Error 9 after upgrade 4.3.4 or 4.3.5
Folks,
I accepted to upgrade to 4.3.4. After that I got recovery mode on endless loop.
Any help? tks!
iPhone 4, Windows 7
Error 9: This error occurs when the device unexpectedly drops off the USB bus and communication stops. This can occur if the device is manually disconnected during the restore process. This issue can be resolved by performing USB isolation troubleshooting, using a different USB dock-connector cable, trying another USB port, restoring on another computer, or by eliminating conflicts from third-party security software.
In other words:
Use a USB port directly on the computer, not a hub. If it's a desktop use a port on the back, not the front.
Temporarily disable your antivirus and firewall.
