4.3 Jelly Bean

What Is Rooting the Android Operating System?

When you buy a new smartphone, you might not know it, but the Android operating system is in a “locked” state. For the most part, it will not make much difference to you: most apps are still available to use, and there are benefits to this locked state such as better security. When you root the Android operating system, you are gaining full administrative rights over the OS.

Why Would You Want to Root Android?

Gaining full administrative rights over the operating system has some perks to some people. For example, out of the millions of applications available on Google Play, some of them will not be able to run on your device unless it has root access. Until you have a specific need for wanting Android rooted, you probably want to leave Android as it comes out of the box. But if you need to unlock an app, then that is when you want to look into rooting methods. Using more apps is only one example of why you may want root access, here is the full list of benefits:

  • Unlock more applications. Some of the apps available for Android cannot run unless you have root access. This is because the app’s features cannot run without the root permissions because the features require the full system access before they can be useful.
  • Better battery life. Smartphones are great, but they have one caveat, which is each time you recharge the battery, it loses some of its overall lifespan. That means smartphones, in general, do not make great investments, and if your weekly paycheck is low, you will want to limit the number of smartphones you go through. One of the ways you can do that is by removing bloatware and creating a better battery life.
  • Bolster performance. If you are the budget-conscious shopper, you may want to increase the device’s performance. This can be done by removing the bloatware as well. The more processes you have running, the more memory that is used. By removing some of the apps, it can help lighten the load on your hardware.
  • Customize Android with themes. With root access, you can download and install any theme that’s at your disposal. That includes any customized theme you can find.

What Are the Risks of Rooting?

If you are buying a smartphone that is not running iOS, then it is probably the Android operating system that you want running as the ideal software to pair with your shiny new hardware. It is, in fact, the Android OS that offers you the chance to customize the OS considerably more than iOS: custom themes, run any app you know about, the works. For many users, the “openness” of an operating system is important, because it offers them more freedom which means running into fewer problems with their investments. But there is a reason iOS likes a far more locked approach: the ability to customize is not for everyone, and if you do not know what you are doing it can lead to a lot of problems which can define your time with the OS rather than freedom.

With power (full admin permissions) comes greater responsibility. Here are some of the main risk factors when it comes to rooting:

  • Malware becomes a larger threat. You might read the occasional news article about how new malware is wreaking havoc in parts of the world on Android. But the Android operating system with root access becomes considerably more vulnerable to exploits because applications are no longer prisoned off in their own sandbox environments. This means if you accidentally download malware, it can do more damage because it can spread throughout the operating system and even jump into other applications and potentially view sensitive data.
  • You can accidentally brick the smartphone. There is always a chance that you end up bricking the smartphone before you had the opportunity to use it with root access. That is because if you are going to brick it, it is going to happen during the rooting process.
  • You may void the warranty. Most manufacturers do not allow you to root the Android operating system and still get to bring it in for repairs under warranty. Whether they are legally meant to do that or not is another question, but it is now common knowledge that most do not want to help you if they find out you have unlocked the OS with root access.

Details of Note

  • Download and install applications available from the Google Play Store such as Helium to aid you with backing up the data. Rooting generally wipes the data from the ROM. However, you can back up the phone contacts, videos, pictures, EFS folder and all other data you want to keep to the devices internal storage memory. The memory does not get wiped. You can use the external SD card if you prefer but it’s not necessary. Those with the internal system unchained from the default factory restrictions already will prefer taking a Nandroid backup and using apps such as titanium. You can use other such as SMS backup+ to help you make copies of the text messages you wish to keep.
  • The antivirus, spyware protection and malware protection can interfere with proceedings. That’s why we recommend you temporarily disable them until you start browsing the web again. there is no virus inside any of the files we are presenting in this guide.
  • Make sure you enable USB Debugging mode. Some devices running Android 4.2 have this menu hidden and it requires you to tap on the build number seven times. However, since we know you are running 4.3, the menu isn’t hidden. You can anytime access is from the settings menu. Click the Developer Options menu and enable USB Debugging mode inside.
  • Use the guide only if you have the Sony Xperia Z handset. Don’t attempt to install the files on any other device, as you will soft-brick or hard-brick the mobile. Moreover, make sure you have the latest USB Drivers installed. Transferring from the computer to the smartphone SD card or internal memory is the safest way to use files. You must have the drivers to connect to the PC. Most of you have them already. If you are connecting to the computer and can get access to the data from the phone, you know it’s working.
