android - 如何使用adb root （解决　adbd cannot run as root in production builds )

参考：https://stackoverflow.com/questions/25271878/android-adbd-cannot-run-as-root-in-production-builds

今天在　执行　$ adb root 的时候遇到了问题．　adbd cannot run as root in production builds

1. 需要你的手机是root机

2. 下载这个zip 文件: ( https://github.com/evdenis/adb_root/releases )

3. 在magisk 中, 使用 "本地安装" 的方式, 安装这个zip 包. 重启

4. 用 专用的 USB 线 连接手机与电脑 ,并且开启开发人员选项, 选择 "传输文件" ( 不要仅充电)

5. $ adb root  即可！

注意: 还需要 $ su root 才行! 

否则会报错: permission denied. 

下面是证明

$ adb shell
merlin:/ # ifconfig
ifconfig: ioctl 8927: Permission denied
