Galaxy Tab 2 7.0 users recently received a new OTA update via Android 4.2.2 XXDMH1 Jelly Bean firmware from Samsung. Those who have already updated their tablets with latest Android 4.2.2 firmware may root their devices via CF-Auto-Root tool by XDA Developers Chainfire, using our tutorial below.

CF-Auto-Root tool allows users to easily root their Galaxy Tab 2 on any firmware, as it is firmware independent. It fully supports Android 4.2.2 Jelly Bean as well as future upgrades.

Head over to the CF-Auto-Root developer source page to learn more about the root method used in the tutorial.

NOTE: Rooting the device increases its binary flash counter. The flash counter in turn tracks how many custom firmwares have been installed, as this voids warranty. However, Triangle Away app can be used to reset the flash counter and restore factory warranty after installing CF-Auto-Root.
