The process will delete all of your data stored on the memory box so its better to back it up. To complete this process you need to know the risk involved and you can easily flash the latest version of Lollipop 5.1 to you Nexus device.

Install Lollipop 5.1 On Your Nexus Device

  1. On your Windows computer, download and install the most recent version Android SDK. Two programs will be installed Fastboot and ADB. To access these files you have to open them through the command terminal on you windows PC as a slice of the development kit in software.
  2. Put the SDK folder in the path provided by the steps below:- Open Properties by right clicking on My Computer- Open Advanced Sysytem Settings- Open System Properties >> Advanced >> Environment       Variables- Select path in the Window then edit it and type the location where SDK is installed. Do remember to put a semi-colon to separate each entry.
  3. The USB debugging on your device should be enabled. To do so, go to Settings >> About Phone >> Software Information
  4. Build Number is to be tapped 7 times
  5. Them go to Settings >> Developers Options. Check the USB debugging option
  6. This is where you download the factory image for your Nexus variant. The links are provided below after this section of steps.
  7. Extract image On Windows PC
  8. Connect Device to PC via USB
  9. Start your device in the fastboot mode

Nexus 5 has a different way to do it. You must press and hold down the volume up and volume down keys along with the power button when you power your Nexus 5 on. You can also use ADB to boot into the Fastboot mode. You can do this by powering on your device, go to command terminal and execute adb reboot bootloader. If needed, through your computer you must unlock your device’s bootloader by using the command terminal and launching ‘fastboot oem unlock’.

  1. Find the path to the unzipped image file or directory using command terminal
  2. Flash-all.bat should be executed which is part of the unzipped image. This scripture would install the basic baseband firmware/s, bootloader and operating system. This will only work when you have added that folder where Fastboot and ADB are installed to system path as shown in step 2
  3. When you do this, lock the bootloader as recommended by Google for security. This can be done by booting your device when still connected to USB in fastboot mode. Then use the command terminal to execute the ‘fastboot oem lock’.

Even though these steps will install the Lollipop 5.1 version to your Nexus device we would still recommend you to wait for the final release for the OTA update. Installing the OTA update is a trouble free workout to upgrade your OS. If you have any question let us know in the comments.
