The rooting an Android device is often the only way to new updates and features. We show you the principle after the Rooting works on all Android devices like Galaxy S4 Nexus 5, HTC One & Co. and explain all technical terms that you need to know.

The rooting of Android smartphones and tablets is not quite trivial, but also not rocket science. We show below how to do it and what you need to know when rooting. Then you realize the full potential of devices like the Galaxy S4 (mini), the Nexus 5, HTC One, Moto G & Co.
But why should you rooten your Android phone or tablet? Imagine this: You want to import on your PC the current Windows . But that is not because there is no approved by the manufacturer of the PC version of the Microsoft operating system. Also, your programs complain again and again about the fact that the PC is denied access to some functions and party does not make useful information. An absurdity, or

For Android devices, this is exactly the case. The system partition can not be described with new data and apps can not be run as administrator. The fact that many users have become accustomed to, but does not mean that you could not change that. By rooten your Android smartphone or tablet, you get the absolute rule back on your device. “Root” is the way, the administrator of the Linux world, from which also comes Android.
That’s what rooting
Just about every Android device can rooten. Concretely rooten: pry the write protect the drive (more precisely: the under / system partition mounted). From where the manufacturer has installed the Android operating system

Then install the program su With his help can download apps to gain admin rights and so have access to all functions and information on your mobile device. A similar function is also available on Windows. There she is, “Run as Administrator”.
benefits of Rootens
By rooting suddenly work all the interesting apps that are marked “Only root”, “root only” etc in the app stores from Google Play and Amazon as well. That alone is worth it in our opinion, worth the trip.
You can remove pre-installed junk, create a full backup of the device, the CPU underclock (saves electricity) or overclock (brings more speed), the switching on and off of mobile data reception, Wi-Fi, GPS and Bluetooth automate and much more.
coronation : For many long-abandoned by the manufacturer devices can be found on the net current versions of Android, known as custom ROMs. The but you can only install with root access.
Any existing SIM lock is not canceled by the rooting way. But the root account can be the basis for it.
Different Rooting Methods
Ultimately it is by root always to get a write access to the / system partition and install su . The way there differs from device to device. Therefore, we can give you a universal guide. But we will outline the available methods.

step by step
helps you understand that you will find for example the numerous instructions, if the web for the name of your Android device, connected to the word “rooten” or “rooting” search.
rooting via app
Some devices can be personalized with so-called “one-click tools” rooten. These are apps that you install as usual under Android, start, then click on “rooting” and you’re done. One-click tools based on the fact that resourceful developers discover vulnerabilities be played by the manufacturer Android, through which they can gain write access to the / system partition. These vulnerabilities are but increasingly rare.
Assisted rooting
For some devices there are Windows programs that take care of all tasks related to rooting and flashing , such as the Nexus Root Toolkit. This will guide you step by step through the installation of the necessary tools and drivers as well as the actual rooting.

order for these tools work, turn off first the developer features free on your smartphone or tablet. This is done in the settings under “About Phone” (may vary by manufacturer slightly different hot). There you tap seven times in a row on the build number. You then go to “Settings> Developer Options” and enable USB debugging. Then connect the device via USB to the PC.
To activate the USB debugging, you must first enable the Developer functions.
rooting on foot
Windows tools known to us are ultimately pretty interfaces for the command line program Android Debug Bridge, short ADB. With this program you can access from your computer via USB to any Android mobile device with USB debugging turned on and call functions. Is there not a one-click tool or a Windows tool for your device, then you are hardly around the use of ADB.
The ADB is part of Google’s developer software, the Android Software Developers Kit (SDK). In many cases, this large downloads but installation can handle.
On Windows, you first install the UniversalAdbDriver, which supports most Android Phones . You will also need the JavaSDK and minimum ADB and fastboot. For OSX and Linux ADB extends Fast Boot Install.
few devices you can remove the write protection for the / system partition with the help of ADB readily. For this purpose the system property ro.secure must be set to 0 or ready to 0. You can then mount the read only suspended / system partition for reading and writing. This is rather exotic – just that you’ve heard it before, this possibility should be described in a manual for your device
.
From Bootlaodern, recoveries and ROMs
If none of the options described so far works, you have to go a little deeper. The following Android background knowledge about losing this much easier.
When you turn on your smartphone or tablet, start the first of the so-called Bootloader . This software loads the Android operating system, or – if you hold a specific key combination during startup pressed – the recovery. The recovery (to German: Recovery) is a tiny operating system Android updates (“ROM”) installed
.

Are bootloader and recovery not protected from encroachment (“unlocked”, ie unlocked), the rooting is easy. To download from the web a custom ROM (ie, a modified Android) down. It has to fit your device, and of course included below.
custom ROM you transfer to your device. Then start the recovery mode a to press at startup key combination and install (technical term: “flash”) the ROM.

Of course, most manufacturers
protect their devices against such interventions. Then you need to unlocking the bootloader. Particularly easy thanks to Google’s Nexus devices , but also for many other smartphones and tablets are appropriate hacks available.
this kind of preparation can be a custom recovery to flash, such as the widespread ClockworkModRecovery. It allows the installation of custom ROMs, which of course contains su. With the standard recovery of the manufacturer that is impossible.
Android: Tips for Safety & Professional settings
The boot loader starts either Android or recovery mode. With a custom recovery like ClockworkMod Recovery you can install custom ROMs on your mobile device.
What else is important
Custom ROMs are usually distributed as ZIP file . Either download the file directly with Android down or transfer them from your PC out there, for example by AirDroid. In ClockworkMod Recovery go to “Install ZIP” to install the custom ROM.
By rooting you lose theoretically warranty claims. Practical allows the rooting almost always undo before taking the set for repair. Nevertheless, you should inform yourself before rooting about how you unrooten your device, can make the process so undone.
