Install Android 6.0 Marshmallow (MRA58K) factory images on Nexus 5, 6, 7, 9 and Nexus PlayerGoogle

Google has just released the Android 6.0 Marshmallow factory images with build number MRA58K for a spate of Nexus devices including Nexus 5, Nexus 6, Nexus 7, Nexus 9 and Nexus Player. Nexus 4, Nexus 10 and the 2012 Nexus 7 are yet to receive Google's latest Android update.

Here is a checklist of prerequisites that need to be taken care of, before you proceed to upgrade your Nexus device to Google's newest operating system:

Prerequisites

  • This guide involves the use of ADB tools and hence it is imperative that you make sure that ADB tools are installed on your computer (download Android SDK).
  • Ensure that your Nexus device is visible on your computer. Launch Terminal app and type the command "adb devices" and hit Enter. If the device is listed there, you are all set. Otherwise, just ensure your device has USB debugging option enabled in the Settings app:
  • Go to Settings > About Phone > tap the build number a few times and then hit the back button > Developer Options. The USB debugging option should now be accessible.
  • Backup your important data and settings on the Nexus phone or tablet.
  • Verify that your device's bootloader is unlocked by navigating to Settings > Developer Options > About page and tap the Android build number several times on your Nexus smartphone or tablet. Then make sure OEM unlocking is checked. Enter the command "adb reboot bootloader" to go to device's bootloader and check if it is in locked state. If the device is locked, return to the bootloader screen and enter the "fastboot oem unlock" command.
  • Accept the various confirmation-prompts to unlock your device and hit OK when a prompt suggests that all data will be wiped on your device.
