Problem: Huawei Mate 20 Pro won’t turn on

Hi, I’m using the Huawei Mate 20 Pro for like a month and out of nowhere I used it then locked it and pressed the power button one time to unlock it after i didnt use it for like 3 mins and it just died on me. i don’t know what to do with it now because it doesn’t turn on no matter what i do. i tried connecting it to a pc or to the original power adapter and still nothing … nothing happens. 🙁

I’m really disappointed from it cause I really like this phone. I hope you guys have some advice to me or knows how to fix the problem.. Thank you very much 🙂

Solution: If you find your Huawei Mate 20 Pro suddenly unresponsive and won’t turn on, there may be an app or software bug that causes it. If the device fail to power on after you dropped or hit it physically, skip the software troubleshooting and go directly to repair part by calling Huawei.

Try another set of charging accessories

This should be the first thing that you want to do. If you have another set of known working USB cable and adapter, use that to charge the device. The USB cable that comes with your device is consists of tiny wires that can easily break. The more wires are disconnected inside, the lower the energy that gets transferred from the adapter to the phone during charging. This can lead to the loss of fast charging capability and eventually, the cable becomes unusable.

If possible, visit your local Huawei store and charge your device using original charging cable and adapter.

Forced reboot

Temporary bugs may sometimes freeze a device giving the appearance of what you’re experiencing right now. On older devices with removable battery packs, an issue like this can be fixed easily by removing the battery. This is not possible for a Huawei Mate 20 Pro though so you can only try simulate the effects of physically disconnecting the battery. Before you perform a forced reboot, be sure to leave the phone charging for at least 30 minutes. After, press and hold the Volume Down button and Power button for about 10 to 20 seconds until the phone reboots.

Verify if it’s a screen issue

The next troubleshooting step that you want to do is to check whether the phone is totally dead, or if it’s a screen problem. This is done by looking for signs of life. If the phone makes sound notifications or vibrates when you try to restart it, those are signs that it’s not totally unresponsive. Or, you can try to call your number from another phone to check if your phone rings or vibrates. If it does show that it’s not dead but the screen stays black throughout, there must be a problem with the screen.

Restart to Safe Mode

To see if a downloaded app is preventing Android from booting up correctly, you can try to restart the phone to Safe Mode instead of normal mode. On this mode, all downloaded apps will be suspended. So, if the phone boots up fine on safe mode, you can bet you have an app issue.

  1. Turn off your Huawei Mate 20 Pro.
  2. Press and hold Power button.
  3. Release Power button and hold Volume Down Key. (When you see the Huawei animation)
  4. Hold Volume Down Key.
  5. Release Volume Down key and unlock your Huawei Mate 20 Pro.

Remember, safe mode blocks third party or downloaded apps. If the problem goes away in safe mode, you can bet one of the apps is to blame. To identify which of your downloaded apps is causing the problem:

  1. Exit safe mode by restarting your device.
  2. Check for the problem.
  3. If the problem returns, boot to safe mode again.
  4. Uninstall an app. Start with the most recently downloaded one.
  5. After each removal, restart your device and see whether removing it solved the problem.
  6. Repeat steps 1-4 until you’ve identified the culprit.
  7. After you remove the app that’s causing the problem, you can reinstall the other apps that you removed.

Charge thru a computer (optional)

Some Huawei Mate 20 Pro were able to fix charging issues by charging their device thru a computer for a few hours. If you haven’t tried this yet, make sure to leave the device connected to your computer for a few hours to see if there’s a difference.

Charge using portable charger (powerbank)

Aside from charging using a computer, you can also check how the device works when charged via a powerbank. If you have a powerbank, make sure to let the device charge for a couple hours.

Perform a master reset

If you are lucky and the cause of the problem is due to an unknown software bug, factory reset may help. Follow the steps below to refresh the system and set it up as a new device.

  1. Turn off the phone. If you are positive that the phone is currently off, charge it for at least 30 minutes before attempting the rest of the steps below.
  2. After that, press Volume Up and Power keys together for a few moments
  3. Release all buttons when Recovery Mode pops up. If nothing pops up or if Recovery Mode screen won’t show, repeat Steps 1-3. If nothing still works after multiple attempts, that’s a sign that your phone may be totally dead. It’s useless to continue with the steps below so skip them and send the device in for repair.
  4. Now select “wipe data/factory reset” by using Volume keys to scroll down and the Power button to accept it.
  5. In this mode choose “wipe data/factory reset” and confirm with the Power key.
  6. At the end select “reboot system now” with the Power button.
