Nexus 5更新 Android5.0 失敗解決方案

標籤：android5.0

Android 5.0終於推出了正式版，今天也及時刷到了Android5.0 (LRX21O)，官方連結：https://developers.google.com/android/nexus/images

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

刷機步驟如下：

1、解壓下載好的.tgz包

2、解壓faseboot包，並將裡面的內容複寫到解壓好的tgz包的檔案目錄中

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；

解決方案：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：
