    I bought an iPhone 3G off of a friend, that was never before jailbroken or anything. He updated it to 4.0 right before he gave it to me. I've been trying for 8 hours now to downgrade it from 4.0 to 3.1.3. I've gone through every tutorial you could name and everything.

    I am running Windows 7. I installed libusb in XP SP2 compatibility mode, run as an administrator. In iRecovery I'm getting the "Got Usb. No iPod/iPhone Found" error.

    I have tried everything. I cannot get it to work.

    Can anyone give me a tip here? I hate iOS 4 and I want to go to 3.1.3.

    OH, and I DO NOT have an SHSH backup or anything like that.

    Sorry if there is a lot of information missing that's needed, just ask. I've been here in this chair for 8 straight hours, skipping out on sleep =/

    All you have to do is stick it in DFU mode and shift + restore to a 3.1.3 firmware

    But I get the 1015 error at the end of the update, and it's stuck in restore mode.

    afaik you cant downgrade to 3.1.3 because apple doesnt sign the firmware anymore. there have been several tricks to do but none of them work (i tested them).

    but you can still downgrade to 3.1.2 without ANY problems. i wanted to restore to 3.1.3 too but then i had to choose 3.1.2. (difference wasnt so big)

    go for 3.1.2

    I tried downgrading my 3g iphone to 3.1.2 yesterday and also got the 1015 error? Took me 8 hours just to get it back to OS4 (exactly what i started with). Ended up Stuck in recovery mode and itunes wouldnt recognise my iphone. Didnt try iRecovery, but iReb did nothing.

    Wow, I can't even jailbreak 4.0. I downloaded the 4.0 software for my 3G, and it would just exit iTunes mid way through the restore.
