• To prevent electrical shock or damage, ensure the iPhone is completely de-energized prior to starting the repair process.
• Using a tool compatible with 3.4 mm pentalobe fasteners, detach the two screws located along the device's lower border.
• Because removing the display panel will damage the iPhone's water resistance, ensure you have new seals available for installation before continuing, or exercise extreme caution to prevent liquid ingress if you reinstall the display without replacement.

• To avoid potential damage to your device, ensure the opening pick does not extend beyond a safe depth; use this step to create a reference mark on the pick, limiting its insertion.
• Determine the dimension using a suitable measuring tool.Three millimeters.Using a permanent marker, indicate the opening point on the pick.
• Alternative corner markings, using the same measurement tools, can be applied to the remaining corners of the pick.
• Securely affix a coin to the tip of a pick using adhesive tape.Three millimeters.Beginning at the very end.

To simplify the opening process, the following three steps utilize the Anti-Clamp tool; if you do not have this tool, proceed to the instructions three steps further down.

Refer to the included guide for detailed procedures regarding Anti-Clamp operation.

• To release the Anti-Clamp’s arms, move the blue handle in a rearward direction.
• Position the arms so they extend across the iPhone's left or right side.
• Affix two suction cups to the iPhone's front and back surfaces, placing them close to the lower edge, directly over the home button.
• Apply vacuum by pressing the cups firmly against the surface needing treatment.
• To improve the Anti-Clamp's grip if the iPhone's exterior feels excessively smooth, apply adhesive tape to the device's surface.

• Moving the blue handle in a forward direction will engage the locking mechanism for the arms.
• Rotate the handle in a direction that tightens it.Rotate fully around its axis.Continue the process, observing for signs of cup expansion.
• Maintain parallel positioning of the suction cups; should misalignment occur, gently release the suction cups' grip and reposition the arms.

• Apply heat to the component using a heat gun.Utilize the iOpener device.Carefully guide the string through the arm openings.Prevent clamping..
• To soften adhesives, apply warmth from a hair dryer, heat gun, or hot plate; however, exercise caution as excessive heat may harm the display panel and/or the internal battery.
• Carefully bend theUse the iOpener to gently warm the adhesive securing the display assembly to the device's midframe, maintaining a consistent temperature and avoiding excessive heat.Position the component along the lower edge of the iPhone.

Employing a suction cup, proceed with the following three steps to detach the display assembly.

• Applying heat to the phone's bottom perimeter with a heat gun or hairdryer will loosen the adhesive that holds the display in place, facilitating separation.
• Apply heat with a hairdryer or similar device to gently warm the component, ensuring the temperature does not exceed 150°F (65°C).Use the iOpener.To loosen the adhesive securing the lower portion, hold a heat source against that edge for roughly 90 seconds.

Using a suction cup, secure it to the front panel's bottom portion, positioned directly over the home button.

To ensure a proper seal between the suction cup and the front glass, avoid positioning the cup so that it covers the home button.

• Apply steady, even force to lift the suction cup, generating a small separation between the display assembly and the device’s surrounding frame.
• Using a specialized opening tool, carefully create a small separation between the surfaces.
• Due to the robust nature of the watertight adhesive securing the screen, substantial force is required to initially separate it. Should you encounter difficulty, apply additional heat and use a gentle rocking motion to soften the adhesive, gradually increasing the gap until it's sufficient for tool insertion.

• Beginning at the phone's bottom edge, insert the opening pick between the display and the chassis, carefully working it upwards along the left side, progressing towards the volume buttons and silent switch to release the adhesive securing the display.
• Position yourself close to the upper left edge of the screen.
• Avoid separating the display's upper border from the back cover by force; it is secured with plastic clips susceptible to damage.

Avoid inserting any tools along the right side of the iPhone, as the sensitive internal wiring in that area is susceptible to damage.

• Using your tool, begin at the lower-right edge of the iPhone and move it along the perimeter, releasing the adhesive bond by sliding it along the corner and up the right side.
• Ensure the pick's insertion depth remains limited toThree millimeters.Exercise caution to prevent harm to the display cables.

• Using a suction cup, apply upward force to the display's lower border to detach it.
• Ensure the display’s elevation remains below the specified maximum of.Set the temperature dial to 150 degrees.Careless handling may damage the display's ribbon cables, potentially causing them to stretch or rip.

• For users unfamiliar with iPhone battery adhesive strip removal, consult the video provided in the subsequent step to ensure proper technique.
• To ensure proper removal, maintain the strips' flatness and avoid creases, as folds can cause them to adhere and tear rather than separate easily.
• Gently detach a battery adhesive strip, moving it downwards along the iPhone's chassis.
• Apply consistent, even force to the strip, ensuring it remains taut as it disengages from the space between the battery and the rear case; to optimize the process, limit the pulling angle to 60 degrees or less.
• Expect the strip to extend significantly, potentially several times its initial measurement. To maintain tension and progress, reposition your grip closer to the battery as needed while continuing to pull.

Perform the identical procedure on the remaining strip.
To prevent the battery from being ejected forcefully during separation, maintain consistent pressure on it while detaching the second strip.
Having completely detached both adhesive strips, proceed directly to the subsequent instruction.
Should the adhesive strips securing the battery become detached and inaccessible, proceed to the subsequent instruction.

• Apply a small amount of adhesive to the rear case where the battery is adhered, in the event that the original adhesive strips have detached.Use rubbing alcohol, which is isopropyl alcohol.Ensure at least 90% of the area located beneath the battery is cleared of obstructions, paying close attention to any adhered strip(s).
• Allow approximately one minute to elapse before carefully raising the battery.
  To prevent damage to the volume control cable located beneath, avoid using the spudger in the space positioned between the volume down (-) button and the battery's top edge.
• Applying force to the logic board can result in device damage.
  To prevent damage, avoid using excessive force when releasing the battery. Should the adhesive still resist separation, add additional alcohol droplets to soften it. Ensure the pry tool does not create any dents or holes in the battery's casing during the removal process.
• To free a battery adhered to the rear cover, apply heat using an iOpener or hair dryer to the area immediately behind the battery; the surface should reach a temperature just above comfortable touch.
  Exposure to excessive heat poses a risk of battery ignition in the iPhone.
• To release the battery from the back cover, use dental floss or, for greater leverage, a 0.009-inch E string from a 12-string guitar set. Insert the floss or string between the battery and the rear case at the top corners, join the ends, secure them around a folded piece of cloth, and then apply consistent tension to separate the components.

• Disconnecting the power source, carefully take out the battery located within the rear case.
• Carefully slide the protective plastic covering off the new battery, ensuring you don't snag or damage the ribbon cable during removal.
• To prevent damage, ensure any residual alcohol solution is completely removed by wiping with a clean cloth or by permitting it to evaporate fully prior to battery installation.
• To guarantee correct positioning within its designated space, briefly plug the battery connector back into the logic board socket prior to securing the new battery.
• Secure the battery in place, then sever its electrical connection before proceeding with the remaining assembly steps.
