Do note that this is not the only root guide available for your Sony Xperia Z; therefore, if this isn’t on your taste, use our previous tutorials and use the root solution that you prefer the most. Anyhow, either way, before starting to root your Xperia Z C660, C6602 or C6603, read the guidelines from below. This guide is not official so you should consider the same risky and complex – for avoiding the unpleasant situations stick to the steps from below and don’t perform things by yourselves.
The first thing to know when trying to gain root access is the warranty aspect: always, when rooting the warranty gets void. This is happening because root access isn’t granted by Sony or by the carrier from where you bought your device. Actually, the handset is being delivered with carrier and default restrictions that are preventing you from root. But thanks to third party devs, the root access can be granted anyway. So, the warranty will get void; luckily for you, the same can also be restored. All you will have to do will be to relock the system of your handset by re-flashing the factory restrictions. But, how? Well, quite easy: just downgrade your Xperia Z to stock Android OS, or update with an OTA update released by Sony.
As mentioned, root means gaining access to your phone’s internal system. So, gain root access if you want to customize your device and its performances. Basically, on a rooted system you can remove in built programs, you can add new features, you can install custom and complex apps, you can update with a custom ROM, you can flash a custom kernel, you can overclock the CPU and you can upgrade the battery life. Therefore, the root access is the first step to make when trying to tweak your Sony Xperia Z.
In order to conclude, here is what you should know so far:
- Root is not official, so the warranty of your Xperia Z will get void.
