The Google Nexus 7 is arguably the best tablet in the Mountain View companies range. It isn’t bad when comparing it against just about anything that runs Android because it’s always at the top of the list when it comes to Google software updates. We are now seeing the first batch of Android 5.1 OTA updates rolling out for the Nexus 7 with the build number LMY47D. If you are running that firmware build already you can follow the guide below to open up the system internals with root access. Only then can you start installing custom ROMs.
- You need to have the Nexus 7 device to use the guide. Do not try flashing the files we have below on a different device because it may soft-brick the tablet or phone.
- You should already be running the latest version of Android 5.1 Lollipop with the firmware build number LMY47D before starting the guide. Check the build number by looking at the About Device menu.
BEFORE WE BEGIN
- Install the Google Nexus USB drivers on your computer. Turn off the computer and turn it back on again to have the drivers working properly.
- You are installing the official ClockworkMod recovery during the steps. If you don’t want to do that you can skip the CWM file and just flash the SuperSU.
- We advise people backup the OS and ROM using a third-party application from the Google Play Store or use the built-in backup utility.
- The following does the void the warranty if you follow it through. You must flash the official stock Android firmware file back on the device and unroot before the warranty works again.
