Try to backup and restore, as described here in the link below. If necessary force the iPhone in Recovery mode:

IOS 5.0.1 upgrade on iPhone 3GS,

Prior to iOS 5.0.1 upgrade on iPhone 3GS, I could readily connect to and use a variety of wireless networks at home, work, and on road.
Since installing the upgrade as prompted on device, I find WiFi is unstable to unusable.
Unless the device is sitting practically on top of a router, I cannot maintain connections.
If I am more than 2 ft out of direct line of sught of router, I lose my connection.
I have to date read and completed the following online suggestions with no success:
1-Restarted router - NO CHANGE
2-Reset Network Settings on device - NO CHANGE
3-Toggled in and out of Airplane mode - NO CHANGE
4-Completed various options for start/restart of device - NO CHANGE
5-Disabled all other services using battery at same time (Bluetooth/Location Services, Mail, Reduced Backlight even) - NO CHANGE
6-Forgotten prior networks - NO CHANGE
7-Attempted to assign Static IP to device on router side - NO CHANGE
8-Restored from backup - NO CHANGE
8a-Repeat 1-6 again - NO CHANGE
9-Restored to Factory state - NO CHANGE
9a-Repeat 1-6 again - NO CHANGE
10-Changed Router security from OPEN to most SECURE - NO CHANGE
10a-Repeat 1-6 again - NO CHANGE
11-Setup new router - NO CHANGE
11a-Repeat 1-6 and 10 again - NO CHANGE
During all of this multiple iOS 4.x devices and iOS 5.0 devices have been on the routers connecting as always.
The device in question functioned perfectly up to the point of iOS 5.0.1 so I know this is not a iPHONE hardware issue nor is it a ROUTER hardware issue.
I have seen this posted frequently and do not believe this to be an isolated state I am in.
Any thoughts and suggestions before moving to another manufacturer all together and get out of this Apple mindset.

Nothing personal (or maybe just a little personal), but simply copying my post from a day earlier as your own is not helpful to the Apple communities or people that coming here looking for support.
It does nothing more than add a duplicate post and decrease the chances that someone might actually include a reference to my original post, which came from MY OWN HARD WORK in troubleshooting my issues.
If you are having a similar issue, post the issue after doing your own leg work and describe in your own words. Don't simple steal someone else's hard work to troubleshoot the problem as your own effort.

IOS 7.0.1 upgrade on Iphone 5 failed, now stuck!

Hi,
Whilst upgrading my wifes phone it failed with "unknown error" now it's stuck showing the itunes - USB connection picture no matter what I do, have pressed power and home buttons to reboot with no effect - also now not recognised by iTunes or computor (Windows 7) when plugged in - help!?
Thanks
Sydney

Hi Sydneydog,
Welcome to the Support Communities! The articles below will help you troubleshoot the issue you are having with upgrading your iPhone. The first step would be to upgrade your iTunes software to the latest version on your PC. Then try connecting your iPhone again to see if it is recognized. Placing your iPhone in Recovery mode should get you to the point of restoring your phone. Data will be deleted, so a backup of your iPhone will be needed at this point.

Download iOS 8 once and upgrade all iPhones at home, how?

Is it possible to download iOS8 only once and use it to upgrade all iPhones at home?
I tried the following methods and they are just not working:
1. Connect an iPhone to the iTunes on Mac. I chose Download Only. Once downloaded the iPhone Software Upgrade, I upgraded the connected iPhone to iOS8. Then I connect another iPhone (used to be on another Mac) to the same iTunes. I had to download iOS 8 again. It's not using the same downloaded iOS 8 file.
2. I turned on the Caching Service (not Software Upgrade Service, i.e. for Mac Software) on the Mac Mini Server from the Server app. I then repeat step 1 above and got the same result. It seems that the Caching Service does not cache the iOS 8 Software Upgrade like what it does for other apps. (I think I may need to use some Apple Scripts but I have no such experience.)

It's for the family. Every member has 2-3 iOS devices to upgrade.
I agree with Csound on that, a family, even with a lot of devices will have to individually update. There are enough nuances in the iOS for different devices that you need to download for each. If you had 200 iPad 2's then there might be an enterprise way...but not a family with a mix of devices.

Major echo after iOS 7.0.2 upgrade on iPhone 5

After upgrading iPhone 5 to iOS 7.0.2 I get a major echo on calls that I did not get with iOS 7.0. How do I get rid of this echo? Verizon is my carrier.

No. The problem with the sound on mine is with the sound effects, such as the closing noise, shutter noise, alerts etc. It has a weird reverb effect. A hollow echo.
When I get on a call and put the phone to my ear I can't hear what the person is saying, like its coming out really quite but like it's coming from the speaker very quiet instead of out of the earpiece. If I put it on speaker though it sounds fine.
A friend suggested I put it in hearing aid mode which seems to have helped but still doesn't sound very good.
This didn't start until I upgraded to 7.0.2 from the 7.0 beta 6.

After ios 7.1.2 upgrade on iPhone 4S, my MacBook Pro does not recognize any photos to upload

My computer recognizes my phone, yet continues to state that there are no photos!

Try lauch iTunes.
Then connect the Phone/iPad
When it asks you to trust it, say yes.
Then try import.

If this doesn't resolve it you most likely have a hardware failure. Fortunately, your phone is in warranty, so if you take it to an Apple store they will replace it.

