    Failed to root Samsung Galaxy Tab 2 7.0 after android upgradation

    Hello everyone! I recently bought a Samsung Galaxy Tab 2 7.0 which had the android version 4.0 Ice Cream Sandwich.I've just updated my Galaxy Tab 2 7.0 to Jelly Bean and I've noticed a significant decrease in battery life. My tab is not rooted.If anyone can help me out I'd really appreciate it.
