Nexus 5更新 Android5.0 失败解决方法

标签：android5.0

Android 5.0终于推出了正式版，今天也及时刷到了Android5.0 (LRX21O)，官方链接：https://developers.google.com/android/nexus/images

镜像下载地址：https://dl.google.com/dl/android/aosp/hammerhead-lrx21o-factory-01315e08.tgz，MD5：761667f1ddaf4e38d4792136df4ab927，SHA-1:01315e08c7f282452b5eba0606dd5a2d5274edde。

刷机步骤如下：

1、解压下载好的.tgz包

2、解压faseboot包，并将里面的内容复制到解压好的tgz包的文件目录中

3、手机关机，同时按住开机键和音量-

4、双击执行flash-all.bat。执行过程中出现了问题：archive does not contain ‘boot.sig‘；archive does not contain ‘recovery.sig‘；failed to allocate 717308456 bytes；error: update package missing system.img；

解决方法：编辑flash-all.bat，注释掉“::fastboot -w update image-hammerhead-lrx21o.zip”，即在此行前加“::”，然后增加以下代码：

fastboot flash boot     boot.img
fastboot flash cache cache.img
fastboot flash recovery recovery.img
fastboot flash system   system.img
fastboot flash userdata userdata.img
fastboot reboot

整体代码修改为：
