My phone is 1.1.2 OTB. I accidentally run downgrade baseband package from Installer. I tried to cancel it by power it down. Now when I restore to fw 1.1.1 and iBrick to reboot it I can't use the dial pad to call *#307#. Itune 7.5 keeps saying I need to put the SIM card in even though I have the ATT SIM card in the phone.
What do I need to do to restore it back to 1.1.2 OTB firmware?
