Do not connect the 3.3V or 5V power pin from your USB-to-TTL adapter to the STB if you are plugging the STB into its own wall adapter. Powering the board from two distinct sources simultaneously can damage the SoC or your PC’s USB port. 2. Match the Terminal Communication Settings
: Ensure the RX pin on the adapter goes to the TX pin on the device, and vice versa. STMicroelectronics Community Are you attempting to a specific brand of Android TV box or set-top box? Bootrom Error Wait For Get Please Check Stb Uart Receive
Open your terminal client (such as PuTTY, Tera Term, or SecureCRT).
: Check if there are any updates available for your STB's firmware or software. Manufacturers often release updates that fix known bugs. Do not connect the 3
By methodically working through this guide—starting with verifying the and using a high-quality data cable , and then moving to driver reinstallation, software downgrades, or even a hardware short if necessary—you have an excellent chance of bringing your "bricked" Android TV box back to life.
: Standard serial tools defaults to No Parity, 8 Data Bits, and 1 Stop Bit (8N1). However, certain platform BootROMs strictly require Even Parity to auto-negotiate. Change your software's serial port parameters to test this configuration. 3. Execute the Correct Power and Reset Timing
: The error occurs at the lowest level of the device's hardware initialization, before the main operating system or even the bootloader (like U-Boot) loads. Match the Terminal Communication Settings : Ensure the
Since the box is asking for a UART connection, you can often bypass the physical serial port by using a USB-to-USB Male-to-Male cable Get the Firmware
Connecting to the device's UART port can provide direct insight into what the BootROM is actually doing. When you connect a USB-to-UART adapter to the device's serial pins (typically located on a 4-pin header labeled RX, TX, GND, and sometimes VCC), you can monitor boot messages in real-time using a serial terminal. The BootROM typically communicates at .
Resolving this error requires methodically eliminating potential causes, starting with the simplest fixes and progressing to more advanced solutions. : Check if there are any updates available
Understanding this error requires a look at how your Set-Top Box (STB) communicates with your computer during the earliest stages of the power-on process. What Does This Error Actually Mean?
This paper investigates a boot-time error observed in certain embedded set-top box (STB) platforms, where the BootROM outputs: "bootrom error wait for get please check stb uart receive google" The error indicates a failure in the initial boot handshake over UART, specifically when expecting a specific trigger or handshake token (possibly related to a Google-developed secure boot or download protocol). We analyze root causes including corrupted boot media, incorrect UART configuration, or missing download handshake, and propose a systematic diagnostic and recovery procedure.
To help you get back to streaming, I can look up the specific fix for your device if you tell me: Brand and Model (e.g., X96 Max, Tanix TX6, MXQ Pro). Do you have a USB Male-to-Male cable Did this happen after a system update or out of the blue? I can provide the exact firmware link driver setup once I know your model!

Users typically encounter this error in several specific situations:
The software utility (such as HiTool, Putty, SecureCRT, or a proprietary vendor flasher) must match the precise expectations of the BootROM factory defaults.
