Bootloop is the screen that appears when your phone enters a boot loop. This usually happens if you install an update and it was not compatible with your device, or there were errors in installing the software onto your hardware. The Android logo will appear on this screen for about five seconds before being replaced by either a blank black screen or another Android icon as though nothing happened.
A hard reset may fix this problem, but only temporarily because once the device reboots again, it will enter into a boot loop all over again without any change to its internal memory.
If you’ve tried everything from clearing cache files to updating firmware & drivers but still can’t get out of a reboot cycle then most likely something has gone wrong with the hardware.
