DIY OnePlus 9 Teardown | LCD Screen Repair Guide

Before Starting, we need to have the right tools to proceed with the teardown, which you can find in the description.

First, turn off the phone and take out the SIM tray, followed by the back cover removal. To remove the back cover, it needs to hit gently around the back of the edges until the pastel adhesive becomes soft.

For this, we are using a heating pad. Place the background side on the pad and, select the mobile phone heating option, and leave it till the heating completes.

Alternatively, you can use a heat gun or hair dryer. Once the heating has been completed, use a suction cup to create an opening between the frame and the rear cover.

Next, insert a plastic card pry tool or something similar to cut the adhesive around the back cover.

Take out the back cover, and as visible, there is water all around the phone.

Next, take out the main board frame by undoing the screws. Undo nine screws and lift the protector cover using a pry tool. Just a quick note there is a hidden screw under the plate near the camera module. Just make sure to take it out.

Next, take out the shield and disconnect the flasher plug.

Next, lift and take out the wireless coil with the main board frame using a pry tool.

Next, from the right-hand side, disconnect the battery plug.

In oneplus 9, there are three rear cameras, and the white camera and depth camera come as a two-in-one unit. However, the dev camera can take a note by applying a little pressure on the top.

Next, disconnect and take out the white camera and the front camera on the board.

Next, loosen two more screws that are secure in the logic board.

Next, on the left-hand side, take off the shield protecting the lcd connector plug.

Next, unplug the top end on the charge port flex main flex followed by the lcd flex cable, and next, undo three antennas on the board and make sure to loosen the adhesive under the earpiece.

Next, move aside the antennas and gently take out the logic board as you can see, the water has soaked into the logic board.

Next, move to the bottom section and undo seven screws to take out the PCB cover.

Next, take out the shield on the main flex cable and disconnect the bottom and the main ribbon before pulling it out.

Next, disconnect the touch ID flex connector and two antennas on the bottom PCB.and next, undo one more screw and pull out the bottom PCB, which includes the sim card tray.
Next, gently pull out the charge board flex cable and the speaker module from the body.

Next, apply the heat, take off the taptic engine, and touch the ID camera flex.

Next, move back to the top and apply the heat to take out the speaker and sensor flex cable. Be gentle and slowly pull out the parts.

Next, to take off the battery, loosen the adhesive on the sides and then pull them by the red tap on both sides.

Finally, disconnect the tail end of the lcd connector plug first, move the battery protective tape to the right-hand side, and peel the lcd flex cable.

Be careful. There is a sticky strip on the edge of the bottom PCB. Move aside and pull out the cable by applying a little heat.
