Asus H 170 Pro is the Motherboard and I thought that is a good idea to update the bios (after that I've realised that was not)

I've copied the Bios update file (H170-PRO-ASUS-1803.cap) to a 4GB flash FAT32 and hit update. After the progress bar rich the end, I restarted following the bios update dialog.
At this point, all I have it's a black screen with the USB flash plugged in or If I remove the flash, I can access the UEFI but there is a single option: " to finnish BIOS update you have to select the same BIOS file (.cap file) again to continue updating the BIOS. "; sounds good enough but If I hit OK and choose via Storage devices option EZ doesn't see the flash.

I've read about the size of the flash and I've shrinked in cmd to 400MB formated again to FAT32 and after that I've copied the .cap file.

Unfortunately, the same result, the flash is not available using any of the USB mobo's ports.
Anyway, there is no SSD/HDD/optical drive plugged in.

Not so sure about the indicated File Path: fs0:\ where it is more exactly and if matter.
The stick should be bootable?
Any advice? I appreciate it!

For sure you are right, and I'll update the thread for those who still believe that this "EZ?!" could be as easy as it looks; don't EVER fix what isn't broken :D still searching for a solution to continue the update. I appreciate it!

LE:
Ok, here we go again. I've tried to use bupdater in DOS with FAT/ FAT32 formatted sticks using Rufus according to this (MBR partition UEFI/DOS, also creating bootable disk with FreeDOS), new downloaded BIOS files in different versions; After the file is checked, the next step is Loading file or something. Instead of that I receive "unknown result!".

The archives are not corrupted, I've tested the zip files and as I've said I've tried different BIOS version files.
Any thoughts ?

After that I'll apply the final solution removing the battery but I'm a little bit scared about using this.
Thanks,
