Are you using a or a direct serial port? Which flashing software version are you currently using?
If you are trying to revive a dead set-top box (STB) like the or an STM32-based device, encountering the "Bootrom Error: Wait For Get" typically means your computer's upgrade tool is sending a request, but the device isn't acknowledging it through the serial connection.
If another utility (such as a 3D printer slicer, an Arduino IDE terminal, or a legacy modem manager) runs in the background, it can hijack incoming serial lines. Close all concurrent terminal processes, unplug the USB cord, reinsert it into a different physical port on your computer, and restart your flashing application as an Administrator.

Ensure the is set to "Even" or "None" based on your specific firmware instructions. 4. Master the Power-On Timing

A classic mistake where the transmitter is connected to the transmitter instead of the receiver.
The software is "talking" at a different speed than the hardware is "listening" (common speeds are 115200 or 921600).
