HT4623 My iphone went died without power cord. When it connected to a power, an Apple logo keep blinking. When I tried to restore it by using Itune. it shows error 21 occurred. how to get my phone work again?
My iphone stopped working today. It only shows a blinking Apple logo when I connected it to a power. I tried to reboot it, but it didn't work. I followed a online suggestion to reboot by restore data from Itune. But when I did, Itune show a message that says it can't restore my iphone because an error 21 occurred.
Can anyone help me get my phone work again?

My iphone showed an app it recommended I download to update my phone, which I did.
My phone then switched off and showed a picture asking me to plug into Itunes, which I did. It then directed me to update my phone which took over 2 hours.
My phone still shows the diagram asking me to plug into itunes and it won't work! I have tried switching it off holding both the top and bottom buttons however the same picture remains and my phone is inoperable.
The error message on Itunes came up as error 3194 and guided me to this site.
I'd really appreciate any help in getting my phone working is anyone has experienced this before?
Thanks.

I was in the middle of the iOS 8 update and tried to turn my phone off (yes, I realize this was dumb) But what happened was it tried to reset. Now, my iphone 4s has the connect to itunes screen. I have tried to reset, recover, etc but I keep getting and error -51 message. Any ideas how I can get my phone working again? I am not worried about saving any info just having a phone to use!
Try a Hard Reset.....
Press and hold the Wake / Sleep button AND the Home button at the same time, keep them both pressed until the Apple Logo appears on the screen, it can take 10 or more seconds. Ignore the swipe to turn off message. -
I clicked on erase all content and setting.how do i get my phone working again
i clicked on erase all contents and setting, hoping it will just remove contacts and personal info since i was giving away the phone. now i just have an apple logo on a lit background. how do i get the phone working again.?
You were hoping to give the iPhone away right, which means you aren't worried about preserving data?
If that is the case, plug the iPhone into a computer with iTunes, if doesn't automatically ask if you want to restore the iPhone then we need to put the iPhone into forced recovery mode.
You can do that by keeping the iPhone plugged in and pressing and holding the sleep/wake button (the top button) and the home button (round one with the square in it) together until you see an apple logo. Once you see the apple logo let go off the sleep/wake button but keep holding the home button.
Once iTunes says it's detected an iPhone in recovery mode you can let go off the home button and then just restore the iPhone as new.
The added bonus of restoring the iPhone as new means you get rid of any software faults the iPhone may have. -

If you bought it used, many if not most of them are "jailbroken" and cannot be fixed. That's why they are sold. Unsuspecting buyers are generally out of luck.
Unauthorized modification of iOS can cause security vulnerabilities, instability, shortened battery life, and other issues
Inability to apply future software updates: Some unauthorized modifications have caused damage to iOS that is not repairable. This can result in the hacked iPhone, iPad, or iPod touch becoming permanently inoperable when a future Apple-supplied iOS update is installed.
... It is also important to note that unauthorized modification of iOS is a violation of the iOS end-user software license agreement and because of this, Apple may deny service for an iPhone, iPad, or iPod touch that has installed any unauthorized software. -

I just updated my phone and it is now stuck with usb cable and itunes logo and itunes on my computer says I have to restore. Can I get my phone working again without loosing my photos?
There is no other way than to plug into a computer to restore the phone. You can use another computer to do so, but in case you did not back up to iCloud your data and settings will be gone.
Follow this article to connect in recovery mode:

having attempted to upgrade to iO7 latest op system,the Ipad has stuck on the Terms & conditions page.It will not accept my agreement to terms and conditions or allow me to read them.
Ideas please on how to get it to work again,which will have to be via my lap top!
It sound as if the iPad is woking in the background-i.e.receiving eMails.Reset iPad and continue with update.
Hold down the Sleep/Wake button and the Home button at the same time for at least ten seconds, until the Apple logo appears
Note: Data will not be affected. -
Suddenly the apps I downloaded won't work. The screen "blinks" for a second as if the app is loading, and then returns to the home screen. All the apps that came with the iPod seem to be working fine. How to get them all working again?
First try a hard reset. To do this, press and hold both the Sleep/Wake and Home buttons together long enough for the Apple logo to appear.
If still no luck, try downloading another free app from the App Store.

