(New) iPhone 15 Back Glass Installation (for Logic Board)

Step 1

Remove the back glass adhesive

⌕

• Be careful not to damage any of the spring contacts as you clean the frame.
• This is a good point to test your repair before sealing up your phone. Connect the battery and back glass, power on your phone, and make sure it works as expected. Power it back down, disconnect the battery and back glass, and continue reassembly.
• The adhesive remaining on your phone is difficult to remove and leaves residue. If you have trouble removing the adhesive, apply some heat using a hair dryer or heat gun.
• Use the pointed end of a spudger to press and roll the adhesive until you can grip it with a pair of tweezers.
• Use the tweezers to pull the adhesive off of the phone.

Step 2

Repair step

⌕

• Any leftover residue will compromise your iPhone's seal. Be sure to clean the frame thoroughly.
• Wrap a microfiber or lint-free cloth around the pointed end of a spudger and apply a few drops of high-concentration (greater than 90%) isopropyl alcohol to the cloth.
• Wipe in one direction along the perimeter of the frame to clean the adhesive residue.
• Wait a few minutes before proceeding to make sure any excess alcohol has evaporated.

Step 3

Orient the adhesive

⌕

• Lay the adhesive next to the phone and use features like cutouts for spring contacts and the rear camera to make sure the adhesive is oriented correctly.
• Your adhesive may look slightly different.

Step 4

Apply the adhesive

⌕

• Once the adhesive is pressed into place, you can't reposition it—you'll have to remove it and start over with new adhesive.
• Use the pull tab to begin peeling the back liner off the adhesive starting from the bottom, but don't remove the liner all the way.
• Hold the liner out of the way and align the adhesive with the bottom edge of the iPhone.
• Lay the bottom edge of the adhesive into its recess in the frame, making sure the iPhone's spring contacts are aligned with their cutouts in the liner.

Step 5

Repair step

⌕

• When the adhesive is aligned, use the flat end of a spudger or your finger to press it down firmly along the bottom edge.

Step 6

Repair step

⌕

• Continue peeling the back liner off of the adhesive while pressing the adhesive into place along the edges of the iPhone's frame.
• If you correctly aligned the lower edge of the adhesive, the side and top edges will fall perfectly into place. If the adhesive is misaligned, remove it and start over with new adhesive.
• If your adhesive is misaligned and you don't have another set handy, it's okay to temporarily put your iPhone back together and use it normally without any adhesive, but keep in mind that your iPhone's water resistance will be compromised until you install new adhesive.

Step 7

Press the adhesive into place

⌕

• Make sure the liner is aligned properly by checking that all spring contacts and the rear camera are in their cutouts. If they aren't, remove the adhesive and start over with a new sheet.
• Use the flat end of a spudger to press the adhesive into place around the perimeter of the frame.
• Be careful not to touch the spring contacts sticking through the pink liner.

Step 8

Remove the top liner

⌕

• Remove the top adhesive liner.
• Depending on your adhesive, your liner might be split into multiple parts or be a single piece.

Step 9

Prop up the back glass

⌕

• Prop up the back glass along the right edge of the iPhone, using a box or similar sturdy object to support the screen.
• Use the flat end of a spudger or your finger to connect the wireless charging coil press connector, then the battery press connector.

Step 10

Place the middle connector cover

⌕

• Place the middle connector cover over the wireless charging coil press connector so it slightly overhangs the slot on the logic board for the bottom clip.

Step 11

Repair step

⌕

• Use your finger to press the cover down on the logic board.
• While pressing it down, slide the cover upward so both metal clips slot into their spots in the logic board.

Step 12

Place the lower connector cover

⌕

• Use tweezers to hook the top of the lower connector cover into its slot on the logic board.
• Lay the lower connector cover over the press connectors.

Step 13

Install the cover screws

⌕

• Use a tri-point Y000 screwdriver to install the 0.9 mm‑long screw securing the middle connector cover.
• Use a tri-point Y000 screwdriver to install the two 1.3 mm‑long screws securing the lower connector cover.

Step 14

Remove the final adhesive liners

⌕

• Use tweezers or your fingers to separate the pull tabs at the bottom of the frame, near the charging port.

Step 15

Repair step

⌕

• Remove the narrow liner covering the adhesive along the left and top edges of the frame.

Step 16

Repair step

⌕

• Hold the back glass over the phone without letting it touch the adhesive, so you can access the remaining liners along the right edge of the phone.
• Use a pair of tweezers or your fingers to remove the remaing liners along the right edge of the phone.

Step 17

Install the back glass

⌕

• Lay the back glass straight down onto the frame and press until the clips engage.
• Press around the perimeter of the back glass to engage all the clips.

Step 18

Heat the back glass

⌕

• To help the adhesive bond, apply heat to the edges of the back glass using an iOpener, hair dryer, or heat gun until it's hot to the touch.
• Firmly press around the perimeter of the back glass.
