Caution: Upgrading to iOS 8 GM

Foss · Sep 9, 2014

So I just downloaded the IPSW from the dev portal. Synced and backed up my iPhone 5S on the most recent beta build of IOS 8. Then the magic moment to manually upgrade caused iTunes 12 (latest on Yosemite) to crash. Now my phone is stuck in DFU mode, and iTunes will crash immediately if my phone is plugged in at all. So be warned. I'm switching to my mavericks partition to try to install off the latest iTunes there. Update to follow.

I just finished installing the GM on my 5s with no issues.

Yeah it is pretty common around here that iTunes 12 crashes when in recovery mode

I read if you use Xcode 6 with iTunes 12 it will work fine.

On Yosemite with iTunes 12?

Do not use iTunes 12 for anything related to restoring/upgrading phones. It is broken

I'm having the same issue. iTunes 12, Yosemite Dev Beta 7. iPhone 5S

This happened to me as well. Installing the latest version of Xcode fixes it. I reported a bug and Apple is aware of the problem. Hopefully fixed soon.

Thanks for the solution! I'm going to upgrade Xcode now. I should have upgraded my iPad Air before my iPhone. Lesson learned...

Considering Yosemite is not even released...probably not a good idea. If you are running Yosemite on your main/production Mac, shame on you.

Just download recboot to get the phone out of DFU. I had the same problem.

I'm not. I was just asking. I'll just boot into Mavericks.

Shame on you for jumping to conclusions.

How does Xcode fix it, iTunes will open normally after installing Xcode?

Thanks for the tip. Downloading Xcode 6 now.

It happens to us all. I can't take credit for the solution though! I found the answer here. There are actually 2 solutions in there but the Xcode route is probably the better solution. Perhaps the mods could merge the threads?

Is the DFU problem related to trying to restore a backup or if you do a clean install are you okay?

If you try to put the phone in DFU mode in iTunes 12 as it is, iTunes will crash.

Dan70 · Sep 9, 2014

Ah so don't put it in recovery mode, just update without, is that right?

I'm a bit lost sorry.

humar · Sep 9, 2014

I updated without DFU on beta 5 and my 4S was stuck in recovery mode... I don't know if this could happen with the GM.

Am3r1ca16 · Sep 9, 2014

tooshaggy · Sep 9, 2014

I am stuck in DFU.... my work computer has Yosemite, and my mavericks computer is with my wife.

How do I fix it in XCode?
