In order to root your Nexus with Android 5.0 Lollipop only must download the version for your device and follow the steps

Before continuing with the procedure, it is necessary to activate the Options Developer, for it Settings> About Device and press more than 7 times in a row the number Compilation until a message is displayed notifying the developer options are enabled.

WARNING sometimes command of the root can delete all your information so I recommend making a backup before performing the process

Then from your device go to Options developer and check the box Enable OEM unlocking / permit OEM unlock and then below on or tick the  USB Depuracion.

Steps:

  1. Unzip the ZIP file to produce a file called root-windows.bat
  2. Connect the device to the computer itself fastboot mode and efficiently execute previous file
  3. You will then need only disconnect the device and restart.

Another method Root if this were to not work is to use the Nexus Root Toolkit has been updated and is now compatible with Android 5.0 Lollipop

If you followed the steps correctly and we rooted our Google Nexus with Android 5.0 Lollipop .

Error Missing system.img

If you were already very excited about this great fresh-install version Android , and you met a problem that is affecting many users trying to install the image produced here is the solution.

Flash the bootloader and radio (radio does not appear at all, if you are in the tgz not need it)

fastboot flash bootloader <bootloader file name here> .img
fastboot flash radius <radius file name here> .img

Then we need to restart the bootloader to load the new version, do not skip this step!

fastboot reboot-bootloader

Now just follow the following commands:

fastboot flash recovery recovery.img
fastboot flash boot boot.img
fastboot flash system system.img

if you have a Nexus 9 includes this command

fastboot flash vendor vendor.img Then if we clear the cache and user data (clear all), we have to flash this:

fastboot flash cache cache.img
fastboot flash userdata userdata.img

Finally, we have to restart your Android device to boot with the new version
fastboot reboot

Guests Internal Memory

if after flashing the userdata.img your internal memory is reduced to 16GB , you should only enter the recovery and make another Full wipe, with this the error is resolved.

 

 That’s all, it can have the latest available version of Android 5.0 Lollipop for some Nexus devices, as released the full update for all devices and update the note.
