Here is the general solution to update problems: http://support.apple.com/kb/TS1275
Your specific error is:
Error 3000-3999: (3002, 3004, 3013, 3014, 3164, 3194, and so on) Error codes in the 3000 range generally mean that iTunes cannot contact the gs.apple.com server on ports 80 or 443. This may be because out-of-date or incorrectly configured security or firewall software is interfering, an entry in your hosts file redirecting requests to gs.apple.com, or due to your Internet proxy settings. If you are using a proxy, try without using one or with a known-good network. If that does not resolve the issue, follow iTunes for Windows: Troubleshooting security software issues. Error 3014 may indicate that you need to free up more disk space on the computer before trying to restore again.
If you changed the Hosts file this is most likely the cause. Edit the hosts file and delete all lines that contain gs.apple.com, then reboot your computer.
If you still ahve a problem it is likely that your antivirus or firewall is blocking access to Apple's activation servers.

HT1365 How can I get my iPhone 4 to update my updates from my app store of it keeps telling me error 3150 or it tell me to refresh the page after updates and the updates are still there asking me to update them again

How can I get my iPhone 4 to update my updates from my app store of it keeps telling me error 3150 or it tell me to refresh the page after updates and the updates are still there asking me to update them again?

Make sure iTunes on the computer is logged into the account on the phone.
Plug the iPhone in.
In the popup window warning about wiping your phone, hit cancel.
In the left pane of iTunes, the phone icon should be there.
Right click on it, select transfer purchases.
Note: this will only transfer music bought from iTunes. Not mp3's from amazon or ripped from CD's.

TFTP 'configuration update' from 5508 WLC fails stating reason as '%Error: Config file transfer failed – Unknown error –refer to log'

Dear Experts,
I have two WLCs and other management devices as part of same subnet. I am able to upload ‘configs’ from all the devices on to my TFTP server. However when I am attempting to do the same from one of my WLC, it is failing consistently stating error message as:
‘%Error: Config file transfer failed – Unknown error –refer to log
Has anyone else too faced the same issue and how would we overcome this? Any specific debug that could help get more details on it?
Though the error message says, refer to log but still I don’t see anything that gets reflected in ‘Monitor logs’ which is related to ‘configuration file’ upload failure.
WLC code: 7.4.100.0
PFA as the error snippet.
Thanks and Regards,
Adnan

Hi Kaneswaran,
Just a soft reboot helped me solved the problem :). Still I am on 7.4 and facing no issues after this.
Apologies for coming too late to respond. Getting a down time window was not that easy and so was much delayed to try soft reload. I am still on 7.4 and facing no issue.
Glad that in your case it starting working all of a sudden. Could you please verify from 'show tech-support' to confirm if by chance your WLC had undergone any crash that could have caused the WLC to reload and thus accidently fixing the issue :)
Best Regards,
Muhammed Adnan

These errors typically occur when security software interferes with the restore and update process. Use the steps to troubleshoot security software issues to resolve this issue. In rare cases, these errors may be a hardware issue. If the errors persist on another computer, the device may need service.
Also, check your hosts file to verify that it's not blocking iTunes from communicating with the update server. See the steps under the heading "Blocked by configuration (Mac OS X / Windows) > Rebuild network information > Mac OS X > The hosts file may also be blocking the iTunes Store." If you have software used to perform unauthorized modifications to the iOS device, uninstall this software prior to editing the hosts file to prevent that software from automatically modifying the hosts file again on restart.

TS2771 I'm trying to update my ipod touch and it gives me an unknown error. -1, i tried to reset.

I'm trying to update my ipod touch and it gives me an unknown error. -1, i tried to reset. Someone told me there is a reset option on the status screen on itunes, couldn't find that. so i just held to 2 buttons until apple showed up.

Errors when updating leads to corrupt system files and this may be your problem. If you're using windows, connect your device to PC and run any third party app like Syncios. If it detects, you maybe in luck and try to back-up your data if possible. I hope that it won't and if doesn't, there is no other way to recover files. You should be restoring with iTunes and all data will be erased, or else your device may become unusable.

If the above Support Article does not resolve it... then you have a problem.
Perhaps a Visit to an Apple Store or AASP (Authorized Apple Service Provider) is required..
Be sure to make an appointment first...
Note:
That error message may be indicative of the Device being Hacked / jailbroken.... If this is the case then you are on your own.
Unauthorized modification of iOS...

I cannot seem to load raw images into LR 2.5. I've been using this for years. I always load from memory card, but it gives me an unknown error message. I tried to load from camera, hard drive, & external drive and still will not work. I checked import

I cannot seem to load raw images into LR 2.5. I've been using this for years. I always load from memory card, but it gives me an unknown error message. I tried to load from camera, hard drive, & external drive and still will not work. I checked import menu and nothing has changed. I loaded the photos onto my tablet and images are fine, so do not feel it is the memory card. Any thoughts?

The error message probably said "unsupported or damaged"
The T3 requires Lightroom 3.4.1 or later. You can either upgrade to a more current version of Lightroom (version 5.6 is the most recent) or you can use the free Adobe DNG Converter to convert the RAWs to DNG, which should import into Lightroom properly.

In using it, I found out other's have had this issue and it likely means you have a 3G iPad? If you do, go into settings and turn off cellular data, then try to update again and you should be OK........

I get the same error (although in Dutch ;-)).
