Just connect phone to a computer/tv or any USB device except charger, power off device, then press vol up+power button, release when you see samsung galaxy boot logo, you'll go to stock recovery if you followed instructions correctly. Then use the vol down button to select wipe cache. Then press yes when prompted, it will auto goto reboot system now. Press ok and then you should be back in os.
