While most people aren’t as interested in unrooting phones opposed to rooting them, there’s still the occasional need. For instance, many like to sell a device unrooted or may need to submit an insurance claim and want to make sure their carrier doesn’t try to use its status as a rooted device as an excuse. I can only think back to the time where a T-Mobile rep blamed my cracked G1 display on the fact that my device was rooted, thus allowing them to refuse to honor my insurance and warranty.
Welp, if you’ve ever found the need to unroot your device, developer Matt Groff — creator of the Batakang ROM — has a very useful utility that you’ll want to check out. It’s called Universal Unroot, and it’s apparently able to unroot any rooted device from any manufacturer regardless of which version of Android it has. It will not only remove any superuser app you have installed, but will completely undo the exploit at the system level, meaning it’s not simply a placebo effect.
It costs $.99 in the Google Play Store, which isn’t much in the grand scheme of things. It’s an app you might only use once or twice in the next few years, and the manual unroot process is typically fairly easy, but it’s not unreasonable to have to pay for convenience. The app claims to support any device based on x86, ARM, and MIPS architectures, which account for nearly all Android devices.
It will also support all of the usual suspects in the superuser app game, namely ChainsDD Superuser, Chainfire SuperSu, and Koush Superuser. Note that the app won’t re-root your device, so be sure you want to unroot before doing it, and prepare to use the appropriate root methods if you find the need to reverse the action. Find it for download in the Google Play Store.
