Nexus 5更新 Android5.0 失敗解決方法

刷機步驟如下：

1、解壓下載好的.tgz包

2、解壓faseboot包，並將裡面的內容復制到解壓好的tgz包的文件目錄中

3、手機關機，同時按住開機鍵和音量-

4、雙擊執行flash-all.bat。執行過程中出現了問題：archive does not contain 'boot.sig'；archive does not contain 'recovery.sig'；failed to allocate 717308456 bytes；error: update package missing system.img；

解決方法：編輯flash-all.bat，注釋掉“::fastboot -w update image-hammerhead-lrx21o.zip”，即在此行前加“::”，然後增加以下代碼：

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

整體代碼修改為：
