iTunes to iPhone "Unknown error 0xE800007F"

I have Wi-Fi Sync active and it works great unplugged from power -- but when I plug my phone into power and it starts syncing, iTunes says the following:


"iTunes could not connect to this iPhone because an unknown error occurred (0xE800007F)."


Searching gives me zilch. Anyone have an ideas? Everything is running the latest verison of iOS, etc., etc...

"As for Macs, (I don't know why anyone on a PC is posting in the mac forum anyway) make sure your wifi router is on the latest firmware and that your iPhone is connecting to wifi ok in general. That's what they told me."


Well, of course, a problem of this sort could only possibly be happening in PCs and never on a Mac. Oh no, maybe I'm wrong after all. Wouldn't it be slightly silly to have parallel but identical threads for PCs and for Macs?

You have to love Apple Fanboys. This is exactly the kind of people that do more harm than good. That comment was uncalled for and quite frankly offensive


For what I'm seeing, the issue is very similar on both OS, which indicates that it could be more an issue of iOS than iTunes itself, as it common to both. And the issue is still open on both forums so this suggested segregation by Windows and Macs is irrelevant

I found this thread searching for the error text -- not searching for "error on iTunes For Mac Only".

Since it's happening on both OSX and Windows does it really matter what thread we're posting in?


As for Windows users, someone in this thread said they talked to Apple who suggested they follow these instructiions http://support.apple.com/kb/HT1925?viewlocale=en_US to fix the problem. I tried it and it didn't fix anything.

add one more to the list. more reports hopefully more attention. this happens to me, I'll assume it has to do with wi-fi syncing, since it happens when my iPhone 4 is showing up in iTunes over wireless. I tend to leave iTunes open because of the automatic downloads, I never know when I'm gonna plug it in and stuff, or when I'll want to access my library through Home Sharing.


As such, this message pops up by all I can tell just at random times. It's VERY annoying though. I'll try and restore iTunes from minimized state and it's seemingly frozen, though I know by this point it's because that error message is showing as a modal dialog box and I have to hit OK.


I'm running iOS 5.0.1, but it also occurred in the initial release, 5.0. I have the latest version of iTunes (64-bit) 10.5.1.42. Just as I switched over to get that version, there it was, sitting for me. The iPhone still shows as connected fine, and is not trying to sync. Majority of the time it happens, it's not plugged in to a charger, it's just on my desk or something. It really shouldn't be a range or signal issue considering I'm sitting only feet from my router, and it's an N router. No other problems with it elsewhere. Running Windows 7 Ultimate 64-bit.


Would love to see this fixed, since if I leave it open, I can switch over to iTunes and there'll be 3, 4, 5 maybe instances of the error I have to click out of.


The only odd behavior I have found is that artwork or other metadata does not seem to sync over until I physically plug it into the USB port and do a manual sync. Same with deleting files... I'll delete files from the device or in iTunes (when it's wireless) and it won't remove them (or rather, it removes the entries only from the device the delete was done on, but I believe it only removes the pointer or entry to the file, and doesn't actually remove the file until a tethered sync. Adding files works, though. I can drag files onto the iPhone and they'll copy over fine... just removing or making changes to metadata seem to not work wirelessly.


That's about the best/most info I can give, as there's really no clear trigger that it happens, and I can always hit OK and access the iPhone's contents from the list with no problems at all. Maybe it has something to do with like... the wireless cutting off after so much time being locked? It seems I read somewhere that after it's locked the wireless will cut off after 10 minutes or so to preserve battery? (I could be wrong, it just seems familiar somehow). iTunes then thinks it has lost the iPhone out of range or something and throws up an error? Thing is though, at any time this happens, I'm not trying to sync, I'm not trying to access the phone... I just happen to have iTunes open and the phone around within range to be picked up. No clear definition to what that error code even means specifically but I'm sure the developers surely must know.

I called Apple last weekend. The guy I spoke with had not heard of the problem. I referred him to this post. He then stated that considering that Apple had sold 7 million new iphone 4S and there were only a handful of posts, the problem could not be related to IOS 5 or itunes. Tried to blame it on Microsoft Security Essentials (even though problem exists on both Apple and PCs). Totally lame. It was a waste of my time.


As a side note, in addition to the inconsistent wifi syncing problem, I've notice that when I have the wifi enable on my iphone 4 and am watching a video on itunes on my HD TV (which video is already downloaded on my PC), the video will get laggy three or four times during a 30 minute show. If I turn off the wifi on my iphone, I don't have the problem. Mentioned this to the guy also. Again, not an IOS 5 or itunes problem.


In June, Steve repeatly stated that "It just works." No it don't. Do something Apple.

This is bad, he's probably a typical Apple Fanboy who cant take any critism about Apple products. Anyway my friend has same problems but hasn't contributed to this or any other post on this forum.


Just to let you know I used to get this error on both my iPad 2 and iPhone 4. I stopped using wifi sync on my iPhone4 now I very rarely get this problem.

This is my chief compliant w/ Apple. As much as I like their products, they are incapable of acknowledging that there are ever any issues w/ their hardware or software. As much as everyone bags on Microsoft, at least you can goto their Knowledge Base on Technet and find a list of known issues, a workaround if there is one, etc. With Apple, you get utter silence or worse...they blame everyone else for their problems. 10 pages in a support thread of people w/ the exact same problem clearly speaks to an issue. Of the 7 million sold I bet a substantial percentage have no idea how to turn on wi-fi syncing.
