Bootloop is a cyclic reboot of the device, i.e., the phone tries to start the system but cannot do so. Most often, it occurs as a result of the wrong firmware of the smartphone. This condition is also called “brick”. Externally the phone looks fully working, but it’s impossible to start it. In rare cases, boot loops occur due to system failure, but this is an exception. You need to reboot the device to get rid of the problem, but only if the error has occurred.
In other cases, you can try to reinstall the firmware. You should also, if possible, enter the recovery menu and try to reset the device to the factory settings. And in general, if the phone goes into recovery, it’s quite possible to get it out of bootloop.
