●Confirm that the network is in good condition.
●Restart the HUAWEI Mate 30/use Mobile Manager's one-click optimization or clean-up acceleration.
●Try to continue downloading after emptying the cache of system updates / software updates.
●If none of the above methods can solve the problem, you can back up the data, restore the HUAWEI phone to factory settings, and then try to update the system.
This problem is caused by the incomplete installation package due to the poor network during the download process. You can download the installation package again in a WLAN or network-friendly environment.
This is due to the power outage of the HUAWEI Mate 30 during the upgrade process (such as long pressing the boot button), resulting in the upgrade failure to enter FASTBOOT mode, unable to boot normally.
Solution: connect the HUAWEI Mate 30 phone to the computer (please first try to use the mobile assistant to back up the data), click "system repair > continue > start repair" on the mobile assistant (the system will be repaired until the specified version cannot be selected). The repair process will take time, please wait patiently.
●During the repair process, please do not disconnect the USB data cable, manually shut down the phone, restart the phone, plug or unplug the SD card and other operations (such as the repair failure caused by restarting the phone, please do it again).
●Theoretically, it will not cause data loss, but it is still recommended that you back up the data in advance.
