ASUS bios flash not working

[Infinity425]

I recently purchased a Ryzen 3600,  ASUS Crosshair 6 hero motherboard, and some trident z ram from a micro center. To replace my old 4690k. I assembled the part to the best of my knowledge and when I turn it on all the leds turned on and fans started to spin but it did not post and I was getting Q code 8. My first thought was that the bios hasn’t been updated for ryzen 3000. So I got a flash drive did an MB’s partition and set the file system to fat32 as other guides told me to I plugged in the drive and pressed the button for three seconds and the light flashed for a little bit and then went solid and did not turn off as the manual said it should once the update was completed. I’ve tried every solution I could find online. Thanks in advance.
