We at Ausdroid have occasionally experienced this kind of remorse, and no, you dirty people out there, we’re not talking about regretting our Saturday night exploits. Rather, we’re talking about what happens if you’ve modified your phone and all of a sudden you need to rely on that precious warranty to get it fixed.
If you’ve rooted your phone, there is a possibility that this will be blamed for whatever’s gone wrong, and so if you are thinking of calling in a warranty service, you might want to consider this. Unrooting can be done by hand, and some of the rooting apps (e.g. SuperSU) can uninstall themselves, but if you’re a bit uncertain and you want to be sure that your rooted handset is returned to it’s unrooted state, then this app might be for you.
It’s called Universal Unroot, and it claims to be 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.
Of course, the flipside of this is that it’s not a temporary unroot; if you want to root your handset again, you’ll need to start from scratch like you did the first time around.
It currently supports all of the major superuser apps, including ChainsDD Superuser, Chainfire SuperSu, and Koush Superuser.
