http://forum.xda-developers.com – Hi, Yesterday and today I'm trying to unlock my AT&T Note II, first, I tried by this method (bit. ly /YSiR0M), but it didn't worked, so I decided to call AT&T to see if they could give me an unlock code. As I expected, I got it, so when I went to unlock my Note 2 the phone told me "Network unlocked successfully" but kept saying in the notification bar that was blocked and could not call, send messages, nothing. I thought it was software problem, so upgrade to the latest official samsung, but as I suspected, did not work, the message was appearing again in the notification (HowTos)
