Problems updating iPhone 4s to iOS 9
Earlier, this morning (Swiss time), I updated my iPad 3 to iOS 9 via iTunes (latest version, OS X 10.10.5) with no problems. Now I am having one helluva time doing the same thing the same way for my iPhone 4s. When I connect it to iTunes, I am informed of the new update. I select to download but not install. After some time, this message appears:
"There was a problem downloading the software for the iPhone '...'. <reason>"
The reason given was first, "The network connection timed out," on subsequent tries, "An unknown error occurred (9006)." My antivirus program was not running, and neither was Little Snitch (prevents programs from "phoning home"). Finally, I decided to attempting the update over WLAN, and disconnected the iPhone and quit iTunes. On the iPhone I was surprised to find not the Check for Updates button but a screen informing me that the update was being downloaded. After some time, the screen changed to one informing me that the update had been downloaded, but doesn't tell me how to subsequently install it.
Any suggestions? I really hadn't expect so much frustration.
I am in the process of restoring from a backup, which I made just before attempting to update the first time. When the iPhone reboots i am greeted by a welcome screen and a slide labeled "> get update" or words to that effect. Not sliding it presumably would not have got me past that screen. I am not sure how far I will get, but I am expecting a bricked iPhone. Will update this when something happens. In the meantime I would like to know whether anybody else has experienced this problem.
