I upgraded to 4.0 and now im trying to downgrade back to 3.1.3. I have 3.1.3 installed but it wont come out of recovery. I have tried it all and cant get it out of recovery. Im running windows 7 64 bit. I tried iRecovery, Recboot and nothing. I followed all the steps to the T and been trying for almost 4 hours. Someone please take me out of my misery and spoonfeed me this stuff....PLEASE...lol
