SER9 Pro (HX 370) BIOS

ALEX77

I am writing to report a technical issue with my SER9 Pro (HX 370) after updating the BIOS from version v103 to version v227.

Since the update, the power LED turns off completely in sleep mode instead of blinking, and it fails to illuminate after the system wakes up. I attempted to roll back to the previous BIOS version, but the process failed with a “Problem erasing flash” error.

Please provide the following assistance:

A new BIOS file that resolves the sleep mode LED issue, or a stable firmware file with a guide for a safe rollback.
Instructions to resolve the “Problem erasing flash” error during BIOS installation.

Device details:

Model: SER9 Pro (HX 370)
S/N: CHX375HH60040

Thank you very much. The problem is now resolved.
First, I believe I installed the wrong BIOS version on my PC.
Is there an updated BIOS version suitable for my system?
Additionally, would there be any compatibility issues if I upgrade to a Wi-Fi 6E or Wi-Fi 7 network card?

Hello there,

Thanks for your reply~

We are very glad to hear that your problem has been solved.

The lastest BIOS version of your machine should be the V227.

I have sent the BIOS file for you, please check your PM.

Theoretically speaking, your machine should be capable of supporting Wi-Fi 6E or Wi-Fi 7 network cards.

However, you need to download the corresponding WiFi driver from the official website of the Wi-Fi 6E or Wi-Fi 7 network card after installing the respective network card. We do not have the corresponding WiFi drivers available for you to install.

Have a nice day~
