【Nexus 5更新 Android5.0 失败解决方法】蹉跎莫遣韶光老，人生唯有读书好。这篇文章主要讲述Nexus 5更新 Android5.0 失败解决方法相关的知识，希望能为你提供帮助。
android 5.0最终推出了正式版，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。
刷机过程例如以下：
1、解压下载好的.tgz包
2、解压faseboot包。并将里面的内容拷贝到解压好的tgz包的文件文件夹中
3、手机关机，同一时候按住开机键和音量-
4、双击运行flash-all.bat。运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。凝视掉“::fastboot -w update image-hammerhead-lrx21o.zip”。即在此行前加“::”，将image-hammerhead-lrx21o.zip解压开。然后添加下面代码：
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


总体代码改动为：
