Google has issued the Android 6.0 Marshmallow Update over-the-air for all Nexus 5 users. This tutorial is destined for those Nexus 5 owners that are looking to skip the waiting time and update their phone manually using "adb sideloading" process.

The new Android 6.0 firmware brings tons of changes and improvements for your smartphone, so you should upgrade right away. Before starting the updating process you should check the guidelines below:

  • use this post only with the Google Nexus 5 smartphones.
  • your phone should be running on the Android 5.1.1 LMY48M Lollipop firmware for this updating tutorial to work with your phone.
  • do not try to use this post with any other different Nexus devices.
    - also, don't flash the new update build over an older Lollipop build than the LMY48M version.
  • check the model and the firmware version of your device under Settings> About Phone menu.
  • make sure to enable the USB Debugging from Developer Options menu.
    - the Developer Options might be hidden, so you will need to enable it by going to Settings> About Phone and tapping 7 times on the Build Number section.
    - return to Settings menu and there you will have Developer Options, open it and find USB Debugging to enable it too.
  • for the updating process to work your device has to run the Android 5.1.1 LMY48M 100% firmware.
  • if your device has a custom ROM installed on it or any other type of OS modification, then the update process is not going to work.
  • use this tutorial only if you are an advanced Android user, we cannot be blamed in case you brick the phone nor in case you lose any important files.
  • check the battery charge level of your device and make sure that it is over 50%, it will prevent the device from powering down during the first boot process of Android 6.0 OS.
  • read the entire tutorial and make sure not to skip any steps.
