HT201210 iphone 4 has died. tried a restore but getting an error 21 - help please
looked at my phone tonight and noticed that it wasn't responding. Thought the battery was flat so put in on the charger. it then gave me a message suggesting that I needed to connect to itune - so i did.
Tried a 'restore' but got a error 21.
Phone is currently dead
Please help - need phone
iPhone error codes are often not very specific to the cause. But Error 21 can be due to faulty battery in some cases. So battery replacement could help. Here is Apple Guidance: http://support.apple.com/kb/TS3694#error21

I just got a new iPhone 4S and tried to restore but it didn't finished downloading all the apps, tried to reset and restore again, but it wouldn't start over. What can I do?

Check USB connections
If there’s an issue with the USB port, cable, dock, or hub, or if the device becomes disconnected during restore, try troubleshooting the USB connection, then troubleshooting your security software.
Common errors: 13, 14, 1600-1629, 1643-1650, 2000-2009, 4000, 4005, 4013, 4014, 4016, “invalid response”, and being prompted to restore again after a restore completes.
To narrow down the issue, you can also change up your hardware:
Use another USB cable.
Plug your cable into a different USB port on your computer.
Try a different dock connector (or no dock).
Add (or remove) a USB hub between your device and computer.
Connect your computer directly to your Internet source, with no routers, hubs, or switches.
If you see your error after changing your USB connections, continue to the next section to troubleshoot your hardware. -
I have unlocked my iPhone 3G with Vodafone via iTunes, but now the downloaded apps crash immediately when opened. I've tried a Restore, but this didn't help. I've also tried removing all apps and re-installing them, but they still don't work. Any ideas? Thanks.
yep, unfortunately can't reset without the passcode either.
With regards to doing a restore, do you mean:
open itunes on my computer
click on my device on the left
go to the device summary
click restore
it then asks if i want to back up before i restore (to which i say no)
then it asks me if i'm sure I want to restore to factory settings and that all of me media and data will be erased and replaced with the newest version ( to which I say yes)
then it takes about 90 mins to do this but when I look at my phone, everything is exactly the same.
Am I missing something? Obviously I'm technologically challenged, but I HAVE to get to the bottom of this! -
I have an ipod touch that continues to have a black screen with the white apple on it. It won't shut off and is completely frozen. This happened when we tried to restore it last night. Help please!!
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.
- If still not successful that indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

I start the SETUP IPHONE PROCESS.
I am told that I need to upgrade to new Iphone OS.
It takes 2 hours to download.
I get an error
I try to reconnect the iphone - GET MESSAGE that the phone is in recovery and needs to be restored.
I start restore - i get an error. I start again. It shows all the green bars as completed but then freezes. I restart the computer.
ITUNES tells me again that Iphone is in recovery and needs restore.
I start restore. I get a message: The Iphone could not be restored. An unknown error occured (14).
I don't know what to do.I have had this same problem, and you'll find out it will eventually work, but then after that your phone wont even start up and wont be able to connect to your computer! it's only allowing me to make Emergency Calls
This new update has really peeved me, i need my phone for work.
Try another computer, updating itunes, or different ports, restarting computer. Only thing i can think of sorry. -

Just synced my iphone 3GS and now many of my app's won't open on my phone. This was with version 4.3.2. I tried a reboot on my iphone but that didn't help. Any ideas?
this happened to me with my iPhone 4. I researched the problem and found this :
"The reason this happens is because every time a downloaded app is opened it checks for your itunes password for validation that you are authorized to open that app (as it may contain personal info). From time to time the iphone 'forgets' your itunes password. You can fix the missing password by syncing the iphone with itunes or downloading an app from the app store and entering your password that way.”
And to fix it, all I did was download a new app, or delete a current one, I used Facebook, and re-download it.
Hope this helps -
HT201210 iphone won't charge or restore, keep getting error message
Last night I plugged my iPhone 4 into the APPLE wall charger and it would not recognize it to charge it, I unplugged it and plugged my iPad into the same charger and it worked so it was clearly my phone. I called my service provider because I was going out of town today and it was already late at night. I was going to re-activate my old iPhone 3 until I could take it in and get it looked at....that was a nightmare....it's always a sad day when a consumer knows more about a product then the person selling them......she told me to take my sim card out of my iPhone 4 and just put it into my iPhone 3 and it would work, there was no need to call in....seriously??? They are TWO DIFFERENT cards that don't work in one another....if it was that simple would I have really called in the first place.....UGH! ANYWAYS..................so after she hooked up my old iPhone 3 to my husbands account and disconnected his iPhone 4S.....she is real swift.....I put my sim card in my husband's phone to get through the day! WIth my iPhone 4 only have 9% battery left I turned it off and left it over night. Then this morning while it was turned off I plugged it back into the same charger and the apple sign appeared.....so that would tell me that it's not the charging port that is the problem....except it still won't recognize the charger? I have done a reset...hold the home and power button at the same time with no luck, called apple and followed their instructions of holding the home button and plugging it into the USB port that is hooked to the computer to do a restore, it makes it through like it's going to restore and then I get the following message: The iPhone could not be restored. An unknown error occured (1604)
If anyone has any ideas please let me know.
Thanks!Hello tsugi1002,
It sounds like your iPhone 4S is not charging when plugged into your computer. I found an article with some steps that might help with this. I recommend reviewing the steps in the sections titled "Battery does not charge from the USB power adapter" and "Will not turn on, will not turn on unless connected to power, or unexpected power off" in the following article:

Hi,
My Autistic son dropped his ipad and now the screen is blank? The sound still works and I can hear the apps working but the screen is blank. The screen is not broken or chipped at all. I tried to restore it (as the Apple Store recognises the Ipad when I plug it into the computer) but the restore failed with an unknown error numbered 3194. Does anyone know if there is a quick fix for this or do I need to send it into an Apple Store for repairs? I live on a small island so taking it into a store isn't an option unfortunately, plus my non verbal Autistic son is VERY distressed, so any quick resolution to enable to screen to be visual again would be a massive help please.

Hey jestinsinclairr,
Thanks for using Apple Support Communities.
After reviewing your post, it sounds like you had one issue and then got a second trying to resolve the first. A frustrating situation for sure. The first article linked has what to do if it is not powering on unless plugged in. The second article addresses the error you are receiving when trying to restore.
