So I fully bricked my fat 3.52 m33-4 trying to put in a xmb. Wouldn't go to recovery at all... So i took it to a guy and asked him to Pandora it.And it looked like he did but instead of going all the way down to 1.5 he went straight to 3.71 m33-2. Now it will go to the Recovery no problem. But when you exit you get the regular boot up the sony logo and tones, But as soon as the time date wave and background come on it freezes. The guy said he didn't know what to do with it that it might have dirty keys? WTF is wrong any ideas or suggestions would be helpful.
