How to root Samsung Galaxy Tab 2 7.0 GT-P3100 on Android 4.0.3 [Guide]

Samsung Galaxy Tab 2 These are the guidelines to root Samsung Galaxy Tab 2 7.0 GT-P3100 running on the Android 4.0.4 software update using the CF-Auto-Root tool and the Odin flashing tool from a computer running Windows operating systems.

We recommend waiting for a few days if your device has recently received a new software update available over the air. Sometimes new software updates can bring in new bootloader and when that happens Chainfire needs to update the files for them to work.


  • You must have a Windows computer to use this guide otherwise you cannot get the flashing tool to run.
  • You must have the Samsung Galaxy Tab 2 7.0 with the model number GT-P3100 to use this guide without bricking your device.
  • The CF-Auto-Root tool in this guide is base on the Android 4.0.3 software update with the build ID IML74K.P3100XWALD2. You can not need to be running that same IML74K.P3100XWALD2 firmware. It is to be used as a guide only. Some of the devices Samsung bring out do not boot older images.


  • Download the Samsung USB Drivers for your Samsung Galaxy Tab 2 7.0 tablet and install them on the computer running Windows. You need to get that done before you start the guide so all devices and programs can talk with one another.


  1. Download the updated CF-Auto-Root file for your Galaxy Tab 2 7.0 from this link.
  2. Download the Odin flashing tool for your Tab 2 7.0 from this link.
  3. Extract both the files on the desktop of the computer by pointing to right click > extract here.
  4. Double-click over the executable that says Odin and the flash tool will run on the computer.
  5. Long-press the Power button on your Samsung Galaxy Tab 2 7.0 and reboot it in download mode.
  6. Connect the Samsung Galaxy Tab 2 to the computer with the USB cable.
  7. Click the PDA/AP button from the Odin user-interface and browse the desktop for the CF-Auto-Root-espressorf-espressorfxx-gtp3100.tar.md5 file.
  8. Do not many any adjustments to the default settings available from the Odin flashing tool’s user-interface.
  9. Click the Start button and Odin will now flash that tar.md5 rooting exploit on your Samsung Galaxy tab 2 device and equip it with the SuperSU it needs.
  10. Look at your Tab’s display in a few minutes and wait until it says the device is going to reboot in 10 seconds.

Any device that does not reboot to recovery mode must get it done manually. The vast majority of devices will do it automatically, but on the odd chance your doesn’t, press the Volume Up + Power + Home buttons when booting it up to reach the recovery mode.
