最新Nexus 6p线刷升级教程

我的手机是Nexus 6p，原生系统Android 7.2 ~ Andriod 8.1下都执行成功。

1.解决adb和fastboot驱动

驱动下载地址【Download ADB, Fastboot – Android SDK Platform Tools】，或者到【百度云盘-adb-fastboot-v1.0.39.zip】下载。下载完成后解压，然后执行下列操作：

32位操作系统：

1.将adb.exe、fastboot.exe复制到C:\Windows\System32 ；
2.将adb.exe、AdbWinApi.dll、AdbWinUsbApi.dll、libwinpthread-1.dll复制到C:\Windows\System；

64位操作系统：

1.将adb.exe、fastboot.exe复制到C:\Windows\System32 ；
2.将adb.exe、AdbWinApi.dll、AdbWinUsbApi.dll、libwinpthread-1.dll复制到 C:\Windows\System；
3.将adb.exe、AdbWinApi.dll、AdbWinUsbApi.dll、libwinpthread-1.dll复制到C:\Windows\SysWOW64；

执行下图所示命令，结果如图，则说明驱动安装成功：

2.开启oem解锁

到手机设置里的开发者选项中，找到OEM unlocking选项，并启用，如下图：

3.进入bootloader模式

进行这一步的前提是先解决了adb和fastboot驱动，然后执行adb reboot bootloader，设备将进入bootloader模式。过程很快，此模式下界面显示Start。

4.oem解锁

设备进入bootloader模式后执行fastboot oem unlock（如果没用就执行fastboot flashing unlock），设备将进入解锁界面，音量键进行选择，电源键确认YES，解锁开始，过程很短。

5.刷机

刷机之前首先需要到官网下载最新的线刷包Factory Images，下载完成后，解压所有文件放到C:\adb，然后cmd终端进入C:\adb目录并执行命令，即可开始刷机过程：

耐心等待结束后，最后按任意键退出！

6.oem上锁

上面的步骤刷机成功后，手机的OEM还是处于解锁状态，处于解锁状态的手机，每次重启设备都会有安全提醒。

这样情况我们可以再执行上锁，刷机成功后，对手机进行设置，进入系统。在系统设置里，点击5次”Build number”，进入开发者模式。然后启用开发者USB调试模式。

接下来，用数据线连接手机，依次执行下列命令：

adb reboot bootloader

fastboot flashing lock

上锁完毕，电源键点击START进入手机设置，进入系统后还是开启开发者模式，进入开发者选项，找到OEM unlocking选项 ，取消启用。
