Question Flashing Bios - Continuously blinking (MSI B550 Gaming Plus)

[JamesAtari]

I've tried to flash the bios with a correctly formatted USB.

All seemed okay until the bios LED stayed blinking far past the usual 5-7 minutes, I know I likely need to try a different USB but I'm wondering how I go about cancelling the current attempt?

The LED is still flashing, am I okay to just switch off the PSU and try again with a different USB or could switching off the PSU cause any damage to the board?

As I dont know wat bios is currently installed, do you thin it might be worth trying to flash the original bios (7c56v10) and see if it allows me to work my way up from there?

I’d burn the £30 for a 3100 cpu and try to flash from within the installed bios. Assume bios flashback is a bust.

Assuming no errors in how you have been preparing the memory stick and that it is plugged into the port immediately adjacent to the flash button then it’s possible that the motherboard has a problem.

Once the 3100 cpu is installed you will be able to check to see if the board boots.
If it boots you will be able to check the usb ports and assuming that the ports check out as ok then flash the bios via the installed bios.

You won’t know till you can boot the board.

just reset bios and start the PC see if it starts with factory bios. If not there is something else wrong. YOu only have to remove it for like 10 sec and press the cmos reset button on the mainboard.

I've already tried to post and it didnt work.

I know the board is likely running a pre-5000 series bios, so I can't get into bios at all until its flashed/I buy a compatible chip.

Did you do this?

Updating BIOS with Flash BIOS Button
1. Please download the latest BIOS file that matches your motherboard model from the MSI® website.
2. Rename the BIOS file to MSI.ROM, and save it to the root of the USB storage device.
3. Connect the power supply to CPU_PWR1 and ATX_PWR1. (No need to install CPU and memory.)
4. Plug the USB storage device that contains the MSI.ROM file into the Flash BIOS Port on the rear I/O panel.
5. Press the Flash BIOS Button to flash BIOS, and the LED starts flashing.
6. The LED will be turned off when the process is completed

...

I assume the USB stick has to be formatted FAT32.

Yes I followed the above steps.

I tried several USBs, all formatted correctly and all different sizes/manufacturers.

I have decided to purchase a 3000 series chip and update the bios that way.

Once the 3100 cpu is installed you will be able to check to see if the board boots.
If it boots you will be able to check the usb ports and assuming that the ports check out as ok then flash the bios via the installed bios.

As I dont know what bios the board is currently loaded with, do you think I could just use the 3100 to flash the most recent bios? I've checked to see if any of the bios updates require a specific bios to had been updated previosuly but I cant see any mention of that requirement anywhere on the MSI product page.

So do you think I can go ahead and flash the latest bios? (I will likely be jumping quite a few updates this way).

Possibly, I’d update to the first 5000 series compatible bios first and then try the latest with the 5000 series cpu installed.

This all assumes that the motherboard is good.
