Causes of malfunction

iOS software updates are necessary for your device to work properly and productively. According to the law of programming, every software has at least one bug. The specialists who develop the program constantly "catch" bugs, eliminate them and improve the phone's OS to exclude arising and possible software failures.

But sometimes, the iPhone shuts down and doesn't boot up after an update. Do not immediately carry the gadget to the service center - try to run the recovery mode with your own hands instead. The reasons for such a problem can be the following:

  • The smartphone ran out of power because the update requires a lot of energy;
  • The memory chip has failed;
  • The power button broke when rebooting the device;
  • The binding to the location operator was removed;
  • The firmware is "broken" (firmware build and reset).

In some cases, you can try to solve the problem yourself without the help of specialists. To do this, use the recovery mode recommendations below.

How to restore the functionality of your smartphone

How to restore the functionality of your smartphone

If you have updated your Apple phone to the latest version of the OS, and it crashes and does not boot after the update, you should try to renew it with your efforts.

The process of iPhone recovery depends on the cause of the shutdown during the software update. Follow this guide:

  • First, try to put the phone on the charger (preferably use the original charger, as Apple products do not respond well to other accessories). Software updates can take quite a long time and, therefore, greatly drain the battery.
  • If the battery runs out during updates and the phone refuses to turn on, connect it to a power source for at least 24 hours. If a dead battery causes the problem, you won't get results sooner.
  • If the phone still does not turn on after 24 hours of charging, you can try resetting the gadget. A hard reset of the iPhone is the first procedure you should use. It is used if there are minor malfunctions.
The process of restoring an iPhone

You can use a hard reset if your phone doesn't turn on. To hard reset your phone, do the following:

  1. Press the "Home" button and the “Power” button at the top simultaneously.
  2. Hold the buttons in this position for 12-20 seconds.
  3. Wait till the Apple logo appears on the screen.

If the screen still doesn't turn on after you've updated your iPhone, chances are the locking problem lies in internal parts of the gadget or in the software where the reset occurred.

If you find out that your iPhone won't boot even after a hard reboot, you should not try to run the recovery process further. If a faulty chip causes the failure, only a professional technician can diagnose and repair the gadget to restore it.

The repair process consists of the following:

  • Diagnostics to determine the causes of why the phone does not turn on;
  • Conducting a software update;
  • Fault finding;
  • Deletion of damaged items;
  • Reflashing the smartphone if necessary;
  • Verification of the result.

Suppose a hard reset or charging the device while updating the OS didn't help you. In that case, you should seek help from a professional willing to provide inexpensive repair services. Self-disassembly and attempting to replace the original parts will only lead to more serious damage to your gadget.

If your iPhone does not turn on after an iOS update and attempts to restore the smartphone fail, you should contact an experienced technician. Make a request through Howly if your iPhone does not turn on, and specify the signs of failure and the model of the gadget. Specialists will leave their suggestions.
