准 备：
- MTK Easy SU V1.1.3
- MagiskManager-v8.0.4.apk
一、下载安装MTK easy SU，地址：https://github.com/JunioJsv/mtk-easy-su/releases ，版本按需选
adb安装和拷至手机安装都可：
C:tmpfastboot>adb devices
* daemon not running; starting now at tcp:5037
* daemon started successfully
List of devices attached
8T8XXXXXBU9PCM4S device
C:tmpfastboot>adb install c:/tmp/mtk-easy-su-v1.1.3.apk
Performing Push Install
c:/tmp/mtk-easy-su-v1.1.3.apk: 1 file p...hed. 5.2 MB/s (2857723 bytes in 0.525s)
pkg: /data/local/tmp/mtk-easy-su-v1.1.3.apk
Success
二、打开MTK Easy SU，手机联网，在Assets处选择一个版本的Magisk面具安装。（如果手机时间设置不准确，如比当前日期早3-5年，则可能看不到Magisk的安装列表）
三、安装完成后重新启动手机，不要用快速启动方式：
四、安装完后点击最下边的“ACTIVATE BOOTLESS ROOT”开始处理：
- 成功后，会短暂显示“Success”
- “Activate Bootless ROOT”会变暗
- 每次重启手机后需要再点击“Activate Bootless Root”获取root权限
五、root处理过程记录：

六、下载并安装面具MagiskManager-v8.0.4.apk，地址 https://github.com/topjohnwu/Magisk/releases
C:tmpfastboot>adb install c:/tmp/MagiskManager-v8.0.4.apk
Performing Push Install
c:/tmp/MagiskManager-v8.0.4.apk: 1 file...hed. 5.1 MB/s (3191190 bytes in 0.601s)
pkg: /data/local/tmp/MagiskManager-v8.0.4.apk
Success
七、使用，应用程序申请root权限时会弹出对话框，确认即可
注 意：
- 此操作适用android低版本
- 适用MTK手机
- 获取的是临时ROOT权限
我的类似文章：
- 安装Magisk面具，获取root权限，刷入手机永久生效
- 手机安装magisk获ROOT权限，无须第三方recovery
