Trying my luck here since nobody at the ifans forums were able to help me. My iPhone 4 is currently stuck on the Apple boot logo due to a Tethered Jailbreak. Thing is, when I put my device on DFU or recovery mode, my computer recognizes it as an Unknown Device http://i.imgur.com/Vu7kL.png The problem is that, being recognized as such, I can't use "Just boot tethered option" or able to restore with iTunes since the phone isn't recognized. I have tried to manually add the driver to "Unknown Device" pointing it to --- C > Program Files > Common Files > Apple > Mobile Device Support > Drivers > usbaapl64. This is what I get http://i.imgur.com/x4yuz.png I've also tried uninstalling iTunes and using REGEDIT to delete anthing iTunes related. That didn't work. I've also tried deleting all USB hubs and let windows re-install them, that didn't work.
