Review of past BIOS updates for ASUS motherboards
Review of past BIOS updates for ASUS motherboards
There are several factors to consider here. I noticed @Hinjima pointed out the missing 8-pin EPS connection, which is essential. The flash drive might be plugged into the incorrect USB port or using a different partition table than the MBR. Your specific board tends to disregard GPT drives during flashback. Have you executed the renamer? Are file extensions enabled to confirm it isn’t a corrupted file (like xxxx.cap.cap)? It could be the wrong BIOS version—WiFi or board revision differences often stem from larger issues. The system might simply reject USB drives. Older, compact USB2 drives are advisable. Likely there are other overlooked details, but the fact that this is your second board suggests the process itself may be flawed rather than the hardware. Alternatively, you could boot directly into BIOS and flash from there. Asus boards generally accept most devices at that stage. You probably don’t need a USB stick at all—just explore your SSD and locate the BIOS file to proceed.
I’ll note that all my BIOS Flashback USBs are also USB 2.0, which I’ve used with ASUS motherboards. I’m using an older model from 2007.
Same with ASUS as well. Given your CPU is compatible, I think flashing probably won’t help much. How long did it take before the system powered on after a CMOS reset on DDR5 devices? First boot can sometimes take 5 to 10 minutes, especially if nothing appears until it suddenly comes to life.
Don't put the BIOS file into a folder; copy and paste is directly into the FAT32 formatted USB drive. I've had mixed success when the .CAP file is in a folder, but no issues if directly copy-paste into the USB drive. Across multiple ASUS and Gigabyte motherboards.
