This guide below will teach you how to flash anAndroid 5.1 factory image for your Nexus 5, but you should know that it will ‘factory reset’ the device in the process. However, note that you can work around the ‘factory reset’ process by modifying the Nexus 5 installation script file before starting the flashing process – you will find more about this in the tutorial.

Before starting the installation you need to check the guidelines below:

• use this post only for the Google Nexus 5 smartphone.
  – do not attempt to install the factory image that you will find in this post on any other different device.
• in case your Nexus 5 is rooted or it runs on a custom Recovery, then you should know that the process will remove these changes from your device.
• the installation of Android 5.1 Lollipop LMY47D factory image will restore your device to its stock state.
• you will also be asked to ‘unlock bootloader’ during process.
  – if your device is on an unlocked bootloader already, then you won’t lose the data that’s stored on your device.
• make sure to backup and save all the important files before starting installation.
• in the tutorial you will find a small workaround that teaches you how to avoid the ‘factory reset’ process.
  – every time someone installs a ‘factory image’ on their device the flashing process usually wipes clean the smartphone, but you can avoid that.
• if your device sports a custom ROM now, then you can’t avoid the ‘factory reset’ process, which means that you will lose all data from your phone and your device will be restore to its original state.
• enable USB Debugging for your device from Developer Options before starting Android 5.1 LMY47D factory image installation.
  – if Developer Options doesn’t appear under Settings, then you should go to About Phone and tap 7 times on ‘build number’ section.
  – after Developer Options is unhidden you will find it in Settings menu, scroll down and open it, then enable it and tick the ‘usb debugging’ option.
• check the phone’s battery charge level, make sure that it is over 50% so that your Nexus 5 won’t power down during the installation process.
• this is a tutorial that has to be used only by advanced Android users.
• we cannot be held responsible in case you lose any data nor in case you end up bricking your Nexus 5.
• read the whole guide and don’t skip any steps.
• in case you need more help completing the guide you should use the comments field.
