What is Android Root? How does it work?
Android Root is the process of allowing users of Android phones, tablets & other devices running the Android Mobile Operating System to attain the privileged control (known as the root access) over various Android subsystems. As Android uses the Linux kernel, rooting an Android device gives the similar access to administrative (superuser) permissions as on the Linux or any other Unix-like operating system such as macOS or FreeBSD.
Rooting is often performed with the goal of overcoming limitations which carriers & hardware manufacturers put on few devices. Thus, rooting gives the ability (or permission) to alter or replace the system applications & settings, run specialized applications (“apps”) that require administrator-level permissions, or perform the other operations which are otherwise inaccessible to a normal Android user. On the Android, rooting can also facilitate the complete removal & replacement of the device’s OS (operating system), usually with a more recent release of its current operating system.
Root access is sometimes compared to the jailbreaking devices which running the Apple iOS operating system. However, these are different concepts: Jailbreaking is the bypass of some types of Apple prohibitions for the end user, including modifying the operating system (enforced by the “locked bootloader”), installing the non-officially approved applications via sideloading, & granting the user elevated the administration-level privileges (rooting). Many vendors such as HTC, Asus, Sony & Google explicitly provide the ability to unlock devices, & even replace the operating system entirely. Similarly, the ability to sideload the applications is typically permissible on Android devices without root permissions. Thus, it is primarily the third aspect of the iOS jailbreaking (giving users administrative privileges) that most directly correlates to Android rooting.
How you can easily root an android device?
Android Rooting is equivalent of jailbreaking, a means of unlocking the operating system so you can install all kind of unapproved apps, update the OS, deleted unwanted bloatware, replace the firmware, overclock (or underclock) the processor, customize anything & so on.
After all, “The Android rooting” around in all your smartphone’s core software might seem like a recipe for disaster. One wrong move & you could end up with the bricked handset.
Thankfully, there is a utility that makes rooting a one-click affair: KingoRoot. It’s free & it works though not with all Android devices.
The App Version
The easiest way to use the KingoRoot is to install the app version, which literally with just one tap performs the root process.
In fact, the only complicated part is the actually getting that app onto your Android device. That’s because it is not available in the Google Play Store; instead, you must download the KingoRoot APK & manually install it.
Ideally, you will just point your device’s mobile to the KingoRoot Android page & download it directly. If that doesn’t work for some reason, or you are working from your PC, download the APK & email it to yourself as an attachment. Then, on your device, open that e-mail & download that attachment.
To install it, however, you will need to make sure your device is set to allow apps from unknown sources. In most versions of Android, that goes like this: Head to the Settings, tap Security, scroll down to Unknown Sources & toggle the switch to the on position.
Now you can install the KingoRoot. Then run the app, tap One Click Root, & cross your fingers. If all goes well, now your device should be rooted within about 60 seconds. (On my aforementioned Galaxy S6, the process made it to 90 %, then the phone crashed & rebooted. Luckily, no harm was done.)
The desktop version
Kingo’s support pages suggested I might have better luck with the Samsung Galaxy S6 if I tried the Windows version of the KingoRoot. Here’s that process:
No adware! Leave this box unchecked & be sure to click Decline during installation.
Step 1: Download & install the KingoRoot for windows, making sure to leave unchecked the option to “Install the Yahoo-powered Chromium browser” & then click Decline to prevent any other adware incursions.
Step 2: Enable the USB debugging mode on your smartphone. If it’s running Android 4.0 or 4.1, tap on Settings, Developer Options, then tick the box for “USB debugging.” (You may need to switch the “Developer options” to on before you can do so.) On Android 4.2, tap on Settings, About Phone, Developer Options, & then tick USB debugging.” Then tap OK to approve the setting change.
On Android 4.3 & later (including 5.0, though this also applies to some versions of 4.2), tap on Settings, About Phone, then scroll down to the Build Number. Tap it seven times continuously, at which point you should see the message, “You are now a developer!”
With that done, tap Settings, About Phone, Developer Options, & then tick USB debugging.” Then tap an OK button to approve the setting change.
Step 3: Run Android Root on Windows, then connect your phone via its USB sync cable. After a moment, the former should show the connection to latter. Your device screen may show the “Allow USB debugging?” pop-up for approval. Now tick on the “Always allow this PC” & the tap OK.
Step 4: Click on Root, then sit back & wait while the utility does its thing. After several minutes, my Galaxy S6 got to 70 %, & then the phone once again crashed & rebooted. Again, your mileage can (& most likely will) vary, & that’s all there is to it. If you decide you want to reverse the process, just run Android Root APK again, connect your phone, then click Remove Root. (Same goes for the app version, less or more.)
