Problem with MSI X570 Tomahawk WiFi flashback feature.
Problem with MSI X570 Tomahawk WiFi flashback feature.
He has built a PC with a R9 5900X and an MSI X570 Tomahawk WiFi, but the motherboard doesn’t support the CPU by default. He installed the BIOS on a USB drive formatted as FAT32 and labeled it "MSI.ROM." When he tried to flash it, the LED near the button flashed three times before stopping, and the USB drive also stopped working. He’s used two USB drives but hasn’t succeeded. The purpose of BIOS flashback is for such repairs, yet it doesn’t seem to help here. What could be the reason?
I'm just confirming the details you mentioned. Did he connect the USB to the right port? You can't use any rear port randomly—it needs the specific one for BIOS flashback. From the images, it looks like it's on the top leftmost position while facing the board straight up, as if installed inside a case rather than just placed on top of a box before casing. ASUS clearly labeled this area with a red square indicating the correct port.
I don’t see any other explanations for this, do you? It’s just why I keep letting the store flash the BIOS for me. If something goes wrong and they brick the board, they’ll have to take responsibility, right? I’ve already ordered all the parts online for my next build, but unfortunately I’m stuck because a Mobo and CPU are still missing. Since most X570 units come out of box with a 5000 CPU, there’s no other option—waiting is the only choice so I can avoid this headache.
I recommended he bring it to a nearby store or check Scan.co.uk for assistance. I've seen many discussions online where people face problems with the BIOS flashback not working, then suddenly fixing it after hours of effort. It’s hard to pinpoint exactly what’s causing the issue from all these posts. I suggest trying to format the USB stick using Rufus, though he only has a Chromebook. He also sold his old PC, and unfortunately isn’t local—I could visit if needed. His skills with hardware are declining.
You didn't mean that. It seems you were testing with memory in and out, CPU in and out, without mentioning the GPU or removing all hardware from the board. Please revise your original post for better clarity so I can help you without confusion.
I'm sorry for the oversight. I assumed everything was included. For next time, I'll state it clearly: no cpu, no ram, no gpu, no usb, no sata, no m.2, no hd audio cable, no front panel. Should I proceed? He resolved it by using an additional usb stick, and it functioned properly.
I can't move or guess without proper info. This won't assist with troubleshooting. Thanks for the blunt feedback—I'll avoid trying to help further.
