Dorlese_D,

I've had the same problem as juanjodg1 and I couldn't find a solution on the link you posted.

I've bought an unlockedd AT&T I777 S2 one year ago and I've been using it with my carrier in Brazil since then without any problems.

But since I've done the 4.0.4 update I keep getting the SIM network locked error.

Can you please help me ?
