The official Android 5.1 Lollipop is out now and doing the rounds for the list of Google-owned nexus devices before the rest get the opportunity to flash the same. This time it’s the 2012 edition of the nexus 7 WiFi tablet that has the factory image available for you to install by following the easy guide below. make sure you check out the pre-requisites after the jump before getting started so you don’t miss what you need before installing the LMY47D firmware build.

REQUIREMENTS

  • As you probably know, the Nexus 7 comes in different models for different years. You need to install the factory image below on the 2012 WiFi version only. Each different year will come with a unique file.
  • Do not try installing the file below on any other device or you risk bricking. When that happens, you’ll need to find another un-brick guide to help, usually found over at XDA Developers.

BEFORE WE BEGIN

  • Download the USB Drivers for your Nexus device from our page here.
  • You will lose the root access on your tablet if you are rolling with the system internal unlocked before installing the image below. However, there’s a rooting method available for you already we’ll be posting soon using SuperSU. That means you can flash this stock image and gain root access again without any dramas.
  • You do not void any warranty by flashing official stock factory images so if you have any issues you can seek free assistance.
  • Any custom recovery you may have on the device is going to be wiped along with the root access being revoked.
  • Users with a custom ROM installed looking to return to stock firmware will have to perform a factory reset during the guide. There’s no way out of that.
  • Ensure you have enough battery power left on the tablet before starting the steps so it doesn’t shut down before the flashing finishes. There’s nearly a GB of goodies coming your way so charge accordingly.
  • You need to have ADB and fastboot setup on your Windows computer before starting the guide. Do that with Android SDK here.
