Using iTunes to upgrade the OS on a 4th generation iPod Touch, the update downloads but when it attempts to install it the process fails with the following message:

The iPod "iPod Touch (4G)" could not be restored. An internal error occurred.

Any ideas what might cause this and how to avoid it?

Same thing here on my iPhone. I'm trying with another Mac right now. –  Gio Oct 12 '11 at 20:09

I've had the same thing on my iPhone 4 (never jailbroken or anything). I read somewhere that the Mac should be running the latest OS update first, so I'm going to try updating to 10.7.2. –  Magnakai Oct 12 '11 at 20:16
    
No luck with 10.7.2 with my 3GS. I don't now what's going on. –  Gio Oct 12 '11 at 20:50
    
@Magnakai I'm on Snow Leopard (10.6.8), not Lion, but I did install the latest updates before trying to update the iPod. –  Dan Dyer Oct 12 '11 at 20:50

I got it after several attempts. (iPhone 4, 10.7.2) –  Patrick McElhaney Oct 12 '11 at 21:17

It is server overload. Either keep trying or wait till the traffic dies down a little.

iTunes always logs an error when this fails - which error did you get?

Generic steps are worth checking if you haven't recently updated iTunes or the device.

A possible reason is bad memory in the device. Newer versions of iOS tend to have a progressively larger memory footprint; if the larger size crosses a boundary in to the bad RAM area, the device will no longer boot up. I know of at least one iPhone owner with this unhappy result.

@cksum, is a hardware problem the more complex or less complex explanation here? –  Daniel Lawson Nov 9 '11 at 4:47
    
@Daniel I'd say having a known server error on the day(s) a brand new iOS is loosed to the public (and the internet abuzz with similar occurrences) points more towards a "glitch in the Matrix" as opposed to some obscure issue with the devices memory. If my PC dies, I'm more inclined to see if the power cable came loose or that power is still being supplied before ripping it apart, testing the components. Any skilled technician always diagnoses a problem through a series of steps, incrementally working towards the more complex and rarer scenarios. –  cksum Nov 9 '11 at 5:52
