How To Unroot Nexus 4 Without Losing Data

Rooting is one of the things that makes Android so much better than other mobile platforms. From installing battery saving and performance improvement apps that require root access to flashing mods and cool custom ROMs, you can do a lot more on your phone after rooting it.

While rooting definitely opens up many possibilities, it is not for everyone and some of you might be interested in unrooting your Nexus 4. Manufacturers also reject warranty claims if the phone has been rooted or if there’s a custom firmware installed.

In this guide, I’ll show you how to unroot Nexus 4 on Mac and on Windows. Through the methods mentioned below, you’ll have an unrooted Nexus 4 in just several minutes.

  1. Hi there, this doesn’t seem to work for me on my nexus 4 on my mac. Downloaded the zip, connected phone etc, on Step 3 when typing “./fastboot-mac flash bootloader bootloader-mako-makoz10l.img” into Terminal – it tells me “./fastboot-mac: No such file or directory”

    Zip folder has been extracted.

    Are you able to please help?!
