iPhone 4S Error 4013 When Updating
Problem: Hello, I have a iPhone 4S that is stuck at error 4013 on iTunes while updating. Now the phone just keeps giving me this error on iTunes whenever I try to update & restore and the phone’s screen is stuck at itunes logo with USB cable. The sequence is, iTunes detects the phone and says that it needs to update and restore the phone, when I hit restore, it throws me 4013 error while waiting for the phone to restart and the phone goes back to iTunes & USB logo. Very frustrating as I never thought Apple updates had this problem (which now I see many people having the same problem). I did iOS update on my AT&T iphone 4S and it went smooth without a hitch and is working great, but not on my Verizon 4S. I went to verizon store and they said since it was stuck in that loop while trying to update which Apple has control on, I need to contact Apple store/service. I have never been to a apple store before and not sure how their support will be in this case.
Solution: Before going to an Apple store let’s try to troubleshoot the issue first and see if we can fix it on our end. The error 4013 occurs when the connection between your phone and iTunes suddenly gets disconnected during the update process. Having said that, there are various reasons why this occurs and could be due to a problem with the computer, USB cord, iTunes software, or the phone itself. Follow the steps below to resolve this issue.
- Install the latest version of iTunes.
- Restart your computer.
- Make sure your computer is up to date. If an update requires a restart, check for updates again after you restart.
- Restore using another USB cable.
- Restore your device on another computer.
If you are still seeing the error 4013 after this then it’s time to go to the Apple Store.
iPhone 4S Won’t Connect To PC
Problem: hello there, I have got a unique problem with my phone, I’ve been browsing different forums for a while and have not come across anyone with a similar problem. Every time I connect my phone to my pc it connects for 1 second and then disconnects and reconnects again for 1 second and this repeats constantly. The device connected noise keeps playing on loop because the device will connect for a second and then disconnect the next and reconnect after and so on. on my phone the battery will go green for charging and then normal and then charging as the phone connects and disconnects in seconds. my iTunes is up to date and so is my phone. I’ve tried with different usb cables and same results. I’ve stopped and restarted the apple mobile device and still no different. I’ve even been on device manager but the phone doesn’t stay connected long enough for it to appear on it to see if the drivers are updated. I am using windows 7. I greatly appreciate any help.
Solution: First check the connector port of your phone and PC if there are any dirt present. This may be causing the problem. If you find any then try taking it out with a toothpick. Follow the troubleshooting steps below.
- See if the cable connection at the device or computer has come loose or unplugged.
- Unplug the cable you’re using to connect your iOS device from the USB port on your computer, and then reconnect it. Then unplug it from your iOS device, and reconnect it.
- Remove any third-party battery packs or cases from the device and ensure that the USB cable is connected directly to the port on the device.
- If your Lightning or 30-pin cable is connected to a keyboard, display or USB hub, try plugging it directly into a USB port on the computer instead.
- Close any virtualization apps (such as Parallels or VMWare).
- These apps may interfere with your computer’s ability to communicate over USB if they aren’t properly configured, or up to date. If this resolves the issue, contact the developer of the app to see if an update is available.
- Restart your computer.
- Restart your iPhone, iPad, or iPod touch.
- If you’re using an accessory or third-party cable to connect your device, try using an Apple cable with the device instead.
- Update to the latest version of iTunes if you haven’t already.
- Disconnect other USB devices from your computer, except for your keyboard and mouse. Then, reconnect your iOS device. If the issue is resolved, reconnect the other USB devices one at a time. Make sure your iOS device is still recognized by the computer after adding back each device.
You might also want to try using a different computer to see if this issue is caused by your current computer.
iPhone 4S Does Not Charge
Problem: My iPhone 4s goes to Apple logo when I plug it in to charge, but it doesn’t charge. What should I do? Replace the charger, and the battery?
Solution: Replacing the battery of your phone is not an easy process since it isn’t user replaceable. What you need to do first is to eliminate any other possible causes first before concentrating on the battery. Follow the troubleshooting steps below to resolve this issue.
- For the quickest charge, connect your device to a power outlet using the USB cable that came with your device and an Apple USB power adapter.
