Google's first tablet Nexus 7 is for a few days available in retail, one or the other reader calls it certainly his own. For those who have the options of Jelly Bean already fully explored and skills of their tablets now want to expand by root access, we introduce two suitable guides available.
Root: Full access to the system
Root called on Unix-based operating systems, to which also belongs Android, both the root node of the file structure ( "/") and those user who has full access to all of this outgoing files. It corresponds to the Windows world about an account with administrator privileges. to gain on the smartphone or tablet root access, the user to access not only to shared places such as the internal or external memory card, but can also alter system files allowed. This is for example necessary to make backups of installed programs and play back, but also to replace the entire system via CustomROM a new one. This is made possible by the manufacturer's own recovery system is replaced by a third party, such as the ClockworkMod recovery. About this the user can install firmware packages on the system partition ( "flash ROM") that have not been signed by the vendor. Especially when Nexus 7 a gerootetes system has also the advantage to use via Micro USB Adapter mass storage devices such as external hard drives and USB flash drives.
Warning: With great power comes great responsibility
Precisely because the user can write with root privileges on the system partition can be much go wrong - including the unusable device. The routes described here have been tested and proven reliable. Nevertheless, for those who follow our instructions, does so at their own risk. We assume no responsibility for any damage done. By manipulating the system level, the warranty is void. So make sure to read the instructions once completely and makes sure that you know what you are doing.
Below we present two ways to root the Nexus 7th The first is based on a toolkit that was put together by XDA forum member mskip and all required files is conveniently available. During this Toolkit works with Windows only, shows the second way how to rootet the Nexus 7 from Windows, Linux or OSX. However, the procedure is the same both times: First, the bootloader is unlocked, then flashed a custom recovery installed and this one app for managing root privileges. In the course of both procedures, the entire tablet is reset, data contained will be lost.
Option 1: rooting under Windows
The easiest way for Windows users certainly represents the toolkit, which is available in the XDA-Developers forum to download free. After downloading from the first post install you start by double-clicking. During which you will be asked if you want to install the necessary USB driver also what is confirmed, they should not be present. After installing a desktop shortcut to launch the toolkit will be created.
Before you double-click this, you can switch the Nexus 7 from first and boot it down with the key combination Power + Volume in fastboot mode. After the start of the toolkit you choose option 1 to install a device driver, if you have not already done during installation of the toolkit. If the installation goes well, you can check in the Control Panel via the device manager. There is an entry for "Android Debugging" should be visible. Once the tablet is connected to the PC, it should also appear in the header of the tool depending on the mode under fastboot or ADB.
Has so far everything is successful, you connect the tablet in Fastboot mode now using the USB cable to the computer. On the tablet itself should at the very bottom in red &# 8220; Lock State &# 8211; locked&# 8221; be read - that's what we are about to change. The process can, to be sure, execute sequentially on options 3 to 6, which requires a confirmation on the tablet itself, depending on the action. To do this, navigate with the buttons volume up / down, a short press on the Power button to confirm it. After step 6, you have to restart the Nexus 7 (Option 20) and activate the developer options after logging in the settings and put a check mark on USB debugging. The tablet is the whole process through connected to the computer. Selects the completion option 7 to install the tool collection Busybox.
Alternatively, option 8 selects after the tablet has been connected to the PC in fastboot mode and the drivers are installed with Option 1, out. This leads one after the steps described above.
No matter which option you chose, the Nexus 7 should have after a restart on root access. To test whether the action was successful, you can, for example, Titanium Backup, install and run a root app. In her first start the application should ask for permission to obtain root privileges. Voilà!
Option 2: rooting under Windows, Linux and OSX
Who owns or a system with Linux or OSX can not be put on Windows from the command line that loads from the side nexus7root down the same ZIP package. This method has the advantage that really only the files needed to be downloaded. Note: The package includes the tools adb and fastboot for all three operating systems. For the sake of clarity, only the talk of the programs themselves will be in the following, depending on the operating system command but for example by ./fastboot-linux or replace ./adb-mac; Windows file extension must be considered: fastboot.exe.
Unpack the archive first. On Windows drivers must be installed as above, first, that can be found in the corresponding folder of the archive. Just connect the tablet to the computer and waits until it is detected. The automatic installation will fail, so I open the Device Manager in the Control Panel. Here is an entry for "Android" should appear under "Other Devices". By right-clicking on these you choose to manually search for drivers the option. Now navigate to the folder that was extracted from the archive and selected him. Windows should browse the folder and install the appropriate driver properly.
Now open the terminal emulator (Windows "Power Shell") and navigate to the folder where the archive is extracted. Possibly the programs contained on OSX and Linux with chmod 755 * must be made executable. The Nexus 7 has to be separated from the computer, and started off with the key combination Power + Volume Down in the fastboot mode. After the tablet has been reconnected to the computer, you checked back in the Terminal window with the command fastboot devices whether the tablet is detected.
Is below the last command a device number to see the procedure can go on. Since the Nexus 7 comes directly from Google, the boot loader can be unlocked without fuss with the command fastboot oem unlock. now a warning label that briefly explains the consequences of unlocking appear on the tablet. Using the volume rocker to navigate to the corresponding Manüpunkt and accepted with a brief press on the power button. Now the red text should (bottom left "Lock State &# 8211; Unlocked ") show. If one examined by the volume keys the menu item "Reboot" and starts with the power button, the tablet. After signing the developers options to be activated in the settings and tick the USB Debugging be set.
On the computer to copy the CWM-SuperSU-v0.94.zip file to the internal SD Card of the tablet. If the device is not recognized, helps a disconnecting and reconnecting using the USB cable. In particular, Linux prepares the fact that newer Nexus devices no longer distinguish between system and mass storage, still problems. If the Nexus 7 is not as MTP device ( "Media Transfer Protocol") is detected, the file can also be transferred via the command adb push CWM-SuperSU-v0.94.zip / sdcard /.
the archive is located on the SD card, the tablet has again turned and started with the now familiar key combination in the fastboot mode. In the console to type now in command fastboot flash recovery recovery-clockwork-touch-18.104.22.168-grouper.img one in order to install the custom Recovery ClockworkMod. Hereinafter, it deletes any remaining residue with almost boot erase cache.
Using the volume buttons on the tablet "Reboot Recovery" must now be changed and confirmed via the power button for entry. Nexus 7 can now be separated from the cable. Once in recovery, you select one after the points install zip from sdcard, choose zip from sdcard, CWM-SuperSU-v0.94.zip. After a short installation, the device via the corresponding menu item can be restarted. Dialogue to secure the custom recovery and root app should confirm it.
After restarting the SuperSU application is to be seen in the App Drawer. To check if all goes well, you can download, for example, Titanium Backup or the ROM Manager from the Play Store. At the start, the superuser app should open and ask if root privileges have been granted. Congratulations, you got root!
