If the computer's Device Manager points to an unassigned COM port, or if the USB-to-TTL serial adapter driver is corrupted, data will not transmit over the physical cable.
Before diving into the specifics of the error message, it's essential to understand what bootrom is. Bootrom, short for boot read-only memory, is a type of non-volatile memory that contains the initial boot loader or firmware for a device. It's the first piece of software that runs when a device powers on, responsible for initializing the hardware and loading the operating system.
Many Android TV boxes fail to connect via USB 3.0 (blue ports). Use a USB 2.0 port, typically located on the back of a desktop computer.