Lastly, try to restore the iPod from a previous backup or restoring it to factory settings.

i have purchased itunes match but the cloud will not load on my ipad 4.it works on my iphone 5 & it originally worked on my ipad.the only music that will show up is stuff that i bought from the itunes store.any ideas on how to get this to work?
On the MBP, in iTunes, switch to Song view and enable the iCloud Status column by pulling down View > View options and selecting the option for "iCloud Status." Close the small window. Look for any tracks that have a status of "waiting." If you see several of them disable iTunes Match while holding down the Option key. Quit iTunes, wait a few seconds, then open it again and turn iTM back on. Let it compelete the scan. Wait until all tracks that are "waiting" have a status of either "matched" or "uploaded."
On the iPad, turn off iTunes Match then launch the Music app and let the contents clear out. Power cycle the iPad for good measure, then re-enable the service once all the tracks in iTunes have been processed. -
My iPhone 5 got wet and I dried it out for 3 days. Now when I charge it the apple logo keeps blinking. Phone is unresponsive, so I tried to restore it but got error code 21. Tried on another computer and got error code 2006. Any suggestions, or is it impossible to get it back?

Error 20, 21, 23, 26, 28, 29, 34, 36, 37, 40
These errors typically occur when security software interferes with the restore and update process. FollowTroubleshooting 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 iTunes: Advanced iTunes Store troubleshooting—follow 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.
Error 2000-2009 (2001, 2002, 2005, 2006, 2009, and so on)
If you experience this issue on a Mac, disconnect third-party devices, hubs, spare cables, displays, reset the SMC, and then try to restore. If you are using a Windows computer, remove all USB devices and spare cables other than your keyboard, mouse, and the device, restart the computer, and try to restore. If that does not resolve the issue, try the USB issue-resolution steps and articles listed for Error 1604 above. If the issue persists, it may be related to conflicting security software. If the errors persist on another computer and known-good USB cable, the device may need service.
If neither of those fix it, then it's toast. it will have to be replaced. -

How to get Iphoto to work again after Dropbox screwed it up?
I had never used Dropbox and opened an account primarily as a backup for photo storage. I moved my Iphoto library to the Dropbox folder. After a week of Dropbox churning tens of thousands of “files” without really uploading, I realized something was wrong and have since learned there is some disconnect in how Dropbox handles Iphoto. Something about symlinks, but I don’t need to know.
That’s not my question. I moved my Iphoto library back to Applications. All the photos appear still to be there, but I’ve lost functionality. I can’t advance from photo to photo within an “event,” or edit photos through Iphoto. The link to my external editor (PS Elements 10) also doesn’t work any more. I can’t send an individual photo to PS, or open a photo from the Iphoto library in PS.
Screw Dropbox, I won’t try to use it again. But how do I get Iphoto to work again like it used to? It seems like Iphoto has somehow been de-linked from the Iphoto library.
Thanks,
CaseI dragged and dropped the Iphoto library to the pictures folder and now the library appears in BOTH pictures and applications. (The Iphoto library icon in the Pictures folder has the little curved arrow indicating a link.) Should I have copied and pasted?
When I open Iphoto, it goes to one of the recent pictures in the library and the regular menu appears on the left (events, etc.). But I can't advance to different pictures within in the folder. I hit "edit" and none of the editing functions come up. I right-click on the photo to bring up the usual options like edit in external editor and nothing happens. As I said in my first e-mail, it links but has no functionality.
You say to do a restore. I've been backing up my Mac with My Book Studio and Time Machine, but never tried to restore from the My Book. The last backup was a month or so ago. Is that the kind of restore you're talking about? Can I just restore Iphoto (and iphoto library?) without messing with everything else?
Thanks for your help.

my i phnoe4s not working. when i connect to charger apple logo keeps blinking
Hello abuwafi,
The troubleshooting steps detailed below can help get your iPhone back into working order.
If your battery doesn't charge, or if your device shows a low-battery image, black screen, or "accessory not supported" alert, follow these steps.
Inspect the connector at the bottom of the phone:
Make sure that there are no bent pins in the connector.
Make sure that the connector is free from debris.
If there are bent pins or debris, please contact Apple Support.
Otherwise, continue troubleshooting.
Make sure that the outlet you're using works.
Make sure that the Apple USB cable and Apple USB power adapter work.
Plug the device in to power and let it charge until your device turns on. This could take between 10 and 30 minutes. If you don't have an Apple USB power adapter, try connecting to a computer's high-power USB 2.0 port (not a keyboard). The computer must be on.
If the device still exhibits an issue, try turning your device off and then on again while connected to power.
If the issue persists, please contact Apple Support.
