I have been trying for a while to find a motherboard that supports a Ryzen 5700G or at least can be BIOS upgraded without a CPU.
Been through 3 MSI Motherboards so far with no luck (including 1 DOA and 1 that doesn't want to update BIOS).

All I need is a dirt cheap Motherboard that has:
- Support for BIOS Flash without CPU.
- Support for 5700G and Graphic output (HDMI).
- 6 SATA3 ports (without losing any of them to m.2 slots)
- 1 m.2.
- 4 RAM Slots
 
MSI x470 Gaming Plus Max - No way to update BIOS
MSI B550 Tomahawk - BIOS didn't update via flash button
MSI B550 Gaming plus - DOA

Let's just say I don't want MSI.

Was thinking about ASUS or AsRock. Gigabyte has XMP issues and I will need that.
 
You've done something wrong then especially with the MSI B550 Tomahawk, I flashed at least half a dozen of them with BIOS flashback. I assume you've sent it back or don't have it any more, as I can tell you exactly how to get it to flash.

Also I assume you did it with a totally unpopulated board e.g. no CPU/RAM installed?
 
Tried it with:
2 different sticks (Sandisk and Kingston)
2 different BIOS versions
NTFS/FAT32
RAM installed
RAM uninstalled
CPU installed
CPU uninstalled
RAM & CPU in/out
 
Well if you live anywhere near me, I am happy to flash it for you if you want to bring it over. Helped many people in the past. :)
 
Pretty sure it's only MSI that do b550's that the M2_2 doesn't share lanes with the sata ports, bios flash can be fussy about the stick used, usually there's a colour coded usb port that needs to be used for flash back.

Amd do an update kit where they loan you a cpu.

That is definitely something I will look into. Thank you!

MSI Mobo's are dirt cheap, that's why I even bothered with it.
To quote someone from MSI's forums "It would be really nice if MSI made a full tutorial and a list of requirements for Flashing BIOS without a CPU."

You mean this?


The B450 mortar or tomahawk max is probably the cheapest ones with flashback.
 
1 Download the bios and rename it to MSI.ROM
2 drop the bios onto a USB drive that has been converted to FAT32
3 make sure the atleast the CPU power lead and motherboard 24 pin power leads are connected as a minimum and the psu is plugged in although you can still do this will a fully built system but you need to make sure the PC is turned off but power is connected.
4 insert the USB into the correct slot for flashing, this will usually be marked on the back of the rear IO and will specify in the manual.
5 press the flash button then go make a cup of tea or something and wait till the light stops flashing then remove the USB and you should be good to go.

Yeah, didn't work... after a quick google search, i stumbled across reddit and MSI forums, every one of them had issues once all the steps were followed.
No Post
CPU Still not compatible
No Flash
Someone tried with 4-5 different sticks and only worked with 1.

It's irrelevant now, I still have the x470 and i delayed the collection for a week. Maybe I will receive the 200GE from AMD and try a normal flash and see if that does the trick.

If not, i'm still looking for a ASUS, ASROCK b550 with 6 SATA Sockets and 1 m.2 that doesn't share bandwidth with the sata slots.
50-100 quid.
 
I've flashed my X570 tomahawk and a B450 mortar from USB with no problems. I did specifically choose a USB 2.0 8GB (I think) as I'd heard that usb 3.0 sticks and some larger capacities had caused problems for other people.
 
So, finally received my new motherboard and tested everything. Did pay quite a lot for it but it would have saved me a lot of time to just buy it in the beginning.
Went for ASUS ROG STRIX B550-F GAMING, got it for 150, so i'm not complaining and it had 1401 BIOS already flashed.

As for the other 3:
MSI x470 Gaming Plus Max - No way to update BIOS - gonna return, shame they didn't implement BIOS flashback button.
MSI B550 Tomahawk - BIOS didn't update via flash button - Confirmed DOA by the store.
MSI B550 Gaming plus - DOA - Confirmed DOA by the store.
That should tell me a bit about MSI... definitely not gonna use them again.

So now, after all this wasted time, my backup system is almost completed, just need to move over the storage and boot drive from the other system.

Thank you all for your help. I wish MSI would make better boards...
 
Glad you got it sorted. :)

MSI boards are fine, used countless numbers of them you've obviously just been mega unlucky.
