How to download and manually install Android 5.1 Lollipop on Google Nexus 5, Nexus 7, and Nexus 10?

Google on Monday started rolling out the first major update to its Android 5.0 Lollipop operating system. The update, Android 5.1 Lollipop, will be rolled out to a variety of devices, with the Nexus series being the first in line to receive the latest version. Nexus 5, Nexus 7 Wi-Fi and Nexus 10 are the three devices that will get this update first as Google has posted Android 5.1 Lollipop factory images for these devices on its website. If you can’t wait for the OTA update to arrive, you can use these images to install Android 5.1 Lollipop on your device.

You can manually download and install the Android 5.1 Lollipop factory image from Google’s website. This procedure is not recommended for anyone but the most advanced users with little technical knowledge. This process will erase all your data, so make sure you back up your Android device first. If you understand the risks and own a Google Nexus 5, Nexus 7 Wi-Fi or Nexus 10, you can use these steps to flash the latest version of Android Lollipop on your device.

    1. Download and Install latest android sdk on your Windows computer. It installs two programs, adb, and fastboot, which can be accessed through the command terminal on your PC as a part of the software development kit.

    2. Add the SDK folder to the path by following these steps:

    • right click my computer and click Property,
    • click on advanced System Settings,
    • click on System Properties > Advanced > Environment Variables,
    • In the window, select waythen click editAnd then type the name of the directory where you installed the SDK, and remember that each entry is separated by a semi-colon.

      3. Enable USB debugging on your device. First, go to Settings > About phone > Software information,

      4. Tap build number seven times.

      5. Go Here Settings > Developer Options, tick USB debugging,

        7. Extract the image to your computer.

        8. Connect your device to your computer via USB.

        9. Start the device in fastboot mode.

        For Nexus 5, press and hold the volume up, volume down and power button while the device is on. A full list of key combinations for different instruments can be found at Here,

        You can also boot into fastboot mode using the adb tool: With the device turned on, go to the command terminal and execute the following: adb reboot bootloader

        If necessary, unlock the device’s bootloader through your computer using the command terminal and execute: fastboot oem unlock

        1. Open a command terminal and navigate to the unzipped system image directory.

        2. Execution flash all.bat, which was part of the unzipped image file. This script installs the required bootloader, baseband firmware(s), and operating system. For this to work, you need to add the folder where adb and fastboot are installed to the system’s path as described in step 2.

        3. When this is done, Google recommends that you lock the bootloader for security. You can do this by booting the device into fastboot mode while connected via USB, and using the terminal command to execute: fastboot oem lock.

        Even though this method will install Android 5.1 Lollipop on your Nexus device, we still suggest that you wait for the OTA update to ensure a hassle-free update process.
