If the ports aren't the issue, your computer likely doesn't have the correct driver to understand the Amlogic handshake.
Follow these steps in chronological order. You will need a USB-to-UART (TTL) adapter (e.g., FTDI FT232RL or CH340G), a computer with a serial terminal program (PuTTY, Tera Term, or screen on Linux/Mac), and basic soldering/alligator clip skills.
In some cases, this message appears briefly and then disappears as the device boots normally from NAND/eMMC. For example: Bootrom Error Wait For Get Please Check Stb Uart Receive
Bootrom Error Wait For Get Please Check Stb Uart Receive
Boot from NAND...
If booting continues successfully, you can ignore it. The message simply means the BootROM checked UART, found no incoming data, and moved to the next boot source.
The BootROM is waiting for a specific file (usually a bootloader or firmware header). You must send it using the correct protocol. Common methods: If the ports aren't the issue, your computer
Important: The file must be sent immediately after powering on the device. Some BootROMs wait only 2–5 seconds.
The "Bootrom Error Wait For Get Please Check Stb Uart Receive" message is essentially the device saying: “I’m ready to receive firmware over UART, but nothing is coming.” By carefully checking connections, serial settings, and sending the correct file at the right time, you can resolve this error and restore or unbrick your device. If booting continues successfully, you can ignore it
If you are trying to recover a bricked device, ensure you have the correct original firmware or bootloader image. A mismatched file will either be rejected or cause further issues.
Do you have a specific device model (e.g., Hi3716, Amlogic S905, BCM7252)? Leave a comment for targeted advice.
