You don't need to reboot Windows.


Leave your iPhone connected to your PC then:


  1. Quit iTunes
  2. In task manager click "show processes from all users", sort by description and kill everything "Apple". Also kill the process with the image name AppleMobileDeviceHelper.exe
  3. Click Start > Run > in the Open text box copy & paste the following - with the quotes - "%ProgramFiles(x86)%\Common Files\Apple\Mobile Device Support\AppleMobileDeviceHelper.exe" and press OK.
  4. Open iTunes

What finally worked for me was logging on as administrator and uninstalling /reinstalling iTunes. Then I restarted and l logged in as normal. I then connected my phone to my computer and it worked. I don't remember the steps to log in as administrator-just google it. That's how I got instructions.


If you already have update 5 and can update wirelessly, I would try that. It wasn't an option for me because I hadn't updated before.


Good Luck!

applefan ...


1. Open My Computer

2. Click on System (C:) drive

3. Click on Program Files folder

4. Click on Common Files folder

5. Click on Apple folder

6. Click on Mobile Device Support folder

7. Now double click on the AppleMobileDeviceHelper.exe file


I am using Windows XP. If you are on another Windows platform, the location of the AppleMobileDeviceHelper.exe file might be in a slightly different location. If you can't find it, do a search on your PC.

Cyclist -


I suspected this was the problem, but I had already restarted and it hadn't helped. My next step was booting the process manually and you led me right to it. Thanks 🙂


For some reason running the path directly did not work, but I visited the folder you mentioned and ran the process manually (AppleMobileDeviceService.exe, followed by AppleMobileDeviceHelper.exe), and it worked. Thanks for speeding up my troubleshooting 🙂


Windows 7 Ultimate x64
iTunes 11

That didn't work for me and I've tried everything on every thread a few hours of tourture. I'm running Windows 7 64 Itunes 11.0.2.1 But you lead me to a new path which worked.


Close Itunes - Go to Task Manager - Services tab - select Apple Moble Device - click Services at the bottom - select Apple Mobile Device Manager - click stop on left side - wait a few seconds - click start - now open itunes - connect iphone and blam it recognized it!


Thanks for starting me down the path ReanimationXP!

I've had this exact issue since the very first day of using iTunes WIFI sync, it appears that Apple just don't care at all about the "it just works" mindset. These forums, and many others, are choked with this topic, only to have absolutley no fixes provided by Apple (I've contact support and also Genius bar without any success).


Apple, at least write software that provides some logging so we can figure something out for ourselves, or perhaps just write stable code that works.


Added to this is the commonly recognised iPhone5 WIFI throughput issues, also widely discussed & people are logging support cases/visiting genius bar......yet it's a continuing problem.


Starting to re-think iOS moving forward, whilst the walled garden is great when it works.......it soon becomes a prision when it doesn't.

I rec'd this error code when I connected my iphone 4 to iTunes with a non-Apple cord. (I was travelling and had left my charger, etc. at home, found an "Apple Style" charge cube/cable at a gas station, and bought it for a few dollars.) It charged the phone fine, but would not sync w/ iTunes.
When I got home and used the original cable that came with my phone, there was no problem.

Here's an improvement on ozsmacd's batch file that will fully cycle iTunes (even if it's running with devices connected), fix this issue, and tell you what it's doing in the process.


To use it, paste into notepad, pick File > Save As.
Change "save as type" to All Files, and then name the file "fixitunes.bat"


This will only work on a 64-bit version of Windows. Tested on Windows 7 x64 and iTunes 11.01.

Have found a permanent quick fix... I have had ths problem for months now, in the past i have tried uninstalling itunes on my computer and re-installing it but with no success. I tried this again at the weekend and itunes has been completely revamped and it worked straight away finding my ipod immediately and more to the point finds it everytime my ipod is connected and i go to itunes :-)

Try turning your phone off and then back on.


I had the same problem and tried going through the steps given by others for "AppleMobileDeviceHelper.exe", but this did not work for me.


I tried various things and finally called AppleCare. The first tech I spoke with had me uninstall iTunes and some other related things - mobile device support, update, Bonjour, etc. Then I downloaded iTunes again. I still had the same error code when I opened iTunes and connected my iPhone 5. I just kept getting the same error code (0xE80000084), again and again.


The technician transferred me to the next level of support (who was great, by the way) and he had me try a couple of things, and then asked if I had turned off my phone, which I had not.


I closed out iTunes, made sure the phone was not connected, and then turned off the phone. Believe it or not, turning off the phone, and then turning it back on, and then connecting the cable to the phone, seems to have solved the problem. The phone shows up now on the left side bar, the phone sync's and charges, and I have not had another error code, popping up.


So, hopefully this has solved my problem. If so, what a simple "hit yourself on the head, why did I not think to do this first", thing it is -- but so far, so good.

I have found that killing all instances of ATH.exe, and then disconnecting and reconnectring the iPhone works just fine when this happens. 12 seconds or so.... still... come on Apple... I shouldn't have to do this and clearly a lot of people have this problem.


I've heard that disabling wifi sync will help but I've not tested that additional step.

I am also receiving the same error message whilst trying to sort out my daughter's forgotten password on her iPod touch. I am not getting any of the dialogue boxes you are all mentioning when following the instructions. I have tried cyclists method but don't get the 'show processes from all users' when I open task manager. I am a complete technophobe but don't want to have to make an appt at the apple store.... PLEEEASE can anyone help?
