Cant flash a bios to a b450 motherboard.

Hi,

 

Ive just bought an MSI b450 gaming pro carbon ac and im trying to flash a bios onto it so it supports my r5 3600, however, i am having a lot of issues trying to use MSI's bios flashback feature. I have tried 6 usbs with so far with no luck. All the usbs so far have made the motherboard give the same reaction of 2 flashes then a constant red light on the bios flash LED. 

I have also tried using different power supplies.

When i try to boot the pc for the first time all that happens is the fans spin and then a cpu error led shows on the motherboard so its clear that the bios has not been flashed to it successfully. I dont have an older ryzen chip to put into the motherboard to use M-Flash so what else can i try?
 

Thanks for responses,

Most motherboard are capable of fashing the file with a .exe file

Main PC [The Rig of Theseus]:

CPU: i5-8600K @ 5.0 GHz | GPU: GTX 1660 | RAM: 16 GB DDR4 3000 MHz | Case: Lian Li PC-O11 Dynamic | PSU: Corsair RM 650i | SSD: Corsair MP510 480 GB |  HDD: 2x 6 TB WD Red| Motherboard: Gigabyte Z390 Aorus Pro | OS: Windows 11 Pro for Workstations

 

Secondary PC [Why did I bother]:

CPU: AMD Athlon 3000G | GPU: Vega 3 iGPU | RAM: 8 GB DDR4 3000 MHz | Case: Corsair 88R | PSU: Corsair VS 650 | SSD: WD Green M.2 SATA 120 GB | Motherboard: MSI A320M-A PRO MAX | OS: Windows 11 Pro for Workstations

PSA: No, I didn't waste all that money on computers, (except the main one) my server cost $40, the intel NUC was my old PC (although then it had 8GB of ram, I gave the bigger stick of ram to a person who really needed it), my laptop is used and the second PC is really cheap.

I like tinkering with computers and have a personal hatred towards phones and everything they represent (I daily drive an iPhone 7, or a 6, depends on which one works that day)

Before pressing the bios flash button make sure you have done the following

1. format your usb drive as FAT32, not FTFS!

2. Download latest BIOS and rename it MSI.ROM

3.  Following instructions Page45 on your manual.

I have tried. All the usbs i have tried are formatted as FAT32 and the bios file is renamed correctly nothing has been working. The flash led flashes 3 times and then its just solid red...

Maybe try flashing to 7B85v17 first as this was the BIOS to first add support for ryzen 3000 series. Also make sure only your USB flash drive is connected no other usb devices are connected (kb/mouse including internal USB devices like AIO/fan controllers)

 

If not you'll need ryzen 1000/2000 series cpu to flash bios. Maybe find local computer store and see if they will flash bios for you? Or return board for MAX version with supports 3000 series out of the box.
