WiFi Sync, the application that gives you the possibility to synchronize your terminal via WiFi with iTunes, has a major problem when you have to restore using iTunes. Yesterday while I was trying to do the tutorial this I noticed that when I tried to restore my 3GS, the restore process got stuck somewhere around 60%, it stayed like that for about 5 minutes, after which I got iTunes Error 14 and the phone went back into Recovery Mode.
Unfortunately, I didn't manage to figure out where the problem came from until after several hours of failed attempts to restore, but in the end I realized that Wi-Fi Sync causes problems with the restore process, the result being what I explained above . After uninstalling Wi-Fi Sync and restarting everything returned to normal, I managed to restore normally and go to 4.0 with jailbreak.
I had version 1.0 of Wi-Fi Sync, I don't know if version 1.1 solves the problem, but I warn you to be careful with Wi-Fi Sync, and if you encounter the problem with iTunes Error 14 and you have Wi-Fi Sync installed, then uninstall Wi-Fi Sync and you have a good chance to solve the problem with this.
