I have an iPhone 4S (AT&T) that Ive had for about four months. Not jailbroken or anything, just plain vanilla. This evening I was trying to update to iOS 6.0, using iTunes on a computer running Winbloze 7 starter. The update failed, and iTunes reports an "Unknown Error: 1604." Anybody got any ideas as to WTF happened?

Further info: After the failed update, iTunes reported an iPhone in Restore Mode. Said I had to restore it before I could update, etc. OK... Click restore. iTunes extracts software, time passes, and it presents me with a "Restore Failed" notice.
What to do now?...

OK... Smart phone, dumb biker.
Problem turned out to be that I was using the wrong USB port. iPhone needs a USB 2.0 port, or it wont do an upgrade or restore. I'd been using a USB 1.0 port all along for syncing, and it worked. But it didnt occur to me to check the port types directly.
The bottom line: Wulf outsmarted himself again...

Hi,there.I updated my iPhone to ios6.1.1 several days ago.In general.there''re two ways to make it.First is to update with the iPhone itself.Settings-Common use- Software update.You can directly update here.
The other way is what I suggest.Use iTunes to update your iPhone.Last edited by wwjw.com; 01-09-2013 at 01:10 AM.

when the os does not load and all you get is the logo repeatedly booting:
1 pop out the back plate, and then the screw connecting the battery.
2 just unplug the sensor cable and snap it back in.
make sure the iPhone is connected to a power source (though not pertinent if the battery has enough juice)
