Detailed description:
Hello Everyone my name is Marco, i've been struggling for months now with the infamous Bios update that causes the issue in the iitle. I noticed there was a fairly long discussion going on that was closed last january, seems like the issue was fixed by downgrading to an older version of the firmware that was sent via PM by one of the mods (@Blake_ASUS ). As I'm new to these forums i'm not sure whether it is appropriate to contact the mod directly, so i apologize in advance.
Here is the above mentioned topic.
Please help!

Hi @Cookino ,
I would like to know the BIOS you updated to which version?
Also, I send a PM to request your SN.
Please check.
Thank you.

Hello, thanks for the quick reply, i sent my SN via PM. Could i ask how i can check the BIOS version?
The SN shown on MyAsus app is clearly wrong as it is jus a progression of numbers from 0 to 10 over and over.
Looking forward to your feedback,
Thanks again for the support.
