listen to rza. downgrading is extremely risky. Bricking is NOT good! If i were u, I would wait to the CFW for 3.56 is released. If u read something on our forums or another websites forums about a 3.56 CFW, don't automatically believe it. Wait till you see confirmations by other members of the website in which you are viewing. When the time comes and the server floods for NGU like it did in early January when the 3.55 CFW was released, you know that either the 3.56 CFW was finally released and verified or other big news is occuring, like the Black Ops 15th prestige hack. Since it seemed like you just joined, I have acouple warnings for you:
One: You can get scammed by other players here. Its not approved on the site but it has happened.
Two: When you download something from the site, makes sure, you use a virus scanning program to make sure its not encoded with trojans.
But otherwise, welcome to NextGenUpdate! We are glad to have you in our online gaming and hacking community. Pm me if you have questions. Have fun!
