Thanks to Wugfresh over at XDA, Galaxy Nexus users now have an even easier way to relock their bootloaders and restore their device back to stock, out of box state, with a neat little program. So, if you need to send your Nexus in for warranty reasons or just feel like starting over, here’s how.

I. Before You Begin

1. This will erase all data on your device so please make sure to back everything up before beginning.

2. This program only works for Windows.

3. During this procedure, we will assume you did our How To Root the Samsung Galaxy Nexus (One Click Method) (LTE and GSM Versions) and have the proper drivers installed as well as this program already available. If you didn’t use the procedure to root, don’t worry, this WILL still work for you but you may have to refer to the rooting procedure to get drivers installed etc then come back to this to continue.

II. Unroot the Galaxy Nexus

1. On your phone, make sure USB debugging is turned ON under Settings > Developer Options.2. Plug your phone in via USB cable.3. Open the Galaxy Nexus Toolkit that should still be on your computer from the How To Root procedure. If you don’t have it, head to that procedure to download it from there, do the setup the drivers steps if necessary and then continue with this procedure.4. Click on Flash Stock + Unroot and follow the prompts.5. Once done, click on OEM Lock and wait for the phone to prompt you, click Yes and wait for it to reboot.

6. All done!
