If the STB's eMMC or NAND flash memory has been completely wiped, corrupted, or flashed with incompatible firmware, the device cannot load its secondary bootloader (u-boot). When this happens, the CPU falls back completely to its internal BootROM. If the BootROM loop is unstable or locked, the flashing software cannot get the response it needs to push the new bootloader. 3. Power Sequencing Issues
Ensure that the TX pin of your USB-to-TTL adapter connects to the RX pin on the STB board. Conversely, the RX pin of the adapter must connect to the TX pin on the STB.
:
The BootROM only listens for the flashing software's handshake for a fraction of a second after powering up. If you turn on the STB too early or too late after clicking "Connect" or "Burn" in your software, the synchronization window is missed. Step-by-Step Troubleshooting Guide

This error message typically appears when a or similar embedded device (often using Guoxin/GX chips) is in "BootROM" mode and waiting to receive a firmware file via a serial ( UART ) connection, but it is not getting a valid response from the computer .
The primary software instructions required to start the device (like U-Boot) are missing or corrupted.
