Firmware is a type of software that is embedded in a device's hardware. It acts as a bridge between the device's hardware and software, controlling the device's functions and operations. Firmware is typically stored in non-volatile memory, such as flash memory, and is designed to be updated periodically to ensure that the device remains secure, efficient, and functional.

If you are experiencing the issues above, installing fresh firmware is your best solution. Follow these steps carefully.
