Improperly installed USB Serial or Amlogic/Rockchip drivers on the computer.
. It means the "bootloader" is waiting for data from the computer but isn't receiving any signal through the UART (serial) port. Core Troubleshooting Steps Bootrom Error Wait For Get Please Check Stb Uart Receive
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.
The flashing tool is pointing to the wrong hardware port. It means the "bootloader" is waiting for data
Reinstall the or Rockchip USB drivers. 3. Refine the Shorting Procedure
: The RS232-to-USB adapter driver may be incorrectly installed or incompatible with your operating system. Incorrect Chip Type The flashing tool is pointing to the wrong hardware port
The error essentially indicates that the device's BootROM is waiting for a specific "GET" command, but that command is not arriving correctly. The solution requires a systematic approach to check your UART connection and identify whether the problem is software-related (wrong settings or files) or a hardware failure.
If the connection fails, repeat the process but press the physical hardware reset button on the board instead of pulling the power plug. 3. Adjust Software and Driver Profiles
This error message typically appears in the context of set-top boxes (STBs), embedded Linux systems, or devices with Broadcom or similar chipsets. It indicates a bootrom-level issue where the device is waiting for a specific signal or data over UART but isn’t receiving it.
