The firmware on Android has crashed. What to do if the phone does not turn on?

Quite often, users of devices running Android encounter a problem when, after turning off the phone again, it simply stops turning on. This may be due to a number of reasons, which we will, of course, talk about. But, most importantly, here and now we will teach you things that will help save your smartphone from “eternal sleep” and tell you what to do in situations where the firmware on Android has completely crashed. Reasons why your smartphone won't turn on
Here, in a completely logical way, we can distinguish two reasons why your device does not turn on.

At first, the issue may be in the hardware of the smartphone. There is only one option here: take the phone to a technical service, where specialists will pronounce a verdict. It is quite possible that a broken part is easily replaceable (for example, a battery) and can be replaced with a working one.

Otherwise The problem may lie on the software side. This means that the device does not start due to an incorrectly installed operating system (aka firmware) or due to interference with system files, which is also fraught with consequences.

How to restore Android operation if the firmware has crashed?
If you are 100% sure that the problem is caused by the software not working, then you can try to fix everything yourself at your own peril and risk.

It is about full reset to factory settings. It is worth considering that all your data from your phone and SD card will be completely erased, so before performing this operation, make a backup copy of your files if necessary.

If after resetting the settings you see that it did not help, then you should change the firmware. Of course, you can do this with the help of the same specialists or personally.
As a summary, let us remind you that you are personally responsible for all your actions, so you should be very, very careful when resetting the settings and/or flashing Android.
