iTunes could not connect to iPhone - 0xE8000035

Hi,

I had this problem with my PC today also, iTunes was not able to connect to the iPhone. I thought it was the phone at first and I looked around online. What I did to get it working again was I completely unistalled iTunes, Quicktime and pretty much anything else that said Apple Inc. on my computer. Then I used a registry cleaner to get rid of any files that may have not been deleted in the uninstall process. I rebooted, reinstalled iTunes and it connected to the iPhone without any problem.

The issue seems to be an iTunes issue (at least for me), perhaps your laptop once had iTunes installed and is keeping some sort of residual files that may need to be removed. That is the only thing I can think of. I'm not a computer whiz, but this is what worked for me. Hope it helps 🙂

yeah i tried removing itunes, quicktime player and everything else that has to do with apple. but it didnt work. then i just thought i'd update to service pack 3 and it fixed whatever the problem was.

I have the same problem, and I am all Mac with no USB hub in the middle.

MacBookPro 2.5G, 4GRAM, OSX 10.5.4
iPhone 2nd Gen running 2.0

Won't sync at all.

You could call support? I am sure they are aware of these issues and want to resolve them, especially if the phone is new...That would suck. Call them...

All I did:
1. Charged my battery
2. Restarted the "Apple Mobile Device" service... You could also reboot 🙂
3. Replugged Iphone...
I chose not to restore. Iphone came back just fine... I did have the option to restore, but didn't see the need.

(I choose Microsft, but my wife has an IPhone 😉

I've been having this error for about three months. Along with the E8000035 error, I was getting many WPD-MTPClassDriver errors in the Event Viewer System Log. After viewing the previous notes in this thread, I looked at my USB setup.
I have six USB ports with only two "permanent" devices plugged in: a 4GB USB Key serving as a Ready-Boost cache, and my Epson RX620 printer/scanner/etc.

I turned off the RX620, and voila! The iPhone was able to stay connected and sync up.

While it sounds as if the RX620 was the culprit, the timing of the errors starting matches with when I installed a second hard drive in my computer. I'm wondering if that pulled down the power enough to affect the USB circuitry.

Hey nlkw!
Can you tell me which Service Pack 3, that you downloaded,
it is giving me 3 options: Service Pack 3.docx, Service Pack 3.pdf, and Service Pack 3.xps.

Thanks!

Suddenly had this problem on MacBookPro...
I disconnected ALL other USB devices e.g. mouse & keyboard, and could finally sync the iPhone.

i have downloaded SP3 But it still won't connect

Based on some of the answers here, and on my own experience, it would appear that 0xE8000035 can be related to USB (or probably more precisely IRQ) overload. My Win XP sp3 machine seems to get flakey with all Apple products if I have more than 8 or so USB devices connected. So one solution might be to disconnect some devices

I had this problem when i tried to update to 2.2 it appeared however the next day i tried day the error didnt appear. a week later when i tried to sync my iphone the error came up again.

I just ran into this problem. I "solved" it by switching off my laser printer. The iPhone was connecting directly to my iMac. I'd say this is a hardware problem with some Macs.

I have been struggling with this problem for a few weeks.

I have had my itouch for about a year and used it on my laptop that had XP. When I bought a new laptop (with vista) I started getting this error.

I finally had to hook the itouch up to my old laptop, restore the itouch and then plug it into my new laptop. It finally started working right. I couldn't manually restore the itouch using my new latop. It would go 80% of the way through the process and then give me an error.

The only thing I have a problem with now, is the fact that I can't plug the itouch into any computer running XP. I used to plug it in at work to charge it, but it won't even charge with XP.
