Great, good to know. My question is, can I take out the USB Drive that is plugged in right now that I tried these steps on? The solid green light is on, and I'm wondering if I can just pull it out without causing any damage to the motherboard. Pretty sure a solid light means the procedure didn't start. The light should be OFF when it's done. You can shutdown the system. It's fine. The BIOS flashback didn't work or should I say didn't start. Answer from Nemesia on forums.tomshardware.com

r/ASUS on Reddit: Flashback solid green light
December 9, 2020 -

Help me im about to smash this fucking motherboard to pieces its an ASUS x570 ROG STRIX F GAMING. Ive been trying for about 7 hours to flash my bios something ASUS claims take 5 mins using their flashback button. Well every single avenue ive tried I get 3 green flashes followed by a solid green light. Ive formatted my usb stick and set to FAT32. Ive tried windows and Bootice so far to no avail. Ive tried multiple USB sticks and it appears whatever has gone on my first USB stick I tried has been killed. Ive cleared the CMOS and tried again. Ive triple checked im downloading the right bios thats compatible with my motherboard after seeing someone else have this trouble. Ive tried with just the motherboard connected to the PSU, ive tried it as a full system with the new 5600x with the RAM and everything plugged in asif it was a working PC. Im at a complete loss, wait months for my new stuff to arrive for this shit to happen. Please please please can anyone offer any advice

January 7, 2025 - This stops the infinite loop as the LED stops blinking and becomes solid green, indicating that Flashback failed (obviously, there is no USB Drive inserted) and the power button is re-enabled.

r/ASUS on Reddit: Bios Bios flashback light stuck on green
January 13, 2023 -

Just started my first build, I was aware I may had to do a bios update and I do because my bios is not up to date for my 5600 cpu. So I got a 32gb usb and formatted it to FAT 32. Went to the asus website and downloaded the latest bios for mobo. Did the renamer and put the CAP file in my root folder. Light turned solid green, searched reddit and found the convert to mbr and did that, then used disk management to "add volume" which aloud me to put it into FAT 32 and put files on the drive after converting to MBR. I am still getting a green light and have no clue what to do from here. Can anybody help me out or point me in the right direction?

November 26, 2022 - What I can tell you is that in general use, the green LED is lit and not blinking. So if you tried to use bios flashback and it didnt blink, then it didnt even try to flash.

[SOLVED] - Can't perform BIOS Flashback ? | Tom's Hardware Forum
April 29, 2021 - So as I've read online this isn't too uncommon and a BIOS Flashback is a possible solution to my problem. I believe I have formatted the USB drive exactly as instructed with only the .cap file on it, when I hold down the Flashback button, the green LED does not continue flashing for longer than about 3 seconds. It goes back to solid colour.
