Huawei P30 lite - Speaker 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.

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.

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.

3. Then connect the contact.

1. Before you finally close the device again, you should test it.
2. Start the smartphone and open the "HiCare" app.
3. Execute the Smart Diagnostics function. Some functions are now tested automatically.
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.
