What can you do if you try everything but the apple does not appear on your iPhone screen? There is a special recovery mode - DFU. It is designed to restore iOS firmware if all your other attempts fail. Please be clear that this mode should only be used as a last resort, because if it is activated, all data from the iPhone will be lost.

To exit this mode, simply unplug the cable from the device and press HOME and POVER for ten seconds. After these manipulations iphone must reboot.


5. Help comes to the service center

If, despite all efforts, the iPhone could not revive on its own, we will have to turn to specialists for help. But remember that only if you treat it properly, your favorite gadget will serve you for many years.

If you find that your iPhone won't turn on, don't panic! It could simply be completely discharged and switched off. Accordingly, the iPhone needs to be charged for 15 minutes from the adapter or for 25 minutes from the computer, after which it will turn on - a battery with lightning inside will appear on the screen.

The smartphone refuses to charge the battery and does not make the characteristic charging sound. This problem is especially common on iPhone 4 and 4s. Most likely, the smartphone simply does not see a connection to a power source - a household outlet or a computer's USB port - due to a malfunction in iOS.

Sometimes, to restore the battery charging process, you just need to restart iOS. To do this, you need to connect your smartphone to a power outlet using a proprietary cable and hold down two buttons at the same time - Home and On/Off - until the iPhone restarts. As soon as the operating system loads, you will hear the sound of charging starting, and the animation of the smartphone’s battery level will also change.

Another reason for the lack of charge may be the use of a faulty or unsuitable cable. Cheap, uncertified cables often produce a slow battery charge, which can also appear as if the device is not charging. In this case, you need to wait 8-12 hours to fully charge the device if you don’t have another cable at hand.

Other reasons why iPhone 4 won't turn on or charge

  • Defective battery (requires battery replacement)
  • Dirty connector (Need to clean the connector)
  • Damage to the smartphone (diagnostics required at a service center)

Sometimes it happens that the logo “hangs” on the smartphone screen and the system does not reboot - in in this case The firmware could have crashed. In this case, a hard reboot of the system may help.

Everyone knows the high quality of Apple products, and the iPhone 4 is no exception. And yet, like any technology created by human hands, at times the iPhone can fail. This is especially worrying when you need to make an urgent call. In such cases, when the iPhone 4 does not turn on when you press the Power button, there is no need to immediately panic. Most problems can be fixed. Often such procedures can be carried out independently.

Causes of malfunctions

  • Software (the program crashed or the files were damaged by viruses).
  • Mechanical (there were mechanical damage or ordinary wear and tear).

In the case of mechanical failures, the problem is solved by replacing parts. There are often cases when you can do this yourself, at home. For example, when you need to replace the battery or glass.

If the malfunction is of a software nature, then even here you can do without the help of specialists. Let's consider the simplest cases.

The first reason that may come to mind is that the battery is completely discharged. There is not enough energy even to simply display the charge indicator on the display. Then you should connect your smartphone to your computer or network. At the end of 15 minutes (it may take more if connected to a PC), press the Power button without disconnecting from the network. After this, it will become obvious what the cause of the malfunction is: if the problem is only in the charge, then the device’s display will display an image of an empty battery with a lightning icon inside. It becomes clear that there is not enough energy to make calls and run programs. We wait several hours until the charge is fully recharged.

Software glitch

There are times when even after a full charge the iPhone 4 does not turn on. This may be due to software glitch. To resolve the situation, you can use a “hard reboot”. What is this procedure? To launch it, simultaneously press the Power and Home buttons and hold them until the Apple logo appears on the screen. operating system will reboot again, after which it becomes possible to use the device further.

Other reasons

So, we looked at two cases when you can do it on your own. Moreover, in the second case, all procedures will take only a few seconds. In the first case, it may take several hours to charge.

What to do if iPhone 4 does not turn on even after these procedures?

If after these procedures the situation has not changed, there may be a different problem. The following reasons why iPhone 4 does not turn on are possible:

  • the battery has failed (can be solved by replacing it at a service center or doing it yourself);
  • The power cable connector is clogged with dirt (you can carefully clean it yourself);
  • The USB cable or charger is faulty (in this case, nothing can be done with the old cable - it needs to be replaced);
  • short circuit due to moisture getting inside or mechanical damage to the device (you should not try to solve the problem yourself - it is better to contact a workshop);
  • voltage surges during charging caused damage to the microcircuits (this can happen if you charge the battery in a car);
  • manufacturing defect (replacement under warranty).

iPhone 4 is on fire, Apple does not turn on

Sometimes the device does not respond to actions from the owner, even when the “apple” lights up. This problem is one of the most common why iPhone 4 won't turn on. Possible reason It may be necessary to reflash the device. You can do this operation yourself. To do this, there is an iTunes service in DFU Mode, the screen must be turned off.

Press Shift + “Restore” (if you have Windows) or Alt + “Restore” (for Mac owners). The firmware is selected and the recovery procedure starts.

There may be situations where even after such a manual flashing the device does not start. Then you should contact qualified specialists. High-quality repairs will be carried out there, perhaps even before your eyes.

The most problematic situation is when the motherboard. In this case, it will need to be completely replaced, since the motherboard is a complex device consisting of a processor, RAM, various connectors and drives. The reason that can cause the board to fail can be either mechanical damage to the device or the ingress of liquid.

Wi-Fi problems

From time to time, owners receive complaints that the iPhone 4’s WiFi module does not turn on - the connection is periodically lost or the device does not want to connect at all. The cause may be either software glitches or mechanical failures. In the case when the Wi-Fi connection is periodically lost, a simple reset can help. The fact is that similar problems were noticed among users who switched to iOS 7.

And yet, there are more frequent cases when the problem lies not in the software, but in the hardware component. The best solution here would be to contact a service center.

For those who are determined to solve the problem on their own, an interesting way to solve this problem was suggested by one of the Internet users: heat the iPhone 4 with a simple household hairdryer. Heat until the display shows a critical temperature warning. Next, the author of the method advises turning off and turning on the device - according to him, Wi-Fi should work. But whether to use such a risky method or still take the expensive device to a specialist is up to you to decide. Advice from strangers is much less reliable than advice from professionals.
