If you provide these details, I can give you the specific and pinout diagram for your device.
Typical bootROM baud rates:
Set the to 115200 (this is the industry standard for most Android-based STBs). Set Data bits to 8, Stop bits to 1, and Parity to None. 4. The "Power Cycle" Timing Bootrom Error Wait For Get Please Check Stb Uart Receive
The error message can be broken down into three critical technical components: Bootrom Error:

Mismatched speeds cause data corruption, resulting in dead silence on the UART lines.
Procedure usually is:
He swapped the cables. Nothing. He checked the baud rate. 115200. Standard. He pulsed the reset pin.
Some manufacturers disable UART access to prevent third-party firmware installation. Step-by-Step Troubleshooting Guide 1. Verify Your Hardware Wiring Nothing
