Release the short circuit after 1 second. This actions blocks the chip from reading the corrupted local boot signatures, forcing the underlying BootROM to open up a clean serial or USB channel for recovery. 4. Hardware Verification Checklist

This error typically appears during or boot recovery on devices using Amlogic or Rockchip SoCs (e.g., Google Chromecast with Google TV, ONN Android TV boxes, Xiaomi Mi Box). It originates from the BootROM – the first code executed by the CPU – and indicates a communication failure over UART (Universal Asynchronous Receiver-Transmitter) between the host PC and the target device’s bootloader. Release the short circuit after 1 second

The BootROM protocol requires the computer to send data before the STB turns on. Avoid using USB hubs; connect the UART adapter

Avoid using USB hubs; connect the UART adapter directly to a USB port on your PC motherboard. : Avoid using USB hubs

Plug your USB-to-TTL adapter directly into a motherboard port (prefer USB 2.0 ports over USB 3.0, as they offer better legacy serial stability).