Upgraded my iPhone 5 from iOS 6 to 6.1. Lost all of my 250 contacts. The support person I spoke to gave me instructions that caused my backup (on my computer through iTunes) to be overwritten. Any suggestions?

A couple of nights ago I upgraded my iPhone 5 from iOS 6 to 6.1. All of my 250+ contacts were gone. I spoke to an Apple support person. The instructions she gave me, which I followed while she was on the land line with me, caused the backup file to be overwritten with the file that had 0 contacts. Does anyone have any suggestions? Has anyone had a problem with lost contacts when upgrading to iOS 6.1?

Thank you. I ended up performing the Restore after I did an Update, and performing the restore solved the problem----I now have a functioning iPhone with all of my data, pics, and apps on it. Fortunately I made sure that I backed up my iPhone before I tried to update to iOS6. Man, what a headache though, and it sounds like I had it easy compared to some other horror stories I've read. I won't update my iOS on my iPhone again; i've learned my lesson. It remains to be seen whether iOS6 will be worth it :-)

Is it possible to recover my data from iCloud backup without working wifi? I have as many other upgraded my iPhone 4S to iOS 7.0.2 with the result that the Wi-Fi or Bluetooth no longer works. However, i can connect to iTunes via cable but there is wrong version of backup.

Answer is no.
If you want the iCloud backup you have to have n internet connection, thus WiFi.
The not working WiFi has happened with quite a number of users.
It is not exactly clear what is the cause but there are suggestions to clear it up:
Some people have had success by removing an apostrophe from the iPhone name. If your iPhone is called something like “John’s iPhone” then this might work. Go to Settings > General > About > Name and change it to something with no apostrophe.
Some people have reported success by putting the iPhone into Airplane mode and then going to Settings > General > Reset > Reset Network Settings, but the problem may return.
You could also try going to Settings > Control Center and disable Access on Lock Screen then turn your iPhone off and on again.
Make sure that your router firmware is up to date.
Try backing up your iPhone and then restoring it. Check how to factory reset an iPhone for details.
If nothing is working for you, try contacting Apple or take your iPhone into an Apple Store.
Succes, Lex

Why is os 6 upgrade causing my iphone battery to drain?

Why has the os 6 upgrade caused my iphone 4 battery to drain unusually fast?

when I use the computer usb port to charge the battery, I found something strange:
battery indicator is showing 100% from my iphone within a hour
battery indicator is still showing "charging" from iTunes after two hours.
After two and half hours, the battery indicator is showing "charged" from the itunes.
The battery indicator might make you think your iphone's battery is fully charged from the iphone but it doesn't.
I had same problem from my 4s after upgarded to iOS 6 but Charged the battery overnight or more than two or three hours and it works fine now.

HT4623 upgraded my iphone 3GS to higher iOS but unfortunately my phone has reset factory setting and now i can't use it anymore... tried to connect to iTunes but it would only say: WE ARE SORRY, WE ARE NOT ABLE TO CONTINUE YOUR ACTIVATION THIS TIME...

tried to upgrade my iPhone 3GS to a higher iOS but unfortunately it had reset factory setting... now i can't use my phone anymore... tried also to connect to iTunes as instructed but only appears: WE ARE SORRY, WE CANNOT CONTINUE YOUR ACTIVATION AT THIS TIME... WHAT SHOULD I DO? THANK YOU...

No, you do not need to nor should you jailbreak your iPhone.
If you jailbreak your iPhone, you void any remaining warranty and lose
all support from Apple including this forum.
4 possible causes to activation server unavailable message:
1] activation server is actually unavailable. Happens very rarely and
does not last long on those rare occasions. Solution is to try again.
2] your firewall/internet security software/antivirus are preventing connection
to the activation server. Solution is to temporarily turn off your firewall/internet
security software/antivirun until you have activated your iPhone.
3] your iPhone has been jailbroken or otherwise hacked/modified.
4] the computer you are using to activate the iPhone has been used to
jailbreak an iOS device.
For causes 3] & 4] you are on your own as Terms of Use for this forum prohibit
discussion of jailbroken/modified iOS devices. Google may provide some direction.
Be advised that jailbreaking/hacking your iPhone may prevent the iPhone from
being able to be activated.

No WIFI after iOS 7 upgrade on iPhone 4s!

Dear Apple et al,
Like scores of other Apple customers, since upgrading from iOS 6 to 7 on my iPhone 4s, I have completely lost WIFI capability and experienced slower GUI performance in general. I have explored all other options including consulting Apple's Genius Bar to no avail. I have tried to downgrade the iOS back to version 6 but Apple has made this impossible. This problem has forced me to rely soley on costly 3G for internet access. Please help!
Sincerely,
Jacob

I have since reset the firmware on my existing router after reading that there may be compatibility issues with newer iPhones/OSs and older routers .. I also checked router wireless and network settings against Apple recommended settings on http://support.apple.com/kb/HT4199?viewlocale=en_US .. So far, situation appears improved. Let's see if that persists.

Re: Downgrading Oct 16, 2012 2:57 PM (in response to nbabbit2013)
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, but you can use Google to find information on how to install an older version of iOS on any iDevice.

After upgrading to iOS 5.0.1 in my iPhone 4 the battery lasts less by a 30%, it´s only me?

After upgrading my iPhone 4 to iOS 5.0.1 the load of the battery lasts less by 30% with the same use it had before. So far I read the upgrade was to correct the battery duration flaw. So ¿What happened?

You only get one download of movies.
