Placing your device into recovery (DFU) mode:
Follow these steps to place your iOS device into recovery mode. If your iOS device is already in recovery mode, you can proceed immediately to step 6.
1. Disconnect the USB cable from the iPhone, iPad, or iPod touch, but leave the
other end of the cable connected to your computer's USB port.
2. Turn off the device: Press and hold the Sleep/Wake button for a few seconds
until the red slider appears, then slide the slider. Wait for the device to turn off.
* If you cannot turn off the device using the slider, press and hold the
Sleep/Wake and Home buttons at the same time. When the device turns off,
release the Sleep/Wake and Home buttons.
3. While pressing and holding the Home button, reconnect the USB cable to the
device. The device should turn on. Note: If you see the battery charge warning,
let the device charge for at least ten minutes to ensure that the battery has some
charge, and then start with step 2 again.
4. Continue holding the Home button until you see the "Connect to iTunes" screen.
When this screen appears you can release the Home button:
5. If necessary, open iTunes. You should see the following "recovery mode" alert:
6. Use iTunes to restore the device.
If you don't see the "Connect to iTunes" screen, try these steps again. If you see the "Connect to iTunes" screen but the device does not appear in iTunes, see this article and its related links.
If you have a problem getting into recovery mode then try: RecBoot: Easy Way to Put iPhone into Recovery Mode.
Note: When using recovery mode, you can only restore the device. All user content on the device will be erased, but if you had previously synced with iTunes on this computer, you can restore from a previous backup. See this article for more information.
Try this information. It discusses closing and opening iTunes again while the phone is still connected, not the compter though.This error is often related to USB timing. Try changing USB ports, using a different dock connector to USB cable, and other available USB troubleshooting steps (troubleshooting USB connections. If you are using a dock, bypass it and connect directly to the white Apple USB dock connector cable. If the issue persists on a known-good computer, the device may need service.
If the issue is not resolved by USB isolation troubleshooting, and another computer is not available, try these steps to resolve the issue:
- Connect the device to iTunes, confirm that the device is in Recovery Mode. If it's not in Recovery Mode, put it into Recovery Mode.
- Restore and wait for the error.
- When prompted, click OK.
- Close and reopen iTunes while the device remains connected.
- The device should now be recognized in Recovery Mode again.
- Try to restore again.
If the steps above do not resolve the issue, try restoring using a known-good USB cable, computer, and network connection.
Ok I have tried to update my GF's iPhone 4 to iOS 7, however itunes crahed halfway through and it's stuck on update mode and the even bigger problem is that her sleep button doesn't work. I'm in the dog house and need help. iTunes won't display the iPhone on the side bar whilst it's in this update mode.
I posted it in some other similar threads today and have had three people reply that it worked for them too, and nobody so far saying it hasn't worked. And yes, everything was still on my iPad; contacts, web bookmarks, all photos, nothing was changed. It just didn't update to iOS 7. After I got it working again I just used wifi and upgraded to iOS 7 over the air with no problems, using it as I type this. If you're still stuck, trying this will not endanger anything at all on your device. Worth a try at least, and I'm guessing it'll work for you to recover lost data of iPhone stuck in recovery mode.
There are steps to get your iPhone out of recovery mode if your iPhone stuck in Recovery mode, and you can check it from website. However, you also look for some apps which can help you get out of it. It can be easy and save time to do this.
