I have a S2 from AT&T (not rooted).
I just did the update some minutes ago via Kies, and now my cellphone is locked.
It's asking me for a "Network Lock Control Key".
I had already updated my cellphone using Kies in the past, and it did not lock it. What can be the problem? How can I solve it?
And I'm not living in the US right now, so I cant take it to the vendor to re-unlock it!
any help will be appreciated
