Build and Flash AOSP 9 for Pixel XL (marlin)
前言
最近在打安卓隐私相关的工，所以需要编译一个 AOSP. 之前高中的时候觉得新奇而买的 Pixel XL 就派上了用处。
下载 AOSP 源码
因为 AOSP 源码极大，所以使用 USTC 的镜像源来加速
基本上和 初始同步方法 2 一样。要注意的是，其依旧会向 Google 请求数据，所以需要接入互联网。
这里采用的版本是 PQ3A.190801.002 | android-9.0.0_r46 | Pie | Pixel 3 XL, Pixel 3, Pixel 2 XL, Pixel 2, Pixel XL, Pixel | 2019-08-01
$ mkdir -p AOSP
$ cd AOSP
$ repo init -u git://mirrors.ustc.edu.cn/aosp/platform/manifest -b android-9.0.0_r46
$ repo sync --jobs=10
下载 Driver
打开 [Pixel XL binaries for Android 9.0.0 (PQ3A.190801.002)(https://developers.google.cn/android/drivers#marlinpq3a.190801.002) 下载并解压到 AOSP 源码的根目录并运行
~/AOSP$ wget https://dl.google.com/dl/android/aosp/google_devices-marlin-pq3a.190801.002-9ce9ce62.tgz
~/AOSP$ tar -xzvf ./google_devices-marlin-pq3a.190801.002-9ce9ce62.tgz

$ make -j $(nproc)

编译成功之后，打包 img 文件
$ cd out/target/product/marlin # 这是输出文件夹
$ tar -zcvf malin-9.tar.gz .
压缩的话不一定需要压缩这么多东西, tar -zcvf malin-9.tar.gz ./*.img 再加一些必要文件可能就可以了。实测下来压缩时间非常长，如果硬要全部打包可以用 pigz.
在 Windows 下刷机
用 choco install adb 或者其它方式安装 android debug tools
- 重启至
fastboot - 解压
