由于单个刷机过程复杂，因此，我们可以编写一个刷机脚本来更加方便快捷地进行刷机操作。以下是华为P40刷机脚本的示例代码：

#!/bin/sh
#This script is used to upgrade the rom of Huawei P40

echo "Insert your Huawei P40 device into your local PC"
adb devices
adb reboot-recovery

echo "waiting for device to boot into the recovery mode..."

sleep 15
echo "starting upgrade process, please do not unplug your device..."
adb sideload update_rom.zip 

echo "update process completed, reboot device..."
adb reboot
