Windows 10: Is it safe to update the BIOS using EZ Flash?

Hi,For the past month, I have been dealing with various Blue Screens and freeze. My laptop ASUS ROG Strix G513RM is doing better now but I can still encounter a random blue screen at times, caused by Kernel Power 41 ID or Hypervisor Error.I tried so many solutions to prevent Blue Screens forever but now I have realized, the only solution I haven't used yet is updating the BIOS through UEFI. The current version is from 2022, according to the UEFI, and the lastest one is from March 2023.Is it safe for me to update the BIOS through UEFI with Flash?Kind regards.

Asus EZ flash 2 doesn't see usb I can't continue the BIOS update


I had the same problem the last week: ASUS H170 BIOS Update from 0903 to 2003, BIOS was burned, reboot, then either (with no storage device connected) "to finish BIOS update you have to select the same BIOS file (.cap file) again" or (with any storage device USB or SATA connected) a black screen.

I researched some hours, tried many things from this and other threads and from ASUS support, then I ordered a new BIOS flash chip (it's not soldered but on a socket - easy removable, one has just to remember the position of the notch on the chip).

For what I found in internet, in my opinion the problem arised because the new big BIOSes need two steps, one burn-step under EZ-Flash and an additional one at or after the first reboot.

As I remember, I removed the USB flash at the first reboot because I assumed BIOS have been burned complete after clicking the final EZ-FLASH "OK" message. But instead of continue booting into Windows 7, I got the black screen.

Every time, I removed all storage devices (USB, SATA) and even the external graphics card, the EZ-FLASH screen came again with the mentioned question for the BIOS .CAP file.
At this point, nothing worked (giving new BIOS, old BIOS, on USB stick, on CD).
Selecting "get BIOS from internet" lead also to a black screen.
Connecting the monitor by D-SUB (old VGA) instead of DVI didn't resolve the problem.

In my opinion, the second burn step after the reboot writes some BIOS I/O routines.
If these are missing, EZ-FLASH is shown but cannot access any storage or network devices.
So, if you put the BIOS on a harddisk, you may avoid never see problem ?!?
I recommend: don't remove USB sticks while burning until your operating system has been started again.

I thought about your solution to buy an USB BIOS burner, then I discovered a company that delivers FLASH chips - they come mainboard-specific with pre-flashed newest BIOS. The costs are 2-3 times the USB burner, but cheaper than RMA the board and no fiddling around with the USB flasher software (as I read in many threads) - just plugged it in, booted, crossed my fingers et voilà: everything works again.

If my assumptions are correct, ASUS should state it either in EZ-FLASH or on the BIOS download page, that the BIOS file has to be present for the whole reboot process, not just for EZ-FLASH burning and ending with an "OK" button.

How To Exit BIOS Mode [Full Guide] (avoid ad links)

One of those should fix it, most likely restoring the proper device to first Boot Priority - either the WIndows hard drive on a legacy install, or Windows Boot Manager on as UEFI install, or a BIOS/UEFI setting for UEFI, CSM or Legacy needs adjusting.

It's also possible it's stuck in BIOS mode because the hard drive is dead or dying, so look for it in BIOS setup under Storage devices to see that it's still functioning. If not you'll need to reseat it, adjust or change the cable, etc. to get it recognized,
or replace the hard drive and reinstall WIndows.

I hope this helps. Feel free to ask back any questions and keep me posted. I will keep working with you until it's resolved.
