Installing IOS 5.1.1 on my iPhone failed and now is not recognized by PC or itunes. All troubleshooting has failed. HELP!!!

Installing IOS 5.1.1 on my iphone failed and now the phone will not show up on itunes and is not recognized by my PC. I tried all troubleshooting Apple says to do minus uninstalling itunes. My wifes iphone still works fine with the same cable and itunes on my PC. ----- Help!

Hello. I was like this yesterday after upgrading 5.1.1. The proccess failed and the iphone only showed the USB cable with the iTunes logo.
What I did was connect the iphone to my wife's PC, and there, with a clean itunes installation, install a clean 5.1.1. Then, went back to my iMac and connect it again, and now it works.
But now, with my iphone working as new, it still cannot be showed up in itunes. I am still working on it.
Good luck!

This should solve the problem
Settings > General > Reset > Reset All Settings
It will not erase any of your personal data, just reset the settings.
Hope this helps.

I installed iOS 5.0.1 on my Iphone 3GS. I never can not write in my calendar. Anyone else having this problem after their upgrade?

I was going to suggest - Settings>General>Reset>Reset all settings, but if you are restoring to factory settings, that should restore the settings back to factory defaults. But if you are restoring from a backup, after restoring to factory settings, try resetting all of the settings and see if that fixes it.
It might be something in your backup.

Why? What happens when you try? iOS 8 requires an iPhone 4S or later.

Hi there,
I've just installed ios 7.0.6 on my iphone 4 and now lost voice on outgoing and incoming calls.It rings on incoming and I'm told rings on the recipient's 'phone, but then no vocal communication...its just dead. My simm is ok, i've checked it, I've done a full clean and restore of the 'phone. Still no calls.
I've not caused any physical or water damage to the 'phone. I would welcome any help/suggestions to get my calls back asap.
Please help.

Have you tried restarting or resetting your iPhone?
Restart: Press On/Off button until the Slide to Power Off slider appears, select Slide to Power Off and, after It shuts down, press the On/Off button until the Apple logo appears.
Reset: Press the Home and On/Off buttons at the same time and hold them until the Apple logo appears (about 10 seconds).
Also consider deleting and reinstalling the Mail Account in question.

How do I install ios 5.1.1 to my iPhone 4 (running on ios 5.0.1) if ios 6 is out?

I am currently trying to install ios 5.1.1 on my iPhone 4 (who is running on ios 5.0.1) but iTunes says "the device is not eliglble for the build". I have been trying to install it from a chosen ipsw as I don't want ios 6 to get into my iPhone.
Does anyone know how to install an ios that is not the latest version?

You can't because Apple have stopped signing 5.1.1 so if you want to upgrade then you'll have to upgrade to ios 6 which is the latest or not at all. You won't be able to upgrade to 5.1.1 now that 6 is out.

Can't install iOS 6.1.2 on my iphone 4s

I'm trying to install iOS 6.1.2 on my iphone 4s (currently 5.1.1) running OSX 10.7.5 and iTunes 10.7. I get a message " the iPhone could not be updated. This device isn't eligible for the requested build" Is it my system or iTunes that's stopping me?

This occurs when iTunes is unable to communicate with the update-and-restore server (gs.apple.com). This is most likely because it is being blocked, redirected, or interrupted by security software, hosts-file entries, or other third-party software.
Resolution
Perform the following steps to resolve this issue:
Install the latest version of iTunes.
Certain software applications can modify your hosts file, which can prevent your computer from accessing the update server. Follow the steps below to verify that your computer is correctly configured to contact the Apple update server.
Note: If an application has modified your hosts file, you may need to uninstall that application before editing or recreating your hosts file.
MacWindows
If the issue persists and you have TCP/IP filtering, firewall, or security software installed on your computer, follow the steps in this security-software troubleshooting article to correctly configure or temporarily uninstall your software. If you uninstalled software to resolve the issue, contact the manufacturer of that software for assistance with installation and configuration.
Some third-party routers may have default security or network settings that block access to the update server. If you are using a third-party router, disconnect power to the router and connect directly to the ISP source. You may have to restart your computer and ISP modem to establish an Internet connection before attempting to restore.
If the above steps did not resolve the issue, try restoring on another computer with a known-good Internet connection.

Well, no you can't because you can only update to the most recent software and that is iOS 7.
Also, do not duplicate your posts - there is no need.

HT201442 Error in installing iOS 7.1.1 on my iPhone 4

I was installing iOS 7.1.1 on my iPhone 4 and it had already downloaded but when I clicked install now, there was an error message that said, " there was an error in installing the software update on your device." How do I fix that problem?

It depends on how much you want the new apps. iOS 7 did slow down the iPhone 4 a little bit. Not a lot, but you will notice a bit of lag for awhile. You should get used to it and you will then be able to download the newer apps you are interested in.
iOS 7 does look very different from iOS 6. They did away with all the faux leather, stitching, glossy reflections and other skeuomorphic touches that had been the iPhones trademark look since the beginning. Google iOS 7 images and you will see what I mean. I personally like the "flat" look that they went with in 7 and the other features that come with it make up for it.
Some people do have a problem with battery life on their phones, but I think a lot of that comes from using the phone a lot in the beginning to see all the new stuff. But if you set it up the way you like and turn off the real battery drainers like push email and the screen animations (I got tired of those really fast anyway, I just want an app to open, I don't need to see it spring out of the icon) and your battery life should not be worse than what you are used to.
You will see a huge jump in performance between an iPhone 4 and a 5S.

Can I de-install ios 8.0.2 from my iphone 5s

can I un-install ios 8.0.2 from my iphone 5s

I'm sorry, but Apple does not provide a downgrade path for iOS. Because downgrading is unsupported by Apple we cannot discuss it on these forums.
