Download Android SDK

  • http://developer.android.com/sdk/index.html

  • "SDK Tools only" is ok enough, choose corresponding version based on your host to download. Here use Windows 7 as host

  • Just install it

    Download Android L Preview package

  • http://developer.android.com/preview/setup-sdk.html

  • Choose the image for Nexus 5 and download:"hammerhead"

    *   [hammerhead-lpv79-preview-ac1d8a8e.tgz](http://developer.android.com/preview/setup-sdk.html#top)

    Prepare Nexus 5

  • Power off Nexus 5

  • Press "Volumn down" and "Power" button to power on

  • Connect Nexus 5 to Windows through USB line

    On Windows 7, flash Nexus 5

  • Find where the just SDK was installed. In fact mainly to find where the "fastboot.exe" was installed. On my test environment it's "c:\Users\USER\AppData\Local\Android\android-sdk\platform-tools\fastboot.exe"

  • Open Windows Explorer, go to the folder just mentioned above. Extract the just downloaded .tgz file to it. After extracted, you should see files like "flash-all.bat" are in the same folder of "fastboot.exe"

  • Open Command using Administrator permission, go to the folder just mentioned above. Run "flash-all.bat". Wait for some time (around 5min, depends on cases). Then Nexus 5 reboot. Now could disconnect the USB line.

  • Enjoy!
