    In your case your only solution is to restore it ( see http://support.apple.com/kb/HT1808 ) and you may need to force it into restore mode to do that.  This will wipe everything off it and reset it as new, without the passcode.  You can then redownload purchased content, buy unless you have a sync'd copy of your contacts and photo's they will be gone.

    Hi, to get your iPhone  4 back to normal, here're two ways for you.
    1.  Use Dr.Fone for iOS. The free trial version can fix iPhone screen of death. The free trial version can do that, you don't have to pay.
    Just download and install this software on your computer and connect your iPhone 4 to computer with a USB cable. When it detects your iPhone 4 is abnormal, click Restart the device to get your iPhone 4 to be normal.
    2. Use iTunes to fix it.
    Step 1. Make sure that the latest iTunes is installed on your computer.
    Step 2. Plug into a USB cable to connect your iPhone4 to computer.
    Step 3. Press and hold the Home button and the Sleep/Wake button at the same time for about 10s.
    Step 4. 10 seconds later, release the sleep/wake button. But continue to hold the home button until a message comes out, saying "iTunes has discovered an iPhone 4 in recovery mode, you must restore this iPhone before it can be used with iTunes".
    Step 5. Click your iPhone 4 in the left sidebar to show the device control panel on the right. Then, click Summary.
    Step 6. Go to Backups section and click Restore Backup.... In the drop-down list, choose a backup file and restore to your iPhone 4

  • My computer's hardrive went bad an I had to get a new one. Now my computer has nothing on it and I had to reinstall itunes and i have no music or anything. So now I cannot sync my ipod or anything. Is there anything i can do to get all of my stuff back?

    It has always been very basic to always maintain a backup copy of your computer for just such an occasion.
    Use your backup copy to put everything back.

  • TS3148 my computer has a lighting bolt and a hazard symbol on it and will not run anything

    Can someone help me know what to do in this situation. My computer has a lightining bolt and a hazard s ymbol on a grey screen and it will not reboot or do anything

    Reinstall OS X without erasing the drive
    Do the following:
    1. Repair the Hard Drive and Permissions
    Boot from your Snow Leopard Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list.  In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive.  If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
    If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
    2. Reinstall Snow Leopard
    If the drive is OK then quit DU and return to the installer.  Proceed with reinstalling OS X.  Note that the Snow Leopard installer will not erase your drive or disturb your files.  After installing a fresh copy of OS X the installer will move your Home folder, third-party applications, support items, and network preferences into the newly installed system.
    Download and install the Combo Updater for the version you prefer from support.apple.com/downloads/.

  • I updated my ipod touch 5th gen to iOS 8.2 and left it but when i got back it was in recovery mode with a red iTunes logo and i plugged it into my computer to reset my ipod and it wouldn't do it what do i do?

    I updated my ipod touch 5th gen to iOS 8.2 and left it but when I got back it was in recovery mode with a red iTunes logo and I plugged it into my computer to reset my ipod and it wouldn't do it what do I do?

    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 another cable       
    - 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.

  • My computer has become much slower and may have been infected.  Is there any course of action I can take in solving this problem?

    my computer has become much slower and may have been infected.  Is there any course of action I can take in solving this problem?

    If this started happening without your having made any changes and without a warning of low disk space, then it's likely that the startup drive, or some other hardware component, is failing. Back up all data immediately, then run Apple Diagnostics or the Apple Hardware Test.
    Even if the test is negative, you should make a "Genius" appointment at an Apple Store to have the machine tested more thoroughly.

  • So i have some open work from the night before on my computer and left it on, closed the top, the computer restarted it's self and lost all the work to what was added.....where can i find it....was it auto saved?

    so i have some open work from the night before on my computer and left it on, closed the top, the computer restarted it's self and lost all the work to what was added.....where can i find it....was it auto saved?

    If the application supported auto-save, yes, if not, then no.
    If you were creating a mail message, it might be in the drafts folder of the e-mail program.
    What evidence do you have the computer restarted itself?    Did the Apple logo come up?

    '''Try the Firefox SafeMode''' to see how it works there. <br />

  • My phone reset it self and says "active iphone"

    My iphone reset it self and once i unlocked it, it made me type in my apple id to activate it. The thing is i changed my apple id email awhile back so its a different email then what it says it is. Its the same apple id i just changed the email awhile ago. So would that change anything?
    once i type in my id & password it says "could not activate iphone: your iphone could not be activated because the activation server is temporarily unavaliable. Try connecting it to iTunes to activate it, or try again in a couple of minutes.

    So you have to manually update, (I had been getting over the air updates)

  • HELP! my mac has logged me out and now asking for a name and password?

    I was logged on shopping on top-shop online and suddenly the mac shut down.
    It seems it has reset its self! My icon has disappeared and its now asking  for a name and password.
    i have tried my log in but it is not working.
    Is there another way to reset the password?
    can i reset it to log back in what can i do?
    I have rebooted the computer several times but i dont know what to do!

    First, make sure caps lock is not on.
    Another reason why your password might not be recognized is that the keyboard layout (input source) has been switched without your realizing it. At the login screen, you can cycle through the available layouts by pressing the key combination   command-space or command-option-space. See this support article.
    If the user account is associated with an Apple ID, and you know the Apple ID password, then maybe the Apple ID can be used to reset your user account password.
    Otherwise*, start up in Recovery mode. When the OS X Utilities screen appears, select
    Utilities ▹ Terminal
    from the menu bar. In the window that opens, type this:
    res
    Press the tab key. The partial command you typed will automatically be completed to this:
    resetpassword
    Press return. A Reset Password window opens. Close the Terminal window to get it out of the way.
    Select your startup volume ("Macintosh HD," unless you gave it a different name) if not already selected.
    Select your username from the menu labeled Select the user account if not already selected.
    Follow the prompts to reset the password. It's safest to choose a password that includes only the characters a-z, A-Z, and 0-9.
    Select
     ▹ Restart
    from the menu bar.
    You should now be able to log in with the new password, but your Keychain will be reset (empty.) If you've forgotten the Keychain password (which is ordinarily the same as your login password), there's no way to recover it.
    *Note: If you've activated FileVault, this procedure doesn't apply. Follow instead these instructions.

    Guys, i am actually trying using a solution provided by the article shared by dominic23,
    It says "Another option is to get an ionizer to help the atmosphere in the workplace be more conductive and pull charges away from contact surfaces, including yourself."
    So in my home, we have such device that could clean the air using ion, and i am using it in my room...
    Result: BANG!!! The electric shock on my macbook has gone!! I don't really care about physics but somehow it works! You guys should give it a try.
    Thanks again dominic23
