-left corner of the device's casing.
• Maneuver the tool along the top-left corner, extending it to the midpoint of the top edge.Ensure the tool's insertion depth remains limited to a maximum of 3 millimeters to prevent potential harm or distortion of the camera module.Refrain from completely detaching the rear glass panel at this stage, because a delicate ribbon cable provides the electrical connection between the glass and the iPhone's main circuit board.
• Premature separation could risk damaging this sensitive cable.

• Detach the suction handle from the rear glass assembly.
• Carefully separate the iPhone's rear glass by pivoting it upwards from the left edge, mimicking the action of opening a book's cover.
• Exercise caution to prevent damage to the brief charging coil flex cable.
• Support the rear glass in an upright position during the repair process; alternatively, the suction handle can serve this purpose if a dedicated support is unavailable.

• Employ a Y000 screwdriver to detach the two screws, each measuring 1.3 mm in length, which fasten the battery connector cover.Carefully monitor the location of each screw during the repair process, ensuring correct placement during reassembly to prevent potential damage to your iPhone.To prevent component damage, meticulously document the origin of every screw encountered during disassembly.
• Prior to permanently securing the display, it's advisable to activate your iPhone and verify all functionalities at this stage of the repair.
• Completely deactivate your iPhone before proceeding with subsequent repair steps following the functional verification.

• Using tweezers, secure the battery connector cover and advance it in a direction parallel to the 'A15' marking to release the upper retaining latch.
• Detach the battery connector cover from the device.

• Employ the tapered end of a spudger to release the battery connector, lifting it vertically from its receptacle.Exercise caution to avoid harming the black silicone sealant found around this and other board interfaces, as it safeguards against water and dust penetration.To preclude unintended power delivery to the device during the repair process, slightly angle the connector away from the main circuit board.
• The battery cable's disconnection requires a direct upward force applied with the spudger's pointed tip.
• Maintaining the integrity of the silicone seals is crucial for preserving the device's environmental protection capabilities.

• Employ a Y000 screwdriver for the task of detaching the charging coil connector cover.The fastener in question is a 1.0 mm screw.This screw is the sole means of securing the cover.Carefully remove the screw using the appropriate screwdriver.The charging coil connector cover is held in place by this single, small screw.

• Employing tweezers, detach the protective cover that secures the charging coil connector.

• Employ the tapered tip of a spudger to release the charging coil cable's connector, lifting it vertically away from its receptacle.Carefully separate the charging coil cable connector from its socket utilizing the pointed spudger tip, ensuring a straight upward motion.To detach the charging coil cable, apply the spudger's pointed end and elevate the connector directly out of its corresponding socket.

• If a rear glass adhesive replacement is desired, momentarily halt the reassembly process at this juncture.
• The rear glass assembly must be removed as indicated in this step.

• A small, black pull-tab is integrated into the terminal end of each adhesive strip, initially secured to the battery's surface.
• The subsequent actions require gently extending each pull-tab, which will gradually release the underlying adhesive, enabling battery separation; these adhesives function similarly to 'command strips', losing adhesion when stretched.
• Should the adhesive strips tear during the release process, proceed with the following troubleshooting guidance for alternative removal methods.

• Maintain consistent tension on the adhesive strip during extraction, allowing ample time for it to extend and release from beneath the battery, avoiding abrupt force.
• Securely hold the iPhone's frame while performing this action, ensuring that you do not apply pressure to the battery itself.
• Maintain a smooth, wrinkle-free profile for the adhesive strip, distributing pulling force uniformly across its entire length to prevent localized stress.
• Should the adhesive strip fragment during removal, attempt to recover the detached pieces using your fingers or blunt tweezers, and continue the extraction process – avoid prying beneath the battery.
• In the event that fragments of the adhesive strip become lodged beneath the battery and are inaccessible, proceed with removing the remaining strip and follow subsequent instructions.

• Maintain the same technique as utilized for the prior strip, avoiding any downward pressure on the battery itself.
• Ensure the adhesive strip remains smooth and free of creases during the lifting process.
• Apply tension to the strip at a shallow inclination.

• Allow approximately sixty seconds for the alcohol to permeate and reduce the adhesive's bonding strength.

• Substituting a battery exhibiting physical damage or distortion presents a significant safety risk and should be avoided.
