OnePlus 9 5G Interconnect Cable Replacement

Difficulty

Moderate

Steps

Time Required

35 minutes - 1 hour

Introduction

This is a prerequisite-only guide! This guide is part of another procedure and is not meant to be used alone.

Use this guide to remove the interconnect cable in the OnePlus 9 5G.

Note: Retaining water resistance after the repair will depend on how well you reapply the adhesive, but your device will lose its IP (Ingress Protection) rating. However only the T-Mobile version of the OnePlus 9 5G offers an IP rating.

Tesa 61395 Tape

Step 1

Completely power off your phone before you begin.
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 2

Apply a suction handle to the rear glass, as close to the bottom edge as possible.
If your rear glass is badly cracked, covering it with a layer of clear packing tape may allow the suction handle to adhere. Alternatively, very strong tape may be used instead of the suction handle. If all else fails, you can superglue the suction handle to the broken rear glass.
Pull up on the suction handle with strong, steady force to create a gap between the glass and the frame.
If you have trouble creating a gap, apply more heat to further soften the adhesive.
Insert an opening pick into the gap.

Step 3

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 4

Insert a second opening pick underneath the bottom edge of the rear glass.
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 5

If the adhesive becomes hard to cut, it has most likely cooled down. Use your iOpener to reheat it.
Insert a third opening pick underneath the bottom left corner of the rear glass.
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 6

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 7

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

Step 8

Remove the rear glass.
If the rear glass is still stuck to the frame, slide an opening pick around the entire perimeter until the rear glass separates completely.
During reassembly secure the rear glass with pre-cut adhesive or double-sided adhesive tape. After installing the rear glass, 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 9

Use a pair of tweezers to carefully peel the bottom right corner of the charging coil tape off of the daughterboard cover.

Step 10

Use a pair of tweezers to carefully peel the bottom left corner of the charging coil tape off of the loudspeaker.

Step 11

The flash assembly is held in place by mild adhesive and covers a motherboard cover screw.
Carefully slide an opening pick underneath the bottom edge of the flash assembly.
Use your opening pick to pry up the flash assembly.
Don't try to remove the flash assembly all the way during this procedure. Its cable is adhered to the backside of the motherboard cover.

Step 12

Use a Phillips screwdriver to remove the ten 3.8 mm-long screws securing the motherboard cover.
One of the motherboard cover screws is covered by a white water ingress sticker. To unfasten the screw you can puncture the sticker with your screwdriver.

Step 13

The motherboard cover is further held in place by tight plastic clips.
Insert a spudger underneath the bottom right edge of the motherboard cover.
Pry upwards to loosen the motherboard cover and create a gap.

Step 14

Insert an opening pick underneath the bottom right edge of the motherboard cover.
Slide the opening pick up along the right edge of the motherboard cover.
Twist the opening pick to release the plastic clips and pry up the motherboard cover.

Step 15

Use a pair of tweezers or your fingers to remove the motherboard cover.
The charging coil is attached to the motherboard cover and will lift up at the same time.

Step 16

Use a spudger to disconnect the battery cable by prying the connector straight up from its socket on the bottom left corner of the motherboard.
To re-attach press connectors like this one, carefully align and press down on one side until it clicks into place, then repeat on the other side. Do not press down on the middle. If the connector is misaligned, the pins can bend and cause permanent damage.

Step 17

Use a Phillips screwdriver to remove the five 3.8 mm-long screws securing the daugtherboard cover.
One of the daughterboard cover screws is covered by a white water ingress sticker. To unfasten the screw you can puncture the sticker with your screwdriver.

Step 18

Insert the point of a spudger underneath the top right edge of the daughterboard cover.
Pry upwards to loosen the daughterboard cover.

Step 19

Use a pair of tweezers or your fingers to remove the daughterboard cover.

Step 20

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

Step 21

Slide one arm of a pair of tweezers underneath the metal bracket covering the interconnect cable.
Use your tweezers to lift and unhinge the metal bracket.
Remove the metal bracket.
