If you cannot receive the system update installation package, refer to Unable to receive system update notifications on my HUAWEI phone/tablet.

After removing the SD card, make sure that the battery level of the device is higher than 20% and the memory is sufficient. If the update still fails after the preceding conditions are met, perform the following operations:

When downloading the update package, the progress bar does not respond for a long time, or messages such as "Download failed", "Installation package verification failed", "Server unavailable, please try again later", and "Installation package parsing failed" display. This may be caused by an unstable or restricted network connection. To resolve this issue, perform the following steps:

1. Open Settings, search for Apps, find System update or Software update in the app list, go to Storage > Clear data, restart the device, and download the update package again when the network environment is good.
2. If the download still fails, back up your data, restore your device to its factory settings, and try again.

1. It takes time for updates to complete, especially when there are a large number of apps on the device, or when the update package is large. Remember to be patient, and wait for the update to complete.
2. If you press and hold the Power button or perform other operations on your phone during the update, your device will re-enter the update screen. Please be patient, and wait for the update to complete.
3. If the update still fails, use HiSuite to restore the system.

1. If your phone is stuck on the logo screen for an extended period of time, charge it for at least 30 minutes, then check to see if you can power it on.
2. If the phone still cannot be powered on properly, press and hold the Power button for 10 seconds to force restart it (for the Mate 40 series, press and hold the Power and Volume down buttons for more than 10 seconds).
3. If the issue persists, restore the system.

If the following situations occur during the update:

• Update fails, and red text displays on the startup screen, rather than redirecting to the home screen.
• During the update, the device automatically restarts and then enters the update screen. The message "Software install failed" displays along with a red exclamation mark.

It is recommended that you restore the system.

Restore the system

Restoring the system may erase your personal data. If your device can be powered on, remember to back up your data immediately.

• Repair the system via eRecovery.
  1. Connect the device to a charger, ensure that the device is being charged. Power it off, and press and hold down on the Volume up and Power buttons. Once the device vibrates, go to Update mode > eRecovery mode/eUpdate mode. (To trigger eRecovery mode/eUpdate mode on Mate 30 Pro and Mate 30 RS that do not have physical Volume buttons, press the Power button 5 times consecutively after the phone vibrates during startup.)
  2. Go to Download latest version and recovery > Download and recovery to have your device search for available Wi-Fi networks. The update package will be automatically downloaded once you are connected to an available Wi-Fi network.
  3. Once automatically downloaded, the device will restart to complete the update. The update may take a short while. Remember to avoid using your device during this process.
