Win 7 64bit
.NET 4 installed
UAC off (otherwise right-click and run as admin for all programs)
iTunes 9.2
iPhone 3G (4.0FW)
Firmware downloads – http://www.iclarified.com/entry/index.php?enid=750

Open iTunes with iPhone connected in recovery mode. Click OK/Check. Hold down the shift key and click Restore. Navigate to and select the chosen firmware (I used 3.1.3 3G). Click OK. After a few minutes, ERROR **** (don’t worry)

LibUSB-Win32 – http://sourceforge.net/projects/libusb-win32/files/libusb-win32-releases/1.2.2.0/libusb-win32-bin-1.2.2.0.zip/download?use_mirror=netcologne
Create a folder on your desktop. Run inf-wizard.exe from the bin folder with iPhone connected and turned on. Click next, select your iPhone from the list, click next. Save to the folder located on the desktop.
Open this folder and run installer_x64.exe. Other than the brief appearance of a CMD window there is no evidence of successful install but windows beeped to let me know a device had been connected and the screen lit back up (driver refresh for iPhone).

Open a CMD window and paste this“Copy C:\Program files (x86)\Common Files\Apple\Mobile Device Support\
iTunesMobileDevice.dll C:\Program files\Common Files\Apple\Mobile Device Support\” (without quotes)

RecBoot 1.3 – http://www.mediafire.com/?x2xkfrlz7ibjleb (same link as original poster/author)
Run RecBoot.exe. On my system RecBoot still reported ‘no device in recovery mode found’. Click exit recovery mode. iPhone automatically disconnects/reconnects. My iPhone came back on in recovery mode and just as I was rerunning installer_x64.exe the phone switched to normal mode. :)

I’ve rebooted the phone a few times and installed a couple of apps to make sure everything is working. No problems so far.
