  • "iPhone is disabled, connect to iTunes" AND "iTunes can not connect to the iPhone because it is locked with a password" error message on the phone and the computer! Help!

    So I recently had my password wrong too many times and my iPhone 4S locked out telling me "iPhone is disabled; Connect to iTunes'. And so I connected to iTunes and decided to restore my phone. I finished the process of restoration of the configuration of my phone, but ultimately, it was not even let me in the phone! Once AGAIN he said "iPhone is disabled; " Connect " to iTunes '. However, this time, this message appeared just when I turned on my phone with a black background. I didn't scan the screen for the error message is displayed (and there was no time to be shown). When I tried to connect to iTunes again as he asked, now it says "iTunes can not connect to the iPhone because it is locked with a password".

    So now, he said "iPhone is disabled; ' Connect to iTunes' on my iPhone 4S and ''iTunes can't connect to the iPhone because it is locked with a password ' on my computer. WHAT should I do?

    As described in step 2 of "Erase your device with iTunes" in this article, you will need to use the Recovery Mode.

    Recovery mode is described in this article as well.  You may try to go into recovery mode more than once to succeed.

  • Just send a question to the support site that I can NOT connect on my email account after auto update of 38.3.0, cannot connect to my account to check the issue!

    I just posted a question on the last update automatic 38.3.0 it is possible to log into different e-mail accounts in a profile, only the first e-mail account. My support mozilla account is linked to one of the email accounts that I can NOT connect to. Can't connect to this email account to check the issue. Your last 38.3.0 Thunderbird is useless because it is no longer possible to log in different e-mail accounts in a profile, and your support solution is useless because you need to connect to the e-mail account to check the issue.
    How to proceed?

    You can change your email associated with your media profile.
    I have 38.3.0 and I can access all my email accounts I suggest you try the initial tests:

    Start T-bird with disabled modules.
    If it works on your module is to blame and you need to activate one by one.

    Start your operating system in safe mode with active network.
    If it works probably your antivirus is blocking or delaying. (Or driver).

  • I can not connect to Messages or FaceTime on my iPad

    I can't log into Messages or FaceTime on my iPad.

    I can connect in iCloud with my Apple but not Messagess or FaceTime.

    I've updated to 9.3.4.

    I recently received hundreds of emails from some Asian spammer all at once. I think that my message of account has been hacked or something. I tried to connect to remove them, but I can not connect now.

    I tried restarting and also did a reset a deletion and restoration, but nothing seems to work.

    I also rest my Apple ID several times with new passwords etc, but nothing works.

    SUggestions?

    Hello, Randy Burleson1,.

    Thank you for using communities of Apple Support.

    If I understand your message that you are not able to connect to iMessage or FaceTime on iPad Air. I like to use iMessage and FaceTime myself, so I want to help you as best I can to solve these issues. I recommend first of all, by ensuring that your Apple ID works correctly. To do this try logging on to appleid.apple.com from your browser.

    If you succeed, then on your iPhone go to settings and Messages. Scroll down and click on the section titled send / receive. If you are connected to the iMessage you will see the words Apple ID and email address. Type your address email Apple ID, click Disconnect.

    Once out of the faucet, use your Apple ID with iMessage and enter your e-mail address Apple ID and password.

    Repeat the same steps with FaceTime.

    If you receive error messages, please respond and let us know what you receive error messages.

    Best regards

  • I can not connect on my site to school more since I've updated my firefox to 34.0.5.

    I can not connect on my site to school more since I've updated my firefox to 34.0.5. I deleted the cert8.db and still have the same problem. Help, please!
    Here is the error: unable to connect safely
    Firefox cannot guarantee the security of your data on my.saintleo.edu , because it uses SSLv3, a broken security protocol.
    Advanced information: ssl_error_no_cypher_overlap

    One possibility is to use this extension to activate SSL3 temporarily only for a Web site that needs SSL3.

    Since the update to El capitan OSX 10.11.4 on my Macbook Pro (2012) I can not connect to the app store - ideas? Im not geek so please be gentle!

    Try restarting mode without failure. To restart in safe mode, restart the computer and press on and hold down the SHIFT key until the Apple icon appears. The computer starts more slowly than usual because the disk utility checks the drive. After getting on the desktop launch the App store and try to connect. Successful or not, once you're done, restart normally to exit safe mode.
