Error 17 could also crop up because of the outdated version of iTunes and too sensitive security software. If you have encountered this issue while upgrading your iOS device and are looking for quick ways to troubleshoot it, have a go at these viable solutions.
How to Fix iTunes Error 17
- Disconnect your iOS device from the computer → reboot your device → reconnect it to the computer and try to update again.
- If you have another available, try to use it to connect your device with the computer.
Check Your Network
Since we're talking about connectivity issues, most of the time the issue lies with iTunes trying to – unsuccessfully – connect and download the required IPSW file from Apple's server. This doesn't necessarily mean your network is down or buggy but checking it helps.
If you are on Wi-fi, make sure it's stable. If you can switch to LAN till iTunes downloads the file, do it for a stable network. But if you are sure your network is working just fine, jump to the next tip.
Temporarily Remove Your Security Software
If you have installed security software on your computer, test it to find if it's preventing iTunes from doing its usual task. It might be interfering with your computer's connection to iTunes.
Hence, try to temporarily remove your security software. Some security apps may not uninstall completely. Therefore, you will have to download and run a cleanup utility to remove it. If you need more help, contact your security software, provider.
Reset Hosts File
The Hosts file is basically used by the operating system to map hostnames to IP addresses. Try resetting it.
Reset the Hosts file on Windows
Step #1. First off, open Notepad.
Step #2. Now, you have to copy the following text. Then, paste it into the file.
# Copyright (c) 1993-2006 Microsoft Corp.
# This is a sample HOSTS file used by Microsoft TCP/IP for Windows.
# This file contains the mappings of IP addresses to host names. Each
# entry should be kept on an individual line. The IP address should
# be placed in the first column followed by the corresponding host name.
# The IP address and the host name should be separated by at least one
# Additionally, comments (such as these) may be inserted on individual
# lines or following the machine name denoted by a '#' symbol.
# For example:
# 220.127.116.11 rhino.acme.com # source server
# 18.104.22.168 x.acme.com # x client host
# localhost name resolution is handle within DNS itself.
# 127.0.0.1 localhost
# ::1 localhost
Step #3. On the File menu, you have to select Save as → type “hosts” in the File name box. Then, save the file to the desktop.
Step #4. Now, close Notepad and then open the folder
%WinDir%\System32\Drivers\Etc. To do so, just swipe in from the right edge of the screen and tap Search → enter run → click the Run icon.
Alternately, you can point to the top right corner of the screen → move the mouse pointer down and then select Search → type run → Run icon.
Step #5. Next up, you need to type
%WinDir%\System32\Drivers\Etc in the Open box → select OK.
Step #6. Now, choose the Hosts file, select Rename → rename the file as “Hosts.old”.
Step #7. Up next, you need to copy or move the Hosts file which you have just created in step 3 to the folder
%WinDir%\System32\Drivers\Etc . If asked to enter an administrator password, tap or click Continue.
Reset Hosts File on Your Mac
