Rooting the Sony Xperia Z with the Towelroot application is granting your internal system the most powerful kind of root access for the best device modification possibilities. Once yo uroot the device with the Towelroot app, you can go on to install a custom recovery and then a custom ROM. You may also choose to do nothing but install the root-requiring apps from the Google Play Store.

The only things with Towelroot you need to know is that it doesn’t automatically give your device the SuperSU app. The SuperSU app is the app that grants permissions to the rooting app. It’s also handy for giving your device extra protection. When we have access to the root file system, we normally make it easier for malware to access other apps data. However, the SuperSU app stops any malware apps from getting its hands on data and therefore your device is just as safe as it was without the root access.
