To replace the iPhone Back Glass Adhesive, first we need to remove all remaining adhesive, clean the back glass and frame; then adjust the direction of the new adhesive and expose it, carefully apply it along the edge of the iPhone.

Essential mobile phone repair tools:

• Tweezers
• Cleaning cloth
• Pry bar
• Hot Air Gun
• Screwdriver
• Replace adhesive
• Screen vise clamp

Before proceeding, we must ensure the following 2 safety precautions:

1. Discharge the battery to less than 25% to reduce the risk of fire in the event of accidental battery damage.
2. Power off the iPhone before starting disassembly.

Remove remaining adhesive:

1. Use tweezers to peel off the remaining adhesive on the frame. If the adhesive is stubborn, use a hair dryer or heat gun to heat it.
2. Use a pry bar to press and roll the adhesive off the frame.
3. Use blunt-tipped tweezers or your fingers to remove loose adhesive.

Clean the back glass frame:

1. Place a few drops of high-concentration isopropyl alcohol on a microfiber cloth and wipe around the perimeter of the back glass and frame to prepare for applying new adhesive.
2. Make sure there is no residue, which can compromise the iPhone's seal, and be sure to clean the back glass and frame thoroughly.

Apply the replacement adhesive:

1. Place the replacement adhesive on the frame with the larger blue liner on the bottom surface and the pull tab on the bottom right corner.
2. Use features such as the camera cutout and groove to properly align the adhesive.
3. Peel off and use only the blue liner pull tab to expose the bottom edge of the adhesive.
4. Align and place the bottom edge of the adhesive into the groove in the frame, making sure to align with the spring contacts.
5. Apply the adhesive along the sides, peeling the blue liner as you go, making sure it is straight.
6. Align the top edge groove with the frame, lower the top edge of the adhesive, and completely peel off the blue liner.
7. Use a Spudger to press the adhesive around the perimeter, avoiding the spring contacts.
8. Use the pull tab on the top right corner to remove the pink adhesive backing.

Reattach components:

1. Support the rear glass along the right edge of the iPhone.
2. Use the flat end of a spudger or your finger to reattach the charging coil.
3. Use a screwdriver to install the screws that secure the charging coil connector cover to the logic board slot or hook.
4. Reattach the battery and use a Screwdriver to install the screws that secure the battery connector cover.
5. Open the iPhone to test functionality before sealing; power off, then complete the repair.

Seal the rear glass:

1. Remove liners from top, left, and bottom edges; wait for right edge liner removal until last step.
2. Elevate rear glass to access final liner along right edge; peel and remove without catching cables or clips.
3. Straighten any bent clips on rear glass gently with fingers.
4. Align rear glass over frame, engage top clips first, then press around perimeter to engage remaining clips.
5. Apply heat to edges using hair dryer or heat gun until hot to touch; press firmly around perimeter to bond adhesive.
6. Use screen vise clamps if available for stronger bond; alternatively, use heavy objects overnight for compression if clamps are unavailable.

Use a screwdriver to install two screws to the bottom edge of the iPhone.
