Sorry for weak english

---

Didn't solve my problem

---

thats the same thing as my customer so we are updating iTunes now

---

None of these solutions worked for me. IPhone 4s, Windows 7.

Click "Reset Settings," and the iPhone 5s has blocked me, a black screen with the logo of Appel and a line appearing below.
That I can do to get it working again. I've already tried with the button "Sleep / Wake" button and the "start", pressing them both at once, and nothing, it does not unlock.
Thanks in advance for information.

This bar should indicate the progress of the restoration. If not moving after a reasonable time, connect it to iTunes and try to restore from the computer.

Same problem.  Tried to restore on several different updated Macs with antivirus disabled.  No success.  Then I tried using a different cord and now it's restoring and updating.  I didn't think that could be the problem since it was a new iPhone 6 with the new cord from the box.  Worked for me.

I just used a different sync cable and its worked

Answer 3

I tried several different things to fix error 1671. It finally worked once I switched the USB cord from a generic cord to an Apple one.

Had to run the process 6-7 times for my IPad 2 before it finally did work. A bit of patience is also required I reckon.

I'm glad I found this!! I was using a different brand USB that wasn't apple and it would not fix the problem. So weird how they are the exact same thing but it won't work unless its actually apple.  Did apple install a chip in their USBs that makes it not work well if you use another brand?

---

I also had to use an Apple cord to get it to work

---

Yes, this worked for me too. Changed the cable and now my phone is restored. Thanks!

OMG, can't believe this worked. I have had problems with the last 2 updates and then again today. Tried changing the cable and it worked like a charm on my iPhone 6s+.
