    please help!

    I've got a iphone 3g and stupidly updated to 4.0, i'm trying to downgrade to 3.1.3

    I have downloaded the 3.1.3 firmware and then put phone into DFU mode the done shift+restore in itunes, it runs the restore of 3.1.3 and then as its about to finish i get the above error.

    What do i do????

    The error is expected (itunes tries to downgrade the baseband but cant). All you have to do is kick it out of recovery. There are a number of tools that do this. Google Recboot, it is a good one. If using vista or windows 7 make sure you use compatibility mode and pick xp when installing libusb (required for recboot to work). Also if you are vista 64bit be very careful with libusb, you have to install it a certain way or your usb devices may stop working. Other tools that do this are irecovery, ireb, error1015 fixer and even an old version of quickpwn will work.

    i have downloaded recboot and libusb, i cant see how to install libusb though and the recboot keeps failing coz libusb isnt installed, can you help? after 2 days of this my brain is fried!

    ok, i've managed to install libusb now but when i go into recboot and click exit recovery mode nothing happens, any ideas?

    Google "download quickpwn 2.2" open it with your iphone connected and it will give instructions to hold power and home button for 15 seconds. Do what it says and it should kick you out of recovery.
