- Download Android L image for your device:
- Unzip the files twice. e.g. there’s a .tar file and there’s a .tgz file inside that, you will need to extract both in order to get the .img file according to your device.
- Once you’ve got the .img file, copy it to the Minimal ADB and Fastboot folder, that’s probably here C:\Program Files (x86)\Minimal ADB and Fastboot
- Now connect your Nexus device to your PC in fastboot mode. In order to do so, power it off and connect it to your PC. Now turn it on by pressing and holding Volume Up and Volume Down + Power Key.
- If this doesn’t work for you, simply open the Minimal ADB and Fastboot.exe file that should be on your desktop and type:
adb reboot bootloader
- Once the device is in bootloader, checkout if the bootloader is unlocked or not. In case the state says “Locked” you need to unlock it first by typing:
fastboot oem unlock
- It should now ask you whether you want to unlock the bootloader or not. You can switch between the Yes or No options by using Volume Up and Down Keys and make a selection using Power Key.
- Unlocking will wipe your device, so make sure that you’ve already backed up everything as mentioned in the pre-installation instructions.
- Once the bootloader is unlocked, you’re set to flash Android L on your Nexus device.
- To do so, push this command in the Minimal ADB and Fastboot Command Interace:

- You can lock the bootloader again by booting up your device in the bootloader mode and issuing the command:
fastboot oem lock
