一、问题描述

如下图，Google Nexus 6刷机刷残了，开机就是这个界面，┭┮﹏┭┮…
度娘说是系统损坏，导致不可信，然后我按了【电源键】，手机直接关机！！！

二、解决方案

1. 准备工作

（1）准备一个配置好adb和fastboot工具的PC机，adb tools工具下载链接，Win 7环境配置教程&Win 10环境配置教程；
（2）手机和电脑可通过USB连接，并可进入Fast Boot Model。
（3）下载Google Nexus 6的系统镜像，例 shamu-mra58k-factory-0c8cee76.zip，下载链接。

2. 系统安装

做好准备工作后，解压镜像文件，开始下述步骤。

# 命令行进入fast boot model，如无效，可将手机关机后，同时按【电源键】+【音量下键】。
adb reboot bootloader 
# 若机器是15年以前生产，执行以下命令
fastboot flashing unlock
# oem解锁
fastboot oem unlock
# 双击解压包中flash-all脚本文件，自动执行系统安装

若上述过程执行完毕，仍无法正常开机，解压image-xxxx-xxxx.zip文件，进入解压后的文件夹，执行以下步骤。

# 依次安装下述镜像
fastboot flash recovery recovery.img
fastboot flash boot boot.img
fastboot flash system system.img
fastboot flash cache cache.img
fastboot flash userdata userdata.img
# 手机重启
fastboot reboot

执行过程中，命令窗提示如下。
