BIOS Update stuck on B550M PRO-VDH WIFI motherboard
I'm pretty new to building computers so I might have just done something wrong and I'm not sure what. I was flashing a BIOS update with a USB and the light that blinks indicating it has just been blinking for the better part of 2 hours now. I couldn't actually get it into the BIOS on a monitor for some reason, and my brother who was helping me said it probably needed a BIOS update since I'm using a Ryzen 7 5800XT and the motherboard is only 3rd gen ready. If it helps, the RGB on everything is on and the fans are spinning. The CPU light on the LEDs that are for the POST test is on as well.
Specs:
Ryzen 7 5800XT
AMD Radeon RX 6600
32 GB DDR4 3200MHz
B550M PRO-VDH WIFI motherboard
Some random 240GB SATA SSD that works
750W power supply (MAG A750GL)
The reason I'm asking here is because I heard that stopping a BIOS update is kind of dangerous and I don't want to brick this motherboard. I want to know what I should do because I'm using this old 2GB Lexar flash drive from probably 2010 to flash the BIOS onto the motherboard. I have a feeling it doesn't like that drive, and I was gonna try with a 64 GB flash drive I got from Microcenter, but I have some other old flash drives that might work too.
UPDATE: I just turned off the power supply and went with it. I have a 32GB partition on the 64GB drive, and I put the proper most recent version of the BIOS on there (Version: 7C95v2O). Renamed it "MSI.ROM." When I plugged it in, the LED on the USB stick flashed for maybe 1 second. The LED on the USB stick seems to appear whenever you read and write something, so it must have read it for like a second before falling into some sort of infinite loop. I assume it didn't like how I have my drive, but I really don't have anything better. What are some other options? I'm pretty lost so anything is appreciated.
