Is the latest iOS 5.3(6105) supported by Seas0n Pass Jailbreak?

I had my Apple TV Gen 2 all good an jailbroken with ATV working until I saw the newest software version, I went on and updated my Apple TV but I wanted to have the new ESPN and other channels in it.

After that I’ve tried both types of jailbreak and nothing seems to be working, am I doing something wrong or is this a problem because of my 5.3 upgreade before jailbreak?
