New B550 Tomahawk no post

Recently got a new B550 Tomahawk and Ryzen 5600X but am unable to get it to post.  The box shows 3rd Gen Ryzen Desktop Ready but the debug lights keep getting stuck at VGA.  I've tried two different cards with no luck.  I've tried the BIOS flash button (while CPU installed) to update to latest BIOS, it doesn't seem to be doing anything; perhaps already has latest BIOS.  I'm not getting any beep sounds at all, only the debug lights; sometimes it will show CPU & VGA, sometimes it doesn't show any debug lights but no output on display.

 

I'm hoping I don't have to RMA the board as when I did the first boot, my loop wasn't flowing which got me worried and I ended up switching off the power supply.  Did I mess up the BIOS?  Is there anything I can do?

I would try flashing the motherboard with a flashdrive with the new bios installed. Maybe you need to update the bios to use the zen 3 chips. Try a 3000 ryzen if you can, and then try to update the bios.

Unfortunately I am trying to migrate from Intel to AMD, that is my first AMD board and CPU since early 2000's (Athlon XP days) so I don't have a Ryzen 3000 CPU available.  Do I need to have the CPU removed from the board to run the Q-Flash (M-Flash?).  The MSI instructions aren't very descriptive

Tried again with the latest BIOS recently released for the Tomahawk, the red LED by the USB port flashes for a couple seconds along with the USB but then ends up solid red without reading the USB...   Am I SoL?  The BIOS isn't updating.  :(

Try a different USB or external disk? 

 

Might be SoL if you cant drop in a Zen 2 chip in there to do the update. 

 

This is what happens when early adoption + lack of stock combine forces.

Sigh, tried one other different USB and no change unfortunately...  Should I just begin the RMA procedure?

It's a new year's miracle!  Posting from my new rig.  :)

 

Either a miracle or I'm an idiot (most likely the latter), BIOS update successful and am now up and running!  Thanks for the link to BIOS update video
