The Galaxy Tab 2 10.1 P5110 recently received a firmware update which brought many new features. However, to install ROMs, apps, and other tweaks that are not available on the official Google Play Store, you need to root the device. Thanks to Chainfire, member of XDA Developers, it is now possible to root the tablet.
The tool released for this purpose is the famous CF-Auto-Root. This makes rooting a breeze and it’s ideal for those who are new to the customization scene. However, please note that rooting will void the device warranty. Keep in mind, however, that it can be uprooted if necessary.
Before moving on to the tutorial itself, there are a few prerequisites that you should know. First of all, the tablet model with which this guide is compatible is P5110. Using the steps on other models may permanently damage them. You should charge the battery to a significant percentage level to prevent the device from turning off during the process. It has been reported that security software prevents installation of some files, so it is wise to disable them on your computer. Make sure the handset USB drivers for the device are already installed and you are on a Windows PC. It is always recommended to create a backup of important files before attempting such procedures. Finally, follow each step as you wish, as we will not pay any damage or take any responsibility if the device is damaged.
To guide
Step 1: Download the CF-Auto-Root package.
2nd step: Extract the contents of the package to any preferred folder on the computer.
Step 3: Launch the Odin ‘.exe’ file from the folder where you extracted the contents in the previous step.
Step 4: Restart the device and hold the right volume up button as well as the power button until a yellow sign appears, and when it does, press the left volume down button to enter download mode.
Step 5: Once you enter this mode, connect the tablet to the computer using a USB cable. Odin will display an ‘ADDED’ message and ID: COM will be yellow. This means that the device was detected successfully, and if no such message is displayed, reinstall the drivers.
Step 6: Press the “PDA” button in Odin and locate the CF-Auto-Root “tar.md5” file where you extracted it. Leave everything else unchanged in Odin and also make sure the Re-partition box is unchecked.
Step 7: Now go to the ‘Start’ button, which will lead to the installation. When finished, a ‘PASS’ message will be displayed after restarting the tablet. If the software freezes or displays a FAIL message, remove the back cover, remove the battery and replace it. Now install the firmware and follow the steps from step 4 where you entered download mode.
If the PASS message was displayed, your Galaxy Tab 2 10.1 P5110 was rooted. Enjoy!
