Install and root Android 5 on Nexus 5

I thought about the thing to have a rooted Nexus 5 with Android 5 but how??

The answer is: YES it is possible 😀 but Android 5 is for me not completely stable 😐 and it is stable 🙂

UPDATE: IF you have rooted your Nexus 5 with Andorid 5 your system will have an ram overflow after 5 to  15 minutes after power on!!!! – Wait with the update to Android 5 and the rooting of it.
I have tried it a second time and after that it works for me now fine.


I have installed the Android 5 on my Nexus 5 with the how-to from the Google developer: Factory Images for Nexus on my Xubuntu-Notebook.

  1. Download the last Android SDK with the “fastboot” application in the sub folder “platform-tools/” and define it as a PATH
  2. Download the factory-image for your Nexus 5 from the list on the Google developer site and extract that to a folder
  3. Connect your Nexus 5 to a computer
  4. Now you have to set your Nexus 5 in “fastboot mode”
    1. You can do it, by holding down the “power” + “volume up” + “volume down” buttons before pressing anything on your switched off phone.
  5. Now run the command “fastboot oem unlock” – that unlocks the bootloader and will delete any data on your phone.
  6. Open a terminal and navigate to the extracted system image directory
  7. If step 5 was without any problems then switch over that hole step if not and you use a linux computer then do that among
    1. Open with an editor the file “”
    2. Write at the second line: BOOT=/%dir to your%/fastboot
    3. Change every “fastboot” to “$BOOT”
  8. Now execute “flash-all” as root/admin – that will take some minutes
    1. Linux: ./
    2. Windows: flash-all.bat

Now you have a running Android 5 on your Nexus 5.

Now it is time to root your Nexus5:
To do that i have taken that how-to: Root Nexus5 & Nexus 7

  1. Check if your phone is “oem unlocked”
    1. If not then do step 4 and 5 from above
  2. Now set your phone to “fastboot mode” as the step 4 above
  3. Download “CF Auto Root”
    1. Nexus 5
    2. Nexus 7 2013
  4. Connect your Nexus to your computer
  5. Now execute “root-linux/windows”
    1. Linux: ./
    2. Windows: root-windows.bat

The CF Auto Root will install the “SuperSu” APP on you phone with that you can give other programs the right to do something with “sudo” rights.
