Power on the STB. If you see the error message repeated, your UART receive path is working. If you see nothing, swap TX and RX.
Flashing utilities require precise synchronization with the chip's power-on cycle to catch the BootROM window before the main operating system boots up. Disconnect the power supply or power adapter from the STB.

This error message is the device's way of saying, "I am listening for instructions on the serial line, but I hear nothing." Why "Google Verified" Matters
This error typically happens when attempting to unbrick, recover, or upgrade a device built on popular chipsets like NationalChip (GX), Hisilicon, or MediaTek. Below is a complete guide to diagnosing and fixing this hardware and software connection issue. Understanding the Error Breakdown
