A bootloop refers to a situation where a device (such as a smartphone or a computer) gets stuck in a continuous loop of rebooting or restarting, unable to fully boot up to the operating system. This can happen due to various reasons such as software issues, firmware problems, hardware malfunctions, or incompatible system updates. Bootloops can be frustrating as they prevent the device from functioning normally and can sometimes lead to data loss if not addressed properly. Troubleshooting steps for fixing a bootloop may involve performing a factory reset, flashing the firmware, or seeking assistance from technical support.