- Connect your device to a USB port on your computer (not an external keyboard) using the USB cable that came with the device. Your computer must be on.
- Connect the device to an externally powered USB hub. For the quickest charge, you may need to disconnect other USB devices.
- Some third-party cables and accessories that aren’t Apple certified, or are FireWire equipped, may not charge your device properly. If you see either of the alerts below, the device may not charge: “This cable or accessory is not certified and may not work reliably with this iPhone.” “This accessory is not supported by this device.” Try another cable or accessory. If either of these alerts appear and nothing is connected to the dock connector, make sure that the dock connector is free of debris.
Aside from the steps outlines above you should also check the charging port of your phone and the charger to see if any dirt or debris are present. If you spot any then clean them out using a toothpick. You should also check if any pins are bent.
iPhone 4S Display Will Not Turn Off When Taking A Call
Problem: As I mention above, the screen of my phone doesn’t go black, when I put it to my ear. The buttons are active and depending how I hold the phone, my ear touching the buttons, the phone can go mute, the speaker can turn on. The screensaver does work, when I just lay my phone down. Thank you for some advice, to restore the black screen.
Solution: If your phone has any case or cover installed then try removing it first. This may be interfering with the proximity sensor of your phone. Make sure that the front part of your phone is clean and that no dirt is present. Perform the following steps below.
- Verify mute or speaker have not been activated, just prior to placing your ear over the receiver.
- While on a call hold your hand over the top third of the display, and verify that the screen is locked or goes to sleep.
- Try turning iPhone off and then on again.
If you are still having the same issue after performing all of the steps above then this might be a hardware problem most probably a faulty proximity sensor. Your best option is to bring your phone to an authorized service center for checking and repair.
iPhone 4S Slow and Unresponsive
Problem: Hello, I have a problem with my phone. I’ve found that it is unresponsive: pressing either the Sleep/Wake or Home buttons did nothing, alarms didn’t go off, the back was warm to the touch as if it was running something intense. It was necessary for me to hold down both buttons for awhile to force a reset – the Apple logo appeared and the phone rebooted. Once it was running again, everything seemed normal. I can’t see what was happening before the reset, since the reset seems to clear the system logs (visible in System Status and other apps). Is there a way to fix this?
Solution: If your phone gets slow or unresponsive then it is a sign that it is processing a lot of tasks or its memory is already maxed out. One quick way to resolve this issue is to do a factory reset.
- Make sure your computer is running the latest iTunes software
- Use iTunes to back up your device and transfer and sync any additional content to your computer.
- Turn off Find My iPhone in Settings > iCloud on your device to disable Activation Lock.
To factory reset your phone
- Connect your iOS device to your computer using the cable that came with it.
- Select your iPhone when it appears in iTunes. In the Summary pane, click the Restore button for your device.
- Click Restore again to confirm that you want to restore your device to factory settings and delete all data and content. iTunes will download the iOS software file and restore your iOS device.
- After your iOS device is restored to factory settings, it will restart, and you’ll see the “Slide to set up” welcome screen. Follow the steps in the iOS Setup Assistant. You can set up your device as new or using a previous backup. If your iOS device has cellular service, it will activate after you restore.
iPhone 4S Downgrading from iOS 7 to iOS 6
Problem: I have a 4S running on iOS 7 which I would like to downgrade to iOS 6. Do you know of the correct procedure to do this?
Solution: Unfortunately there is no official way for you to downgrade the operating system of your phone. Once you are on iOS 7 you cannot go back to iOS 6.
iPhone 4S Low Memory Error
Problem: I’ve noticed quite a lot of Low Memory error/diagnostics entries on my 4S ever since I upgraded to 7.1.x. Out of those transferred to the computer via iTunes, there are around 80 items for June, around 260 for July, and 252 for August so far. Is this something 4S on 7.1.2 has to live with?
Solution: These error messages are normal and happen when the apps takes up RAM faster than the phone can manage. If your phone is crashing or unresponsive then this is another story. One suggestion I can make if you are uncomfortable with this type of error message is to try uninstalling the apps that you don’t regularly use.
