相关文章：【android Framework 探究】android 13 aosp编译全记录
写在开始
书接上文，编译完后，在二手平台挑挑拣拣最终下手piexl 5，这就开始迫不及待的烧录。
一，解锁bootloader
如果之前已经解锁可以跳过这步
- adb reboot bootloader
- fastboot devices （查看设备是否就绪）
查看 Device States为“lock”再进行如下解锁操作，如果已经是“unlock”,说明已经解锁解锁，直接开始烧录即可。
- fastboot flashing unlock
使用手机音量键切换，Unlock the bootloader，按电源键确认，解锁后，Device States为“unlock”
二，烧录
- 设置环境变量
/home/{usr name}/{build directory}/out/target/product/{taget}
如上格式设置环境变量。我的如下：
export ANDROID_PRODUCT_OUT=“/home/wu/GitProjects/aosp/out/target/product/redfin”
- fastboot -w flashall
烧录过程中重启属于正常现象，如下输出说明烧录成功。

遇到的问题
fastboot -w flashall 报错
fastboot: error: could not read android-info.txt
解决方法
export ANDROID_PRODUCT_OUT ，请设置绝对路径，发现我出错时用的
～/来代替/home/{usr name}
三，刷原厂镜像包
按照上面的方法刷完之后，你会发现原生UI实在是太丑了。也为了防止刷机出现意外情况，需要恢复系统，你可以提前准备好google原厂系统镜像包，在需要的时候刷回去。
解压后，执行./flash-all.sh即可，出现如下提示：
< waiting for any device >
新打开一个命令框执行adb reboot bootloader，等待重启后，就自动执行刷机操作了。
最后
连接wifi提示网络受限解决：
adb shell settings put global captive_portal_http_url http://connect.rom.miui.com/generate_204
adb shell settings put global captive_portal_https_url https://connect.rom.miui.com/generate_204
执行完，切为飞行模式，再切换回来。
