Error whilst trying to restore iphone 5

iphone error 21 whilst trying to restore iphone a number of times.
HELP

Hello, _sara. 
Thank you for visiting Apple Support Communities.
Here are the steps I would recommend going through for error 21.
Check for hardware issues
Try to restore your iOS device two more times while connected with a cable, computer, and network you know are good. Also, confirm yoursecurity software and settings are allowing communication between your device and update servers. If you still see the alert when you update or restore, contact Apple support.
Common errors: 1, 10-47, 1002, 1011, 1012, 1014, 1000-1020.

  • TS4036 could not sign in server error when trying to restore iphone from icloud

    I am trying to restore my iPhone from an iCloud  backup.  I deleted everything on the phone per restore instructions. Connected to wireless on iPhone.  Logged on to my iCloud account.    Told the iPhone to restore from iCloud backup.  I keep getting ""could not sign in" server error OK.  I get this messge over and over.

    I actually noticed when I had this problem just now that my iPhone 4 wasn't on wif. Only connected to 3G even though I entered my network info and clicked connect. So I backed up a few steps and re selected to connect to wifi and it fixed my issue!

  • Getting "not enough space on iphone" error when trying to restore iPhone from latest backup in iTunes.

    Recently updated my iPhone 4 to iOS 6.1.3 and lost all of my contacts after doing so.  Tried to restore phone to latest backup performed in iTunes but I get an error message that tells me there's not enough space on my iPhone to perform the restoration.  The ultimate problem I'm trying to solve is the loss of my contacts so if there's another way to solve that please let me know. If restoring my phone is a proper solution please help me do so. 
    1.  How do I get my contacts back?
    2.  How do I restore my iPhone from latest backup when getting "not enough space" error?
    Please help!

    Contacts are not part of the backup. They are seperate and either you need to sync them with an email program such as outlook or use icloud mail,contacts, and calendars on the phone. Unless you did that then the contacts are gone.

  • "Unable to continue with activation" error when trying to restore iPhone 3G?

    So here's the sticky.
    My friends from the Middle East bought me an iPhone 3G. They had taken the SIM out of it.
    I connected it to my computer, and backed up all the photos. It was running 4.2.1 (the final version of iOS for 3G). I then downloaded 4.2.1 again from getiOS.net, hoping to rejuvenate the bogged down iPhone with a fresh restore. I connected it to iTunes, selected my downloaded iOS file, and proceeded with the restore.
    So it extracts the software fine, the progress bar also shows the restoration and verification going fine, but then when the iPhone reboots it shows a screen which sort of looks like the iTunes recovery mode screen (the wire connected with the iTunes icon) but it also has a popup saying "NO SIM CARD INSTALLED", and on my computer iTunes says, "We are unable to continue with your activation at this time. Please try again later."
    So where's my iOS gone?! What happened to my phone? How do I get it back to normal?
    Someone suggested putting the phone in actual recovery mode by holding down the home button and connecting it to the computer with iTunes on, but it just showed the restore option again and when I tried the restore again, the same problem happened.
    Please think of a solution guys. Is it because there is no SIM inside? Or maybe it's from a different region? Or what?

  • 3014 error while trying to restore iphone after upgrading to OS7

    I've spent my entire evening trying to recover my iphone 4S. I installed all the latest patches to MS Windows XP earlier in the evening, and then ran the update for iTunes. It failed part way through with the 3014 error.
    I shut down my firewall to ensure that wasn't the problem.
    Turned off my anti-virus software to ensure that wasn't getting in the way.
    I uninstalled iTunes, and reInstalled.
    I still getting the same error.
    I now have a useless iphone with no OS on it unless someone can help me get past this error. I am so frustrated by this it isn't funny. any assistance would be appreciated.

  • TS3694 Keep getting a 1015 error when trying to restore Iphone 3g

    Hi,  I have a problem with my old Iphone 3G, I upgraded to a Iphone 4 ages ago and just kept my old phone in a drawer, now I want to give it to my niece, so decided to plug into Itunes to reset it ready for her, it said it needed to update and download, it did that, but failed and said to restore it, but I keep getting 1015 error when it goes through the restore.
    Any ideas and options other than going to Genious Bar ?

    error usually means you have a jailbroken or a modified iphone.

  • HT201263 Elusive connection error whilst trying to restore 2nd Gen iPod Touch device (iOS 4.2) via iTunes

    Hi.
    It's been a while since I've updated my iPod, and now that I've tried to update it (from iOS 4.2), whenever I click the 'Check for new updates' [for my iPod] button, iTunes states that the latest version is already installed, which obviously is NOT the case.
    I am using the latest version of iTunes, and have already tried re-installing it.
    After attemping to update, the next logical step was to restore, despite losing some of my data this way, for I currently have no-choice but to update via a different system to my usual managing computer of my device(s). However, an unexplained error occured, and my iPod is stuck in recovery mode (displaying that 'connect to iTunes' image it shows at this point).
    Now, I've tried repeatedly to restore th iPod via iTunes, but it just won't work - as it is 'extracting software' (as indicated at the top of iTunes' window), it stops, giving a rather vague error: 'The iPod "iPod" cannot be restored at this time because the iPod software update server could not be contacted or is temporarily unavailable'.
    I have no idea why this occcurs repeatedly, as it is persistent to do so.
    I'd also like to confirm that my system is correctly connected to the internet at a speed that should be ample to install any required updates (furthermore, this error occurs after no-more-than 1 minute after attempting to restore the device)
    Thanks in advance
    ~mini.

    Thanks, but you don't happen to know anything else about this, do you?
    Also, I've now realised it was pointless trying to update my iPod, for I've now found-out that the 2G can't be updated past 4.2.1 (or something) anyway >_>

    I am getting error message when trying to restore iphone 3gs

    If this is your phone, it appears that you had either loaded the iOS 7 beta on it and it is now expired or you are not trying to restore the phone correctly. Did you attempt to update using something other than the standard procedure in iTunes? You cannot install a custom iOS file.
