I don't know whether this is definitely the exploit you did or not (though "blade" leads me to believe it's so), but this works for Jelly Bean, both the 98.72.8 (December 24, 2012 leak), and 98.72.16 (the new newly released OTA version, the most current Jelly Bean). You MUST follow the screen prompts and continue through the entire process. Also, even if you have already activated "Battery saver" on Smart Actions, you will still need to go through the motions as instructed.
Here is a link to the Root Exploit Release and Discussion thread.
