I had my iphone 4 with 4.0.1 JB with limera1n. I used Tiny Umbrela to save my blobs SHSH and then went to itunes to update. It got half way through and gave me this error: The iphone could not be restored. An unknown error occurred (1013). I have tried putting phone in DFU mode and no luck! Now my phone just sits here with the usb cable and itunes logo! Please help me.
