How to Unroot the Nexus 10
In case you’ve messed up with your Google Nexus 10 and want to return to stock, you can simply flash the stock firmware. The stock firmware takes your device back to the factory state and wipes off all the data on the device. It removes the Superuser app as well to unroot the device. So, if you’re ready to flash stock firmware on your Nexus 10, just follow our guide below.
I. Before You Begin:
1. You should have rooted your device using the procedure given here.
2. The device should have at least 70% of battery life left as the procedure will take some good time to finish.
