Huawei P30 lite - Screen replacement

1. Switch off your Huawei P30 lite by pressing the power button.
2. Confirm the switching off and wait until the device has shut down.

In this step, the heavily glued back cover of the Huawei P30 lite must be removed.

1. First heat the frame of the unit with hot air. A temperature of 60-80 degrees is suitable for this. By heating the frame, the glue can be removed more easily.
2. Place a suction cup in the lower part of the backcover and pull on it while pushing your opening tool into the resulting gap.

Instead of a suction cup you can also use an iSlack. This tool works like pliers and has suction cups on both sides.To get into the narrow gap first, we recommend the opening tool iFlex, which is made of thin, strong metal. Once it is inserted, it is advisable to change to a plastic tool such as the iPlastix. This is not as easy to insert into the gap, as it is somewhat more flexible. However, it is very suitable for loosening the back cover, as it does not scratch the frame of the device.

1. Guide a plastic plectrum into the already loosened part. This prevents the glue from reattaching.
2. Work your way along the entire edge of the back cover. Keep heating up from time to time to make it easier to remove.
3. Be careful and patient during this step to avoid breaking anything. The backcover is made of glass and can break easily.

Be careful not to insert your tool too far into the device. On the left side are the cameras and on the right side is the flex cable of the fingerprint sensor.

1. The motherboard and its connectors are protected with a cover.
2. Remove the screws that fix the cover. Pay attention to the different screw lengths. The black screws are slightly longer than the silver ones.

In order not to confuse the different screws we recommend an iDoc magnetic mat.

1. On one of the screws there is a small white moisture indicator. You can easily remove it and put it back on during the assembly.
2. Lever the cover slightly upwards at various points to release it.

The cover cannot be removed from the device yet, because the connector of the fingerprint sensor has to be disconnected first.

• Battery Connector

1. Above the battery connector there is still a small metal cover.
2. Remove the screw and take the cover out of the device with tweezers.
3. Now the battery connector is exposed and can be removed with a plastic spudger.

The battery contact should always be loosened first to prevent further current flow in the device. This prevents short circuits during repairs.

• Fingerprint Connector

1. Now disconnect the contact of the fingerprint sensor from the motherboard.
2. Now you can put the backcover aside and also remove the cover of the board from the device.

1. Now remove the battery from the device.
2. To do this, remove the orange adhesive tabs from the battery. Now pull the tabs evenly to remove the battery from the device.

1. Make sure not to bend the battery during this step!
2. Once the battery is detached, you can remove the foil with the pull tabs from the device to insert it into your new display later.

Our original Huawei replacement displays already have a new battery installed, in this case you can skip taking over the pull tabs. Nevertheless we recommend to remove the battery from the old display in order to recycle the two components properly.

• Antenna Connector

1. Disconnect the connectors of the two flex cables from the motherboard.
2. Then disconnect the connector of the antenna cable. Move a pair of tweezers under the connector and release the connection with a slight twisting motion.
3. Then remove the SIM card holder from the device.
4. Bend all cables a little to the side to avoid getting stuck with the mainboard.
5. Lift the board upwards at different places and take it out of the device.

The black foil serves the heat distribution in the device and can be taken out of the device together with the mainboard.

• Antenna Connector

1. Disconnect the contact of the flexible cable and the antenna plug from the USB-C board.
2. Then lever the board out of the device with a plastic tool.

On this board you will find the charging socket and the headphone jack.

1. Pull the antenna cable out of its guide on the edge of the frame.
2. Then remove the slightly glued flex cable connecting the main and USB-C board.

You can heat the cable a little bit to make it easier to remove.

1. Now take your new display and compare it with the old one.
2. It may be that small parts of your old display still need to be transferred to the new one.
3. Then remove all protective films over adhesive surfaces and various openings.

We don't use a new display in this manual because ours still worked perfectly. But the disassembly works the same way with a new display. If your new display already has a battery installed, you can skip the step of inserting the battery.

1. Now glue the flexible cable back into the device.
2. Then lead the antenna cable back into its guide in the frame.

3. Then reconnect the two connectors of the flex cables and the contact of the antenna cable.

1. If your replacement display does not include a new battery, first place the adhesive foil with the pull tabs back into the device.
2. Then reinsert the battery and stick the tabs back in place.
3. Make sure that the battery has enough space on all sides of the device.

1. To reglue the backcover, you can either use the old glue or a new adhesive frame. In either case, make sure that the device is no longer fully protected against liquids and dust.
2. Check the old glue and straighten it if it's unevenly distributed in some places.
3. If you want to use a new adhesive frame, remove the old adhesive from the back cover and frame of the unit.
4. You can peel off the glue with tweezers and scrape off some residue with a plastic tool. You can also use rubbing alcohol and a lint-free cloth to remove glue residue.
5. Then check the position of the glue, pull off the first protective film from the adhesive frame and position it on the back cover. Make sure that it does not protrude anywhere.
6. The two smaller adhesive surfaces must also be positioned on the back cover.
7. Run along the adhesive and press it down.
8. Then you can remove the protective foils over the adhesive surfaces.

• Fingerprint Connector

1. To reconnect the fingerprint sensor, you must put the plastic cover of the main board back into the device first.
2. Now place the backcover next to the device and position the contact over the connector on the mainboard. Make sure that the flex cable is not twisted.
3. Then connect the contact.

4. In the menu item "manual" you can now test other functions independently. Test the touch screen, microphone, speaker and other functions.
5. If something does not work as expected, check the corresponding component for possible damage or if it is connected correctly.
6. If everything is ok, you can finally close the device.

1. Now position the backcover on the device and press it down.
2. Heat the edge of the device again with hot air and weigh down the backcover with a few books to make the glue stick even better.
