My Friend Brought Me His Iphone, Week 48, With The Message Repair Need Contact Apple , So I Ask Him What He Did.
He Downgrade From 1.1.2 Otb To 1.02 Jailbreak And Install Ocktoprep Amoung Other Things, Try Anysim, Didnt Work Of Course, Then Upgrade To 1.1.1 And Accidently, Run 1.1.2 Jailbreak On 1.1.1, When It Was Stuck On Whriting Image Step He Unpluged The Usb And The Phone Start Normally On Springboard , He Proceded To Go To On Safari Because He Didnt Have Installer On Springboard, Dont Ask Me Why, And He Install Installer, But The Baseband From There It Was Corrupted Alredy. Please This May Help Somehow, Since I Thougth There Was No Way To Corrupt Baseband On A 4.6 B.l.
Other Thing I Try To Restore To 1.0.2 1.1.2 1.0.1 1.1.1 And Always Corrupt Baseband, So Finally I Try 1.1.3 And Fix It But Now Itis Stuck On 1.1.3 Baseband With 4.6 B.l
