Parts

Tesa 61395 Tape

Step 1

Insert a SIM card eject tool into the small hole in the SIM card tray, located on the upper left edge edge of the phone.
Press firmly to eject the tray.

Step 2

Remove the SIM card tray from the phone.
When reinserting the SIM card, make sure it's in the proper orientation inside the tray.
A thin rubber gasket around the SIM tray provides water and dust protection. If this gasket is damaged or missing, replace the gasket or the entire SIM tray to protect your phone's internal components.

Step 3

Prepare an iOpener and apply it to the rear glass for at least three minutes to loosen the adhesive underneath.
A hair dryer, heat gun, or hot plate may also be used, but be careful not to overheat the phone—the display and internal battery are both susceptible to heat damage.

Step 4

Due to its surface, no suction tool will hold onto the phone's rear glass. A thin slicing tool is required to create a gap between the rear glass and the midframe.
Insert an iFlex into the seam between the rear glass and the midframe at the bottom edge of the phone to create a gap. This may require some force.
Leave the iFlex in place to prevent the adhesive from resealing.

Step 5

Insert an opening pick into the gap you created with the iFlex.
Remove the iFlex.

Step 6

Slide the opening pick to the bottom right corner to slice the adhesive.
Leave the opening pick in place to prevent the adhesive from resealing.

Step 7

Insert a second opening pick at the bottom right corner of your phone.
Slide the opening pick to the bottom left corner to slice the adhesive.
Leave the opening picks in place to prevent the adhesive from resealing.

Step 8

If the adhesive becomes hard to cut, it has most likely cooled down. Use your iOpener to reheat it.
Insert a third opening pick at the bottom left corner of your phone.
Slide the opening pick along the left edge of your phone to slice the adhesive.
Leave the opening pick in the top left corner to prevent the adhesive from resealing.

Step 9

Insert a fourth opening pick underneath the top left corner of the rear glass.
Slide the opening pick along the top edge to slice the adhesive.
Leave the opening pick in the top right corner to prevent the adhesive from resealing.

Step 10

Insert a fifth opening pick underneath the top right corner.
Slide the opening pick along the right edge of the back cover to slice the remaining adhesive.

Step 11

Remove the back cover.
Secure the new back cover with pre-cut adhesive or double-sided adhesive tape. After installing the back cover, apply strong, steady pressure to your phone for several minutes to help the adhesive form a good bond—a stack of heavy books works well.

Step 12

Use a pair of tweezers to remove the metal bracket covering the flash assembly connector.

Step 13

Use the point of a spudger to disconnect the flash assembly cable by prying the connector straight up from its socket.

Step 14

Use a Phillips screwdriver to remove the nine 3.8 mm-long screws securing the motherboard cover.

Step 15

The motherboard cover is held in place by plastic clips.
Insert an opening pick underneath the bottom right edge of the motherboard cover.
Twist the opening pick sideways release the plastic clips and to pry up the motherboard cover.

Step 16

Remove the motherboard cover.

Step 17

Use a spudger to disconnect the battery cable by prying the connector straight up from its socket.

Step 18

Removing the daughterboard cover isn't mandatory to replace the battery. However, doing so reduces the risk of damaging surrounding components.
Use a Phillips screwdriver to remove the six 3.8 mm-long screws securing the daugtherboard cover.

Step 19

Insert the point of a spudger underneath the top right edge of the daughterboard cover.
Pry upwards to loosen the daughterboard cover.
Don't try to remove the daughterboard cover all the way yet. It's still adhered to the loudspeaker.

Step 20

Fold the daughterboard cover to the left like you would open the front cover of a book.
Carefully peel the black tape off of the loudspeaker.
Remove the daughterboard cover.

Step 21

Use a spudger to disconnect the interconnect and the antenna board cables by prying the connectors straight up from their socket.

Step 22

Use a spudger to disconnect the fingerprint sensor and the interconnect cables by prying the connectors straight up from their sockets.

Step 23

Use a spudger to disconnect the display cable by prying the connector straight up from its socket.

Step 24

Use a Phillips driver to remove the 2.8 mm-long screw securing the daughterboard.

Step 25

Insert the point of a spudger underneath the top edge of the daughterboard.
Pry upwards to loosen the daughterboard.
Don't try to remove the daughterboard all the way yet. There's an antenna cable on its bottom that is still connected to it.

Step 26

Use a pair of blunt nose tweezers to carefully fold the daughterboard over in direction of the battery.

Step 27

Slide a one arm of a pair of tweezers under the black antenna cable until they're snug against the metal connector.
Disconnect the upper antenna cable by prying it straight up from the daughterboard.

Step 28

Remove the daughterboard.

Conclusion

Compare your new replacement part to the original part—you may need to transfer remaining components or remove adhesive backings from the new part before you install it.

To reassemble your device, follow these instructions in reverse order.

During reassembly, apply new adhesive where it's necessary after cleaning the relevant areas with isopropyl alcohol (>90%).

Take your e-waste to an R2 or e-Stewards certified recycler.
