Android L

If you are like me, and can’t wait for the update, and get an error that said archive does not contain ‘boot.sig‘, just follow this steps:

1. Create a backup of your phone.

2. Download the Factory Image on these link: https://developers.google.com/android/nexus/images

3. Start the device in fast boot mode, one way to do this is:

  • Using a key combo: Turn the device off, then turn it on and immediately hold down the relevant key combination for your device. For example, to put a Nexus 5 (“hammerhead”) into fastboot mode, press and hold Volume Up + Volume Down + Power as the device begins booting up.

4. Extract all the file on the same folder

5. Run these commands manually:

  • fastboot flash bootloader bootloader-hammerhead-hhz12d.img
  •  fastboot reboot-bootloader
  •  fastboot flash radio radio-hammerhead-m8974a-2.0.50.2.21.img
  •  fastboot reboot-bootloader
  •  fastboot flash system system.img
  •  fastboot reboot-bootloader
  •  fastboot flash userdata userdata.img
  •  fastboot flash recovery recovery.img
  •  fastboot flash boot boot.img
  •  fastboot erase cache
  •  fastboot flash cache cache.img
  •  fastboot reboot
