Galaxy Nexus IMM76K 手动升级 4.1.1

手上 Galaxy Nexus是 IMM76K，一直等不到OTA升级。查了一下，这是三×来管理的OTA的机器，Google不管。是后娘养的。只好自己动手回到Google箮理之下。

前提升级需要在Linux  下，我的电脑装的Arch

升级过程非常简单。

英文的升级说明：

Instructions

You will find these files useful if you have used the Android Open-Source Project, flashed custom builds on your device, and wish to return that device to its factory state.

In order to use these files, you need to have the fastboot tool in your PATH. That tool is compiled as part of every configuration of the Android Open-Source Project and is the tool used to flash custom builds on your device. On GNU/Linux systems, this also implies that you have configured USB access as mentioned in the machine setup instructions.

Your device needs to be in fastboot mode, with the bootloader unlocked. The relevant key combinations and commands are documented on the page about building for devices.

You need to uncompress each download before use, which creates a new directory for that exact download. That directory contains a ./flash-all.sh script, which handles the various operations, installs the necessary bootloader, baseband firmware(s), and operating system. Note that this operation deletes all user data by default.

After restoring a factory image, it is recommended that you lock the bootloader, for security reasons.

我的操作步骤，总共5步
