IPhone 3G - Unable to update to iOS 4.2.1

Using PC Win 7. Connect 3G iPhone via USB, shows its backing up, will never complete backup. If left alone iTunes will eventually lock up, and stops responding. I have 3GS, and an iPhone 4, both updated fine using the same PC, this problem only has occured with my iPhone 3G. The same problem happend on a diffrent PC, using Win 7, on 3G iPhone (different family member). Would really like some fresh ideas, because I'm at my wits end. Thank you in advance!!

If it is a 3G it cannot be updated beyond iOS 4.2.1. If it is a 3GS it can be updated to the current version (5.1.1). If you're not sure which model you have, check this article: http://support.apple.com/kb/HT3939.

Unable to update my iOS on my iPad and iPhone.

I am unable to update my iOS on my iPad and iPhone. Though I have had these devices and have been updating for over a year, the issue just started with this new release (iOS 5.1).
When I connect my Pad and Phone to iTunes (Windows PC with Vista), I am told that an update is available. When I update, iTunes tries to connect to a server. Then I receive the message, "There was a problem downloading the software for the iPad. The network connection could nopt be established."
When I try to update the devices iOS using WiFi directly (not connected to iTunes). The devices say, "Checking for Update..." and does not connect. It says, "Unable to check for update...An error occurred while checking for a software update...Cancel or Try Again"

I solved this by downlading the iOS update via wi-fi at another location other than my home. I would still like to know why this download did not work at my home as it has for over a year. I have made no changes in my firewall or security settings.

my iphone 6 plus after updating to IOS 8.2 seems to have a problem with the touch id witch doesn't work neither in home unlock nor in app store and when i'm trying to add a new fingerprint it says ''failed unable to complete touch id setup.Please go back and try again'' .

Hi Giannis,
If you are having an issue with Touch ID not functioning as expected, I would suggest that you troubleshoot using the steps in this article -
Use Touch ID on iPhone and iPad - Apple Support
Start with the section titled Clean the Touch ID sensor and then Get help with Touch ID.
Thanks for using Apple Support Communities.
Sincerely,

HT1222 My iPhone is unable to update its software to iOS 5.1.1. Any solutions?

I got an error message saying that my iPhone is unable to update its software. The error message gives me the option to close the message or go to settings, so I click settings but it just goes back to the software update page. Any solutions?

"Unable to Install Update - An error occurred installing iOS 5.1.1." There, is that enough to get an intelligent response?

What happens when you connect to computer and update via iTunes?
The Settings>General>Software Update comes with iOS 5 and later.
Connect the iPod to your computer and update via iTunes as far as your iPod model allows
iOS: How to update your iPhone, iPad, or iPod touch
You need itunes 10 or later and that requires OSX 10.5.8 or later
You have a 2G (vi the SN yo provided) and that can go as high as 4.2.1

Unable to update to ios 5.1 on windows

unable to update to ios 5.1 on windows on iPhone 4

My error message says "Unable to Install Update" 2nd line "An error occured installing iOS 5.1."
no specific error number/message.
With a generic one like that, it might be best to try working through the following document:

The typical cause is that the device has been hacked or jailbroken.

IPhone 5s won't update to iOS 8.0.2

My iPhone 5s won't update to iOS 8.0.2. I had been using beta versions of iOS 8 but even though there is a '1' in the Software Update box, it tells me my software is up to date (iOS 8).
However, I also get messages telling me my current iOS will expire in x days. I now have dozens of apps waiting to update, telling me I have to upgrade to iOS 8.0.1 or later.
I've tried to manually install iOS 8.0.2 but I get a message saying the firmware isn't compatible.
Any ideas?

Ask in the developer forum; someone there should be able to help you.

I have a MacBook 5,1 (13.3" aluminum from 2007 or 2008). Automatic updates will only let me get to OSX 10.5.8. Can I upgrade to Snow Leopard, Lion 10.6 or even 10.6.8? Also, will I have any issues with my iPhone if it's updated to iOS 7.1?

The 10.6 Snow Leopard DVD is in the Apple online store. You can get it for $19.99. You will need to be running 10.6.8 to access the App Store to order Lion or Mountain Lion. http://store.apple.com/us/product/MC573/mac-os-x-106-snow-leopard
System Requirements for 10.6:
Mac computer with an Intel processor
1GB of memory
5GB of available disk space
DVD drive for installation
Some features require a compatible internet service provider: fees may apply.
You can upgrade direct from 10.6.8 to 10.8 Mountain Lion without going through 10.7 Lion with the Late 2008 model 5,1 Aluminum Unibody. The Model 5,1 will probably run 10.9 Mavricks when it comes out.
10.8 Mountain Lion is a download from the App Store, the price is $19.99.
Mountain Lion will require at least 2gb of RAM but really needs 4gb to run smoothly.
As for third party programs see this list for compatibility with 10.8 http://roaringapps.com/apps:table
Also Mountain Lion doesn't run any Power PC programs. To see if you have any Power PC programs go to the Apple in the upper left corner and select About This Mac, then click on More Info. When System Profiler comes up select Applications under Software. Then look under Kind to see if any of your applications are listed as Power PC. Universal and Intel will run under Mountain Lion.
Before Mac switched to Intel processors in 2006 they used Power PC processors from 1994 to 2005. Power PC 601 through 604, G3, G4 and G5. Applications written for the Power PC processors need the application called Rosetta to run on Intel processors. This was part of the Operating System in 10.4 and 10.5 but was an optional install in 10.6. With 10.7 Lion Apple dropped all support for Power PC applications.
