google Nexus 和 Pixel 设备刷机

Flashing instructions 刷机步骤

下载

  1. 下载对应机型的刷机文件，例如，Nexus 5X 对应的 bullhead 的刷机包 bullhead-opm1.171019.011-factory-3be6fd1c.zip ， 有1G大小呀
  2. 下载最新的刷机工具 fastboot.exe 包含在 Android SDK Platform-Tools package 中。

配置

  1. 将 fastboot.exe 配置到 PATH 中，以便刷机脚本能找到它

进入 fastboot 模式

  1. 通过 usb 连接手机和电脑
  2. 设置手机进入 fastboot mode ，根据如下几种方法：
    1. 手机开机状态执行 adb reboot bootloader
    2. 使用组合键：关机 》开机 并立即按下组合键，参考 如何进入fastboot模式
      • Nexus 5X的组合键：按住【音量下】，然后按住【电源键】

解锁 bootloader

  • 2015年及以后的设备 (例如：Nexus 5X, Nexus 6P, Pixel, Pixel XL, Pixel 2 or Pixel 2 XL device): 
    1
    fastboot flashing unlock

  • For Pixel 2: To flash the bootloader, Pixel 2’s boot loader must be updated to at least Oreo MR1’s version first. This may be done by applying an over-the-air (OTA) update, or sideloading a full OTA with the instructions on that page.

  • For Pixel 2 XL only: the critical partitions may also need to be unlocked before flashing. The unlock can be performed with this command, and should NOT be done on other devices: 
    1
    fastboot flashing unlock_critical
  • 其他老设备： fastboot oem unlock

结果成功，设备会跳出提示页面，说会删除所有数据。
