Unknown error 0xE8003FFE in iTunes sync (Xcode 4.2, iOS SDK 5.0, iPod 2nd gen iOS 4.2.1)

Question

Probably I missed something, but I can't sync any apps. What I did:

• installed latest xcode+iPhone sdk 4.2
• installed latest iTunes for Windows (10.5.1.4)
• set up deploy target to 3.0 and current SDK to iOS SDK 5.0
• armv7 as base architecture, armv6, armv7 as available
• "build architecture only" unchecked

When I'm syncing with iTunes iPod 2nd gen with iOS 4.2.1 I have unknown error 0xE8003FFE. I tried with and without entitlements enabled. Everything works ok on iPhone 4 with iOS 5.0

Have I missed something with iCloud or some xcode settings?

Answer 1

Have you already tried resetting your iPod? If it doesn't work, try restoring from backup. But before you do I recommend that you backup your iPod.

I have just had the same issue (same error with armv7, on older devices only). Adding armv6 finally did do the trick. Follow the link to detailed instructions.
