Problems downgrading from OS 4.0 Beta 1 to 3.1.3
Hi,
I am trying to downgrade my iPhone 3GS from OS 4.0 Beta 1 back to OS 3.1.3 using iRecovery/libUSB on windows 7 64-bit. I have the 3.1.3 firmware and I attempted to restore, but I got an error message (it was like error #13 or something, said it was an unknown error but the guides all said I'd get like error #1015 or something like that, though that might've been for mac). And then when I try to run iRecovery, it doesn't detect my iPhone.
The first time I installed libUSB-Win32 I didn't use compatibility mode, but I uninstalled it and reinstalled using Windows XP SP 2 in compatibility mode and running as administrator. I tried closing and re-opening iTunes
other information:
-I have the latest version of iTunes, just updated before trying this.
-I used "libUSB-win32" the latest version, and it installed to Program Files (x86), I'm wondering if there's a 64-bit version or anything?
I can't think of anything else, I'm basically stuck in recovery mode right now, starting to freak out a little bit.
If anyone can help me, I will be extremely grateful!
Thank you in advance!
