Android 升级/刷机攻略（Google原生系统Pixel）

由于Google在五月份的I/O大会上新发布了Android P 9.0系统，公司需要测试APP在9.0上的兼容，因此拿到Pixel升级系统。

因为考虑到刷机开发版后无法再检测到更新，所以就还是尽量升级到Beta版。

（此教程也适用于Android Q）

升级到Android Beta版

升级到Android Beta最新版，相比刷机的优势在于，后续系统还能继续检查到更新，自动升级

加入Android Beta的计划：（当然要访问这个地址是有一定难度的）

https://www.google.com/android/beta?hl=zh-cn

查看符合条件的设备类型。

登录自己的Google账户，就可以查看是否有符合要求的设备

如果发现自己的设备明明是支持的，但是没出现在这个列表里面，却提示如下：

可以在手机设备上重新登录自己的账户。

同意升级到Android Beta的协议，同意后一般24小时内手机检查更新时即可检查到最新Beta版的更新包。手机上检测到新的更新包时，点击update即可。

我从同意协议到设备能检测到更新大概一小时的时间。

升级完成，重启。就OK了，升级到Beta后如下：

刷机到Android P 版

去官方下载固件包：（注意要针对自己的机型去下载）

https://developer.android.com/preview/download?hl=zh-cn

Android Q的镜像在：https://developer.android.com/preview/download.html

将下载后的ZIP包，解压，然后放置Android sdk目录下的platform-tools文件夹里，E:\Android sdk\platform-tools

按照刷机说明操作：

https://developers.google.com/android/images?hl=zh-cn#instructions

a、通过USB将设备连接到计算机，adb devices能够看到设备连上即可。

b、使用以下方法之一以快速启动模式启动设备：

c、使用adb工具：在设备启动的情况下，进入Bootloader模式

adb reboot bootloader

或者使用按键组合：关闭设备，然后将其打开并立即按住设备的相关按键组合。 d、解锁设备：

fastboot flashing unlock

对于旧设备，运行：fastboot oem lock

pixel 2上操作：

理论上会成功，但是我这边一直提示“flashing unlock is failed”

后来查了下，原因是开发者选项中“OEM解锁”选项的原因，需要关闭。但是这个选项一直是置灰的，所以无解。希望其他的小伙伴成功了的可以支招。

pixel 3上操作：

成功，可以看到明确提示，devices unlocked

接下来是Google的官方教程。

e、进cd 命令，进入到刚才解压缩的platform-tools目录中，执行flash-all。

Mac/linux下面直接将flash-all.sh拖到终端即可，Windows系统下双击flash-all.bat f、脚本运行后，可以看到终端里有操作的进展

g、完成后，设备将重新启动。已经刷机成功，看到系统升级到最新Android Q

f、安全起见，再对设备进行加锁

fastboot flashing lock

至此，刷机完毕。
