Bootrom mode only opens for a split second when a device receives power. If you turn on the STB too early, it skips the bootrom and tries to boot a corrupted Android OS.

The error message "wait for get please check stb uart receive google" is a specific type of bootrom error. This message typically indicates that the device is having trouble communicating with the Google bootloader or is unable to receive data from the UART (Universal Asynchronous Receiver-Transmitter) interface.

When an embedded device or STB boots into a flashing or restoration mode, its internal BootROM runs a small software sequence. It opens up its hardware UART ports and waits for a specific byte configuration—often a GET command (such as 0x7F used in common microcontrollers)—from an external software flasher.

Fixing this requires re-flashing the firmware. Because the screen is frozen, you cannot use the settings menu. Phase 1: Basic Troubleshooting (Try First)

This error usually indicates that the STB is not responding to the computer's request to begin the data transfer.

Verify that the TX (Transmit) pin on your cable is connected to the RX (Receive) pin on the STB, and vice-versa. Ensure a solid connection between the devices.

The STB is not receiving data properly on its RX (Receive) pin from the computer. 2. Preliminary Requirements To fix this, you must have the following:

Loads the operating system (Android/Linux).

The STB is waiting for a command/firmware packet (a "Get" command) from the flashing software.

Open your upgrade tool (e.g., GXDownloader ) and ensure the matches your serial cable.

: Unplug any extra USB cables, external sensors, or HDMI cords attached to the STB. These peripherals can inject noise onto the main power rail or tie up the hardware serial bus.

Several issues can lead to this error. These can be broadly grouped into a few categories.

Your computer does not recognize the USB-to-UART bridge (like CH340, CP210x, or PL2303).
