(adsbygoogle = window.adsbygoogle || []).push({}); So i installed the 4.11 koisk "CFW" firmware and i never went back to the 4.11 official firmware and when i went to play mw3 it said i needed to update , even when i tried to sign in it said that . so i went update and it said 4.20(shop) so i updated it and now it says im in 4.20 demonstration mode . and i cant sign in or do anything . i thought maybe you can go on the us.playstion.com and get the ofw 4.20 but it hasn't even came out . can someone please help me ?

You are going to have to wait until the 4.20 FW comes out on their site and then go into the recovery menu and load the official 4.20 FW. If that doesn't work, then you're gonna bee shit out of luck.

Thanks bro , hopefully it will work .
