An invalid response was received from the device?

If your phone is not jailbroken restore it using iTunes.

I'm facing the same issue and I just started using my iphone about 15 days ago and synced it twice so far but ever since i reinstalled windows and updated itunes, its giving the same error...

Explain why and how you reintalled Windows. Did you do a fresh install, or did you do an upgrade? What version are you using now, versus what you were using before? Did you install over an existing version, or uninstall and reinstall? Which iPhone are you using? What version of iTunes do you have?

It may just be your USB cord. Have you tried a different cord? This sounds hardware related and not software related. If you can't get it to work using a different cord, you may try taking to the Apple Store.

Also, you may even try re-installing iTunes. If you can, get a friend with an iPhone and see if your PC can detect their phone, that would help isolate it to being YOUR device.

Also, if you re-installed Windows recently you may check for OS updates. If it's Windows 8, you may try running iTunes in Compatibility mode for Windows 7, or run as administrator.

Thank God its working now! As for the answer to your question, read the first para, for attempted solutions, read second one, for the one that worked, read the third one. I'm using an Iphone 4 Factory Unlocked with IOS 6.1.3 (no system change) and iTunes 11.0.4.4 (after the upgrade).

My laptop had a virus because I didnt have any antivirus installed since I thought windows 8's built in Windows Defender was an antivirus (and well enough at that, but I was mistaken). After installing Kaspersky internet security and scanning my laptop, I removed the virus but still reinstalled windows and removed all my content from the laptop (the docs that mattered) and formatted it. After reinstallation, I reinstalled all the softwares and iTunes, which then asked me for an upgrade and I upgraded to vesion 11.0.4.4 and when I got done with everything and plugged in my phone and it didnt read my phone and gave the error I mentioned before.

I Synced my phone when I had the previous version of iTunes (before the Sep 10 IOS 7 and IPhone 5S / 5C Launch), but the newer version wasnt working. I read here about reinstalling iTunes, the apple mobile support driver and QuickTime (which I did twice), about rebooting my system before using it (which I did), about pausing my internet security/antivirus for a while (which I did againnnn!!!), but to no avail, I even went so far as to erase everything on my phone, and still no luck, and I even went and checked for the apple mobile support driver and iphone drivers in my recognized devices when the phone was plugged in and removed the driver and plugged in my phone again for the software to reinstall but no luck...

Then I uninstalled my internet security (antivirus), uninstalled iTunes, reinstalled it (the latest version all along), and then plugged in my phone (without changing any setting or erasing the network settings) and thank God it started working again... But I was ticked at having to download and reinstall my apps on iTunes and my cell again... ... ... anyway, do tell me it works, i mean, unistalling your internet security, iTunes and then reinstalling them and plugging it in! 🙂 good luck!

I did try the chord, but that wasnt the fault, but it started working after I did the steps mentioned above, and it worked about 15 minutes or so after I wrote that, though I was considering what you're saying now, thanks, I'll keep that in mind if any of my friends have an issue like that 🙂

Just as another side note, Kaspersky is one of the worse anti-virus softwares to work with iTunes and other Apple software and devices. If you were to search this forum, you would find numerous issues with it, and it does make it very difficult when it comes to updating iOS. You will usually have to disable it to accomplish the task. There are settings in Kaspersky that allow for ignoring iTunes and other Apple software but it doesn't always work. Keep this in mind when it comes time to update iOS on the phone. Glad everything else is working now.

thanks, will keep that in mind, as for the problem, did you look at your iTunes wifi sync option? i guess changing the name of the system also has issues in cases of reinstallation, and if not, try using iexplorer to get your data out or upload it on iCloud and then reboot your phone, or go to the apple store just to get that outta the way first

Maybe you misunderstood. I do not have any issues with my setup. Everything is working just fine. I was trying to provide you with information on how to get yours working again. Have a nice day.

I got it, i was just saying if theres an issue with your setup, you could try that

OK, I had same error (no code) that said my iPhone could not connect to iTunes, no response from device, etc. I was able to get around it last night.🙂

Background is that I had not sync'd my phone to my Dell Windows 7 laptop since early December. I had also done iOS upgrade, and am current rev (7.0.6)

Also my iTunes at rev 11.1.5.5

First thing I tried was rolling back my iTunes version to when I knew it worked, no help

The shut down my anti virus, no help.

Went to control panel\system\device manager and tried to re-install iPhone driver. It said the driver was current, and took no action (I think this is related).

This is where I regret being hasty. I used task manager to shut down iTunesHelper.exe, and AppleMobileDeviceHelper.exe*32.

After closing these two, I restarted iTunes and reconnected my iPhone, and it worked. One thing interesting I noticed. After using task manager toshut down the 2 running Apple related executables, when I plugged my phone back in, it reinstalled the iPhone driver. This leads me to belive that my driver was corrupted, but the running programs didn't recognize the need to reinstall the driver because it was looking for a rev, not a corruption.. Next time, I would shut the exe's down one at a time and re-open iTunes, reconnect phone after each to see what happens.

I know this may not be the end all, be all, but maybe it will give you somewhere to start. If it happens to mine again, I'll redo thisone step at a time and repost.

Thanks Chris, All of a sudden I was receiving the same error in addition to the iPhone asking me each time I connected it to the computer to trust it.

"3. Try a different USB 30-pin dock-connector cable."

The above suggestion is what worked. 🙂

I just disabled Kaspersky and reconnected phone , it worked fine with itunes, I believe the latest version of kaspersky has lot of issues with recognising certificates which causes this problem & an indication would be the notification from kaspersky when one connects iphone via cord to PC

I have the exact same problem and I'm trying to connect to a macbook. I've never had a problem syncing my music when I used windows, so yeah it very well could be a computer problem. I've done everything listed on this forum and unfortunately I've had to come to the conclusion that apple products really are **** because nothing worked. My theory is that since itunes is OWNED by apple, they have the authority to deny you access to music that wasn't purchased from them. I'm betting that's why this specific issue happens ESPECIALLY when using an apple computer. I think the best way to solve your problem is to get a windows computer and sync your iphone to that.

My anger derives from nearly all my music being deleted after trying to connect my phone to this computer. Now my macbook won't even recognize my iphone when I connect it AND I have no music AND I can't ever add more music.

Thanks a lot apple,

I am on Vista and after the latest 12.3 update to the iTunes software, iTunes no longer recognizes my iPod... with iTunes saying the iPod gives an "invalid response". I tried completely uninstalling Kaspersky and then uninstalling and re-installing iTunes but still get the "invalid response" message.

The only way I could get it working again is to do a system restore to back-out the iTunes update to the older release and then it sees my iPod again.

Is this just Apple's way of forcing me to buy a new iPod?
