Why cant i restore my iphone and why does it keep turning off and on by itself
hello all
i just would like to know why my phone keeps turning off and on by itself
and why i cant i restore it on itunes
many thanks
alWhat worked for me, is going to the camera app, switch to video, turn on flash, and record. Let the phone record for about 10 minutes. (your phone will probably keep reseting itself) but that is okay, let it reset, and go back the the camera app and repeat. what you are supposed to do is let the phone sit there and wait for the back to feel sort of hot. stop recording at about 8 minutes and plug your phone into itunes, it should be charging, and once you do so you can then set your phone into DFU mode. This might not help you, or it will. I just fixed my iphone today, that had the same problem as you. so keep trying and it will come back to normal again! Cheers!

KarmaZangpoThe Basic Troubleshooting Steps are:
Restart... Reset... Restore from Backup... Restore as New...
Restart / Reset
http://support.apple.com/kb/ht1430
Backing up, Updating and Restoring

Can anyone help me keep my volume from turning on and off automatically?
Hi Friend,
I have faced this issue yesterday, but just for one app. Then I went to Notifications Center, turn all the settings of that app to off then turn it on again. Rebooth the device (press and hold Home and Sleep button simultaneally until turns off the device and appears the Apple logo), then everything works at a glance.
Hole it helps -

If you don't already have a current backup, you must back up your data, if possible, before you take the above step. You may be able to back up, even if the system isn't bootable. Ask if you need guidance. -
My iphone 4s turns off and restarts itself a few seconds or minutes after when I establish a FaceTime call. I've tried "Restore iPhone" from iTunes but the same thing keeps happening. Any solution?
Settings > General > Reset > Reset Network Settings
Also, if this only happens with one Wi-Fi network, power cycle that Wi-Fi router.
Basic troubleshooting from the User's Guide is reset, restart, restore (first from backup then as new). Try each of these in order. -
Why does my nano keep turning off and on when it is connected to my computer?
When i connect my nano to my computer the nano says that it is connected and nothing happens in Itunes. Then when the nano keeps turning off and on while it is plugged into my computer. What can i do to make itunes recognize my nano so i can add new music?
Please try the following:
Move System Configuration Files
(Note: You will have to reestablish your network connections settings.)
Go to /Library/Preferences
Move the SystemConfiguration folder to the desktop.
Restart your Mac. (Note: OS X will rebuild the files that are now sitting on your desktop. If this doesn't resolve the issue, you can move the folder back to it's original location.) -
My Ipad display is stuck on portrait mode. I tried the toggle switch, turning off and restart and just now backed up into Itunes and restored and still is stuck on portrait mode and it won't flip to landscape mode. Is this a hardware problem?
Has lock rotation been accidentally enabled within the control centre? If you swipe up the screen is there a circle with a lock symbol & if so is is greyed out or white - if white it is enabled.

DO NOT RELEASE BUTTON until you see picture of iTunes and plug
5. Release Home button.
ON COMPUTER
6. iTunes has detected iPad in recovery mode. You must restore this iPad before it can be used with iTunes.
7. Select "Restore iPad"...
Note:
1. Data will be lost if you do not have backup
2. You must follow step 1 to step 4 VERY CLOSELY. -
My ipod touch will not charge or register in itunes. It keeps turning off and then shows the apple logo. I have tried holding down the button and plugging it in. It will show the red battery for a second and then turn off? Any other suggestions?
I have checked for problems with the connections, but from what i can see with the naked eye, nothing appears abnormal. It is very strange, and very sudden. It just stopped in the middle of a charge. The apple store is my next step. I just wanted to see if anyone on here had some extremely eye-opening solution or check. thanks though!
I'm also within warranty, so it's not a huge problem. -

How do I fix my iPhone 4 that's keeps turning off and on

Ok, so i just jailbroke, and my ipod was going into safe mode a lot on its own, so i searched online for a solution, and that was to find the problem cydia tweak i downloaded, one of the ways was to got into the mobilesubstrate settings and single out the tweak, so i turned everything off but one, then my ipod shut off, and now it keeps turning off and on non stop, but never goes to the lockscreen, and the time for this startup and shutdown is prolonged! please Help!!! i tried to restore with itunes but it keeps turning on and off!
Jailbreaking voids the Apple warranty and also means that you will not get any support from Apple, including from this Apple forum. Jailbreaking can't be discussed in this Apple forum.

My iphone keeps turning off and powers itself again
my iphone keeps turning off and powers itself again
Hello dantecruso,
Thanks for using Apple Support Communities.
There are some troubleshooting steps I'd like you to follow in the article below in order to resolve this issue you're experiencing.
Will not turn on, will not turn on unless connected to power, or unexpected power off
Verify that the Sleep/Wake button functions. If it does not function, inspect it for signs of damage. If the button is damaged or is not functioning when pressed, seek service.
Check if a Liquid Contact Indicator (LCI) is activated or there are signs of corrosion. Learn about LCIs and corrosion.
Connect the iPhone to the iPhone's USB power adapter and let it charge for at least ten minutes.
After at least 30 minutes, if:
The home screen appears: The iPhone should be working. Update to the latest version of iOS if necessary. Continue charging it until it is completely charged and you see this battery icon in the upper-right corner of the screen Then unplug the phone from power. If it immediately turns off, seek service.
The low-battery image appears, even after the phone has charged for at least 20 minutes: See "iPhone displays the low-battery image and is unresponsive" symptom in this article.
Something other than the Home screen or Low Battery image appears, continue with this article for further troubleshooting steps.
If the iPhone did not turn on, reset it while connected to the iPhone USB power adapter.
If the display turns on, go to step 4.
If the display remains black, go to next step.
Connect the iPhone to a computer and open iTunes. If iTunes recognizes the iPhone and indicates that it is in recovery mode, attempt to restore the iPhone. If the iPhone doesn't appear in iTunes or if you have difficulties in restoring the iPhone, see this article for further assistance.
If restoring the iPhone resolved the issue, go to step 4. If restoring the iPhone did not solve the issue, seek service.
