I'm trying to flash a new BIOS/UEFI firmware on my ASUS UX330UA. It currently has firmware version 300.
Easy Flash 3 (inside the current firmware)
Using EZ Flash 3
(booting to setup), I can browse the folders on my USB key, but cannot see any files. Why can I only see directories, but not files?
Windows
I have already removed and re-installed the latest ATK, and also installed the latest version of Winflash
from the Driver and Tools
tab under Support
.
When I run Winflash
, I get the following error:
How can I flash the most up-to-date BIOS/UEFI firmware?

It appears certain versions of
EZ Flash
will not display any filenames unless their extension is.CAP
or.ROM
.The file that I downloaded was named:
UX330UAK-AS.302
I made two copies of this file, namely:
Both of these copied files with "correct" extensions were then shown in
EZ Flash 3
, and I could successfully update the firmware.Interestingly, it seems this is an unlisted bug - the version of
EZ Flash 3
in the new firmware that I flashed showed all files, regardless of extension.Regarding updating via Windows, I can only assume that
Winflash
needs to be updated to support the UX330, which is newer than the filestamps on the latest version at the time of writing.
