The Android 5.1.1 LMY47B official ota update is now live for the Google Nexus 5 devices. Check the instructions listed in this post in order to learn how to successfully install the new firmware manually.

Android 5.1.1 is being released over the air and, since it is done in phases you might not receive it at the same time as all the other users and you will be forced to look at alternative OS updating methods. Before starting the update you will have to read these guidelines:

  • this guide works only with the Nexus 5 users.
  • your Nexus 5 should be running on Android 5.1 with the following firmware versions: LMY47D or LMY47I.
    - do not use this post with any other Android devices.
    - don't flash Android 5.1.1 LMY47B / LMY48B over any older firmware files than LMY47I or LMY47D Android 5.1 builds.
    - the Android 5.1.1 LMY47B is for Android 5.1 LMY47I.
    - the Android 5.1.1 LMY48B is for Android 5.1 LMY47D.
  • if your device runs on a different firmware, then the updating process won't work and you should look elsewhere for a way to upgrade to Android 5.1.1 firmware.
  • the model and firmware version of your device can be checked under Settings> About Phone.
    - if your Nexus 5 meets the specifications, then you can continue to the next part of this post.
  • enable USB Debugging on your device in Developer Options.
    - if you can't find Developer Options, then you should enable it first.
    - go to Settings> About Phone and tap 7 times on the Build Number section.
    - return to Settings menu, scroll down and there you will find the Developer Options.
  • this guide has to be used only by advanced users, we cannot be held responsible in case you end up losing any data in the process nor in case you brick your phone.
  • backup all important data before starting the update.
  • check the battery charge level and make sure that it is over 50%, so that it prevents the device from powering down during the installation.
  • read the whole guide and do not skip any steps.

Since you've read all of the above you can continue to the next part of this post and learn how to setup the Android SDK first. Here's how to configure Android SDK:

  • download the Android SDK ADT Bundle from here.
  • extract the contents of this zip on your PC.
  • open the newly created folder and launch SDK Manager exe.
  • confirm the download and installation processes of all the SDK packages.
    - after these files are installed you should find a 'platform-tools' folder.
    - remember where the platform-tools folder is saved as you will have to use it later.
  • download and install the Google USB Drivers on your computer.

Now that you know all that you can continue to the installation instructions.
