Unrooting the Huawei Ascend G300 is most commonly done to restore the phone’s warranty. When we get root access to the internal system and unchain the internal hardware from the OEM restrictions, we also take away the warranty. Not everyone has a warranty in the first place, so it doesn’t matter to many. With that said, if you did pay for a warranty, it’s something you need to consider. The great news is that no matter what you did to the Huawei Ascend G300, by unrooting it, you can restore the warranty so it works again. It doesn’t matter what rooting method you chose, or how long the device is rooted for, the warranty will start working again just the same.
