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 your USB flash drive.
3. Connect the power supply to CPU_PWR1 and ATX_PWR1. (No need to install CPU and memory.)
4. Plug the USB flash drive 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 have flashed b500m mortar wifi for my friend before and it went perfectly, and the light should keep blinking for bout 5-10mins, but in my case the led light was constantly on(not blinking) and also the cpu debug led didn't turn on, so i am confused what is happening.
i followed this procedure "

Probably the best how-to video on using MSI BIOS flashback. He's got several tips for little details that can make a flash unsuccessful if you get it wrong. He's on a different MSI board but it should work the same for yours.
