With the release of iOS 7 Beta 2 today, I felt like (finally) taking the leap and upgrading my iPhone to the latest version of iOS.
I downloaded the image and tried to restore (after taking a fresh encrypted backup) in iTunes 11.0.4, however I was presented with the following error message after the firmware was extracted:
I tried 3 times to restore my iPhone to iOS 7 in iTunes, before I gave up. Always the same error message. However, it turns out that opening the iOS 7 firmware ipsw file (iPhone5,2_7.0_11A4400f_Restore in my case) in Xcode did the job: after selecting my iPhone 5 in the “Organizer – Devices” application (which should have opened automatically when you opened the ipsw file using Xcode), I could pick iOS 7 from the iOS dropdown list and restore from there.
After installing iOS 7 on my device (took about 5 minutes), I needed to close and re-open iTunes 11 for it to recognize my phone again. After that, I was presented with a screen to restore from the backup I created earlier in iTunes. And behold, iOS 7 is installed! Or not … My phone rebooted approximately 10 times while restoring the backup, and each time when it arrived at a certain point (around “syncing application 10 of XY”) my phone rebooted again. It was somehow stuck in an endless reboot, even after canceling the restore in iTunes.
I restored the phone again to iOS 7 in Xcode, and by setting up the phone as a new phone in iTunes (instead of restoring from backup), everything runs fine now (albeit without restored backup so far). Manually restoring contacts and a few apps from within iTunes finished in a few minutes, after which I could start enjoying iOS 7 (at last!). A few impressions after the break:
