由 假如想象 提交于 2020-02-08 04:25:57
一、引言 Recovery 模式指的是一种可以对安卓机内部的数据或系统进行修改的模式，（类似于 windows pe 或 DOS）。在这个模式下我们可以刷入新的安卓系统，或者对已有的系统进行备份或升级，也可以在此恢复出厂设置，本篇文章即来介绍下Rockchip中的recovery 二、Recovery 模式在框架层的位置 Android 启动后，会先运行 bootloader。Bootloader 会根据某些判定条件决定是否进入 recovery 模式。Recovery 模式会装载 recovery 分区，该分区包含 recovery.img。Recovery.img 包含了标准内核(和boot.img 中的内核相同)以及 recovery 根文件系统。 Android recovery 三个部分两个接口，recovery 的工作需要整个软件平台的配合，从架构角度看，有三个部分： Main System: 用 boot.img 启动的 Linux 系统，Android 的正常工作模式。 Recovery：用 recovery.img 启动的 Linux 系统，主要是运行 recovery 程序。 Bootloader：除了加载、启动系统，还会通过读取 flash 的 MISC 分区获得来自 Main System 和Recovery 的消息，并以此决定做何种操作。 两个通信接口：

Enrollment Challenge to retrieve UDID from iPhone

由 房东的猫 提交于 2019-12-30 02:28:09
问题 Ad hoc testing facilities like TestFlight and HockeyApp use a part of the iOS OTA enrollment process to retrieve UDIDs (and possibly other device information, such as device type). How do these services achieve this? I've already figured out how to provide an initial "profile service" payload to send to the phone. I receive a valid response from the phone via a POSt request. After that, I'm clueless, I keep getting an "Invalid profile" error. What am I supposed to send back? Do I really have

Looking through my code changes over the last several months,
