I donnt why my iphone is not working. I can not turn on my phone.

I do not why my iphone 4 is not working. also I can not turn on it. please help me. Thank you

Meaning that you cannot restart or reset the phone? If you haven't tried already, try both options.
Otherwise, you can do a backup & restore, or even a restore as new (only after a successful backup).
If the issue persists, then look at a replacement. Either it will be a hardware defect (free if within warranty), or physical damage ($49 with AppleCare Plus, $149 without it.)

If you're not a registered developer, it means you've stolen Apple's software. Now you come to an Apple forum and ask for help? You're lucky you're not being prosecuted!
You can receive no help for stolen software here. Enjoy your iBrick.

Here is what worked for me:
My usb hub, being usb2, was too fast. I moved the wire to a usb port directory on my pc. That is a usb1 port which is slow enough to run your snyc.

Adobe pdf plug in for firefox, 10.1.4 version, does not work but can not update to new version, why?

Adobe pdf plug in does not work, when I tried to update following message appeared, "Adobe Reader 9.5.1 and lower has been blocked for your protection", how to solve this problem?

Could you review/adjust your preference for which program opens PDFs? I'm not sure how that drop-list behaves when there are multiple Adobe plugins. You might need to physically remove an old plugin file or two to make sure Firefox is not trying to use the old one.
* [[Use the Adobe Reader plugin to view or download PDF files]] <br>
''Edit: actually this article describe how to use the Options dialog Applications section to review/change the setting: [[How to disable the built-in PDF viewer and use another viewer]]''.
* C:\Program Files (x86)\Mozilla Firefox\Plugins (only one want nppdf32.dll here)
* In regedit.exe, check the following key for the source of obsolete plugins: HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\MozillaPlugins
Both the file that stores download handling preferences, and the file which registers plugins, can be renamed and Firefox will regenerate them, so those remains options for further actions as well.

HT4528 Buttons / Apps not working.. can't turn off

I have iphone 4. My soft button stopped working about a week ago.. so i enabled the icon that allows you to use the home button from the screen. Now my top hard button wont work. My phone will not turn off.. either buttons work and my apps wont open.

Try:
- iOS: Not responding or does not turn on
- Also try DFU mode after try recovery mode
How to put iPod touch / iPhone into DFU mode « Karthik's scribblings
- If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.
- Try on another computer
- If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

Please, help .. return not working. string can not be resolved to a variabl

Greetings..
I am writing a Java code that encrypt a String using DES. After encryption, I want to return the String, but I get error that says: variable can not be resolved. Please, help me to find out what is the problem ?? Thanks in advance.
Here is the code:
import javax.crypto.*;
import java.security.*;
public class Client {
     public String DESEncrypt(String cardnum)
          try{
          //create cipher object for DES
          Cipher c=Cipher.getInstance("DES");
          // craete the symmetric key for DES
          KeyGenerator kg=KeyGenerator.getInstance("DES");
          Key key=kg.generateKey();
          // DO the ecryption steps then display the result
          c.init(Cipher.ENCRYPT_MODE, key);
          //Dofinal accepts byts only. Thats why we use getbytes method.
          byte[] cardNoBytes=cardnum.getBytes("UTF8");
          //get the encrypted bytes
          byte[] encryptedCardNoBytes=c.doFinal(cardNoBytes);
          //convert bytes to string
          String cardNoString=new String(encryptedCardNoBytes);
          } catch(Exception e){ System.out.print("Error");
          return cardNoString;
     } //end the DESEncrypt method
public static void main (String[] args) {
try{
     Client cl=new Client();
     String x2=cl.DESEncrypt("123");
     System.out.println("The Encrypted text using DES is: " + x2+'\n');
} catch(Exception e){ System.out.print("Error");
}//end main
}

Next time, paste in the exact, complete error message and indicate clearly exactly which line is causing it.
Your problem is that you declare cardNoString inside the try block, but you try to return it outside. Local variables only exist in the narrowest block in which they're declared. Once you exit try, that variable does not exist.
You also have a logical problem. If an error occurs, you're just printing out :"Error", but you're not actually handling it. You're going on as if everything is fine. Catching an exception doesn't fix the error. If you can't fix it, don't catch it.
What do you think your method will return if an exception occurs before you set cardNoString? What do you think it will do to the caller to have some arbitrary, meaningless value returned when he thinks everything went fine and he got a valid result?

After ios 7 update, my find my friends 'alert sound' does not work. Can I turn it back on?

My camera is not working I can not take photos, use the recorder or even I can not use the facetime's video mode. Is there anybody that can have the same problem and knows the solution?

Please answer as soon as possible.

Have you tried a rest or hard reset?
Hold your power button and your home button for about 15 seconds until you see the apple logo.
Ignore the power slider when you see it.

Hello Jesslb23,
Thanks for using Apple Support Communities.
For more information on this, take a look at:
iOS: Troubleshooting Messages
http://support.apple.com/kb/ts2755
To resolve issues with sending and receiving iMessages, follow these steps first
Check iMessage system status for current service issues.
Go to Settings > Messages > Send & Receive and make sure that you have registered iMessage with your phone number or Apple ID and that you have selected iMessage for use. Learn more about troubleshooting iMessage registration if the phone number or Apple ID isn't available for use.
Open Safari and navigate to www.apple.com to verify data connectivity. Learn more about troubleshootingcellular data or a Wi-Fi connection if a data connection isn't available.
iMessage over cellular data might not be available while on a call. Only 3G and faster GSM networks support simultaneous data and voice calls. Learn more about which network your phone supports. Go to Settings > Wi-Fi and turn Wi-Fi on to use iMessage while on a call if your network doesn't support simultaneous data and voice calls.
Restart your device.
Tap Settings > General > Reset > Reset Network Settings on your iPhone.
If you are still unable to send or receive an iMessage, follow these steps
Make sure that the contact trying to message you isn't blocked in Settings > Messages > Blocked.
Verify that the contact you are attempting to send a message to is registered with iMessage.
If the issue occurs with a specific contact or contacts, back up or forward important messages and delete your current messaging threads with the contact. Create a new message to the contact and try again.
If the issue occurs with a specific contact or contacts, delete and re-create the contact in the Contacts application. Create a new message to the newly created contact and try again.
Back up and restore your device as new.
Best of luck,
Mario

Not with your current user id.
Far too much uneccesary information in your post, which only confuses things, a vast amount!
Let's start with iTunes.
Have you updated iTunes to 11.1.5, because the previous version did appear to have an issue about seeing iPods?
With iTunes 11.1.5 installed, look in Edit/Preferences/Devices, (or use the ALT key, followed by the E key and then the F key) and make sure that the box named Prevent iPods, iPhones and iPads from syncing automatically does not have a tick in the box.
Once you have doen those two things, check to see if the iPod is seen by iTunes.

By the way, what does IOS mean? (I thought IO stood for operating system, but am flummoxed by the S on the end.
Really?
OS stands for Operating System. (In computer speak, IO means Input/Output.)
iOS originally stood for iPhone Operating System, but it now refers to the iPod Touch and iPhone. The iPod Classic, which you have listed in your profile as your iPod, does not use iOS.
I assume that you have been listening to the Podcast in your iTunes on the computer as you cannot transfer it to your iPod. It's what I'd do.
