The device is in "wait" mode, expecting a firmware flash tool to send data via an RS232 (Serial) cable. Receive Full: on your adapter must go to RX (Receive) on the STB

: The communication speed (e.g., 115200) between the PC and the STB is not synchronized, leading to buffer overflows. : Double-check that your USB-to-TTL adapter’s TX goes
