Update of iOS to 5.1.1 - Not as Smooth as Usual (Hurrah for Backups)

iOS Update


I first saw that there was an update to iOS from an online source, so connected the iPhone and checked. Indeed there was: version 5.1.1. I usually sync by iOS devices via wifi. I cancelled the download and backed up the iPhone as a first: highlight the device in the left column of iTunes, press the Option key and click on the mouse/trackpad. From the menu, select Backup.

Once that was done, I clicked on the download button (it now showed that there was one available) and a panel displayed the details:


iOS 5.1.1

This update contains improvements and bug fixes, including:

  • Improves reliability of using HDR option for photos taken using the Lock Screen shortcut
  • Addresses bugs that could prevent the new iPad from switching between 2G and 3G networks
  • Fixes bugs that affected AirPlay video playback in some circumstances
  • Improved reliability for syncing Safari bookmarks and Reading List
  • Fixes an issue where 'Unable to purchase' alert could be displayed after successful purchase

    I was then showed the Licence Agreement panel. The download began and began to install automatically. With my (allegedly 7Mbps) connection, the update took about 15 minutes. The update is verified with Apple and the process begins.


    But then I had a message to tell me that the iPhone could not be updated. The device was no longer shown in the side panel and on the iPhone was a "connect to iTunes" image. I pulled the cable, reset the phone and the same image appeared. This is the first update ever of an iOS device that has given me this sort of problem. This was a blow: I have things planned for today.

    When I reconnected, iTunes gave me one option: Restore. It was just as well I had done that backup this morning.

    It was restored to factory settings and restarted. "When the Set up your iPhone" panel appeared, I was given the option to set it up as a new phone or to use a backup. The button for this displayed the latest (7.22 am) backup which I used which also restored the phone name (from the vanilla, "iPhone"). When done (about 20 minutes) the iPhone restarts again. The progress bar on the screen went across fairly quickly while in iTunes I was told that the software was up to date: the phone then began to sync automatically. This took ages, but I do note that the reloading of apps seems to take place one screen at a time. I will check the settings later but an initial glance shows that all is well.


    In the meantime, I tried the iPad, but ignored the warning about connecting by cable (we live dangerously sometimes). The last backup, should I have needed it, was from the day before. The download was around a minute. It installed, restarted and is just fine. There may be a lesson here.


    As a note, from the looks of the online sources, this update was released at about 1am Thai time. A support page (link from AppleInsider) shows information about security changes with the update and some of the problems that have been addressed. At this time, I have seen no reports of others having problems.
