iTunes to iPhone "Unknown error 0xE800007F"

Me too - I have 5 IOS devices (2x iPhone 4, 1x iPhone 4s, 1 iPad 1 & 1 iPad2) trying to sync to my iTunes.

They all suffer from this issue.

No solution yet; knowing what doesn't work is the first step -

Platforms: iPhone 4s iOS 5.0.1 (jailbroken), mac OSX10.7.3, iTunes 10.6.

1. Forced uninstall of iTunes 10.6 (because Lion won't let it go)

2. Removed apple mobile device services (including theframeworks and .kext).

3. Reinstalled iTunes 10.6

Problem persists. When iPhone is plugged into computer, the following popup "The iPhone '<insert name>' could not be synced because the sync session could not be started." 0xE80007F pops up 2-3 times per week when phone is plugged in. Booted from a fresh Lion install on external drive, and itunes could recognize the iphone over cable connection.

The frameworks and .kext files have been re-installed with the new iTunes installation. These are the drivers for the UNIX platform OSX is built on. I thought this might enable the mac to 'see' my phone and start the sync session over a wired cable. Mad bummer.

iPhone is able to wirelessly sync (plugged in or not), so I'm not totally SOL like most in this thread seem to be (no sync at all). Could a few brave souls venture into terminal to try this on their respective systems? A solution looks to be unreachable from the apple folks. Their 'genius' in-store support could only come up a full Lion re-install. Maybe a developer or knowledgable CS folks could dig us out of this hole.

I have finally just given up on wireless syncing. Turned off the option, and the errors are gone. It was a cool feature, but not worth all of this hassle.

There,s a button beside the reply button for the 1st post, saying" I have this question too" only 50 ppl have the same question.

Anyway I'm using a netgear modem, ive seen problems in other posts using a linksys one as well, i think it's something to do with using a PC Windows OS, figures ~ unless someone else in this thread uses Mac?

Almost everyone here found that thread because we were searching the net for the error code we get in iTunes. It doesn't matter if that thread is created in the "itunes for mac" section, the error is the same.

Also, forget about the netgear/linksys possible issue, I am using an Apple Airport Extreme router and I get the trouble too.

Thank you for the hint about "I have this question too", I hope everyone here will go click that link if it can help resolve that issue.

Yes, we should all do this. The count is now 60. Can we make it 600?

Yes we can: As flareslayer says, go to the first post of this thread (click the "1" in the page navigation list on top or at the end of one of the thread pages) and klick "I have this question too" beside the "Reply" link.

See if it helps…

Adding my voice to alert Apple to this annoying problem everybody I know has with their IOS devices. Both Mac and Windows users are dealing with it. I gave up using the feature with my iPhone a long time ago. I was clicking OK to dismiss the error message 8 times a day. But I got an iPad and decided to give it a try. Yesterday, I dismissed the message 16 times. Somehow, activating sync over wi-fi with the iPad causes iTunes to look for my iPhone as well, even though I told it not to. Anyone else see this behavior?

Funny thing is, iTUnes does detect the iPad and it does synch if I charge the device. It’s like iTunes keeps trying to “ping” the device and trips up about 8 times a day.

Anyway, this feature is just as unusable with my new iPad and so far, everything about iCloud is a failure for me. I use Dropbox to fill that need (and Spotify for music) which means I don’t have to sync with iTunes. I suspect this is why the issue is not being addressed: Apple knows synching is less and less needed. But why is everything iCloud so terrible?

Installed IOS 5.1.1 hoping for fix to this bug. No errors in 90min since I updated.

Great news! Is this in iTunes 10.6 & Mac OSX 10.7? Some with jailbroken iPhones have held off on iOS 5.1, this might swing me to update.

Still a problem for me with 5.1.1 Had to close a dozen error messages this morning.

I've got the same problem and it seems to me that this is an iTunes and not an iOS issue.

not seems, it IS an iTunes issue

same here! (MBP late 2010, and iTunes 10.6.1, with iPod Touch 4g rinning iOS 5)

I have the same problem with iTunes 10.6 on Win 64 Pro with iPhones 3GS and iPad 3. It has been a problem ever since wifi sync was released (on my iphone and then on the iPad when I got it - both have the latest software as of 5/21/12.) I tried to fix it by removing iTunes, Bonjour, Apple Mobile Device Support, Apple Software Update and Apple Application Support. Rebooted. Reinstalled iTunes 10.6. Problem still remains.
