Do NOT use it on a MSI AMD boards from 3xx boards Series. [like X370/B350]
(its OK to use for X399 AMD models as 3xx exception)
It's OK to use for any other newer than [X370/B350] MSI AMD boards or Intel boards.
V1.13 Add extra support for ME FW Update for all MSI Z490 Series:
MPG Z490 CARBON EK X
MEG Z490 UNIFY
MEG Z490I UNIFY

How to use:
Prepare an USB key and format it in FAT32
Download the tool from the link:
Forum UEFI Shell Flash tool [V1.19]
or use special version for Blind Flashing:
(It's useful when need to flash BIOS without display [but the PC can still boot and works fine] and performs auto flashing)
For Blind Flashing only: Forum UEFI Shell Flash tool [V1.19]
Short instructions for for Blind Flashing:
[prepare the USB key for flashing,[see details below how to prepare it] then shutdown the PC,
and disconnect temporary any other storages except that USB key that will be used for flashing]
Then turn on PC and wait auto flashing to start and finish automatically.
[when blind flashing is complete the PC will auto shutdown,
then you can remove the USB key and reconnect the rest of your storages and turn it on]
General instructions for USB key preparation within Windows for both versions:
and extract all contents over the USB key, [FAT32 formatted]
copy/extract the folder structure As Is to the USB key.
Do not omit the folders and sub-folders.
I.e: USB key root structure should looks:
then also add/copy/extract desire MSI UEFI BIOS that you want flash,
on USB key main/root (\) folder.
for example I want to flash a E7A34AMS.M90 BIOS,
and copied the BIOS file on USB key main/root folder/directory:
Next reboot computer,
and ensure in BIOS Setup:
UEFI Boot is allowed,
and Secure Boot disabled.
Then boot from USB key,
in UEFI Mode,
You can press F11 during BIOS post/logo screen, then when BBS popup after a while,
choose the prepared USB key with UEFI in front as name.
i.e: choose to boot from:
UEFI USB your drive
then wait, and you will see the BIOS version shown that is going to be flashed.
and you can press a key to proceed with flashing.
If you don't want to proceed with flashing,
you can press "q" to abort at that point.
when flashing starts,
wait patiently to finish,
ensure successfully message on the screen then reboot or power off the computer.
Note1: Be sure to place only one BIOS file on the USB key at the time, before proceed with flashing.
Note2: Due BIOS flashing nature, (which consider every flashing as potential dangerous)
Flash and use at own risk as usual.
Note3: You can use it to downgrade the BIOS too.
