9006 error while upgrading to iOS7 ... iOS upgrade failed ... service unavailable

This is nothing new. Every-time there is a new iOS update from Apple, this 9006 ghost flares up. Following are the quick reason and remedies as I gathered from different fora. I had to try them all before hitting success.

1. It might be the storage space to start with. 990 MB for the update to download and and another 1 GB for update to run. For the safer side set aside at least 3 GB.

2. Turn all the cloud backups off. It silently goes to iCloud, if your settings say so. Don't run upgrade and backup in one go. Do it one by one first backup. Then upgrade.

3. Try closing the iTunes. Getting and update and old windows gimmick the restart :). It has worked for some. Remember there is an iTunes upgrade also released today (18/09/13) for OSX 10.8.5

4. Try disabling any antivirus or third party security software or traffic monitors. We have seen similar problems during iOS5 upgrade too. Apple might be silently redirecting you to its additional service mirrors (I am not definite on that but I think so) that your monitoring software might not like.

5. Next thing is checking for default http(80) and https(443) ports on your router. The ports should be enabled and access should be allowed. (If you have never messed up with your router, probably you can skip this step)

6. Check for any firewall blockages on * (star).apple.(com) should be allowed.

7. Due to the peak load experienced by Apple (which might continue for another 12 hours) there are chances that your downloads are corrupt. So you might want to start all over again and delete any existing downloads (most probably they will be corrupt and the reason behind 9006 error).  Delete any unfinished downloads at following location
Mac OS X

Windows 7 

C:\Users\[username]\AppData\Roaming\Apple Computer\iTunes\

Windows XP
C:\Documents and Settings\[username]\Application Data\Apple Computer\iTunes\

 Look for your device updates in the folder and delete any unfinished or (finished) downloads.

NB: If trying over the air i.e directly from your iOS device also does not work and you see something like the second screenshot, it can generally be a network issue. You might be stuck up with a screen like this

This is 99% a network problem. Ensure that you perform step 7, go out for a lunch. Come back and try again.

Happy Upgrading
