@Thdub :
Since it is too late for a "Welcome", I want to thank you for your first contribution and for your kind words.
Best wishes from

Thanks but i am on F8 now and this is a complete new Bios with new design and many changes. How Update Microcode, Video OnBoard, and Network? This is not update on new F8 Bios.


Where do you find F8 ? can you send a link ? I can only see F7 on gigabyte website.
You place the files in required folders, update MC database etc.
Check for UBU documentation
[Tool Guide+News] “UEFI BIOS Updater” (UBU)
and ask if you have questions here:

The F8 is the new Final and it looks so great. The new Design so great. I love it.

@Scoty - show a few pics so we can see “new design”

Here some pics. Its all complete new, have more and better Settings. Flash and see self. Hope @Thdub make a new Update with F8.





F8 is now on the offiziel Support Site.

I was really stupid and bricked the board :frowning:
Didn’t know it was even possible with dual bios,
cpu fan isn’t even spinning, tried everything possible as reset cmos, changing psu etc.

Waiting for replacement or hope I’ll be lucky

How I did? few weekds ago I did update and it got stuck at 0% erasing bios. After waiting enough had to switch off the computer, when I switched on it replaced the bios with default bios, that time I could erase and flash well.
second time (with last update I uploaded) it did same thing stuck at 0%, but I did not wait and (I think) I removed the power plug instead of pressing off button (not really sure),
but anyway, studid enough, don’t know what passed by my brain at that moment…
So beware…I’m not sure I will keep on flashing/updating, might do it from within windows with F8 and live without mc update (I don’t use RAID neither onboard graphics)

@scoty , it’s relatively easy to update the bios with UBU, for MC at least: just update database and replace mc with ubu (use same name or short name as dos won’t handle long names)

You have brick with the mod bios?

Problem was at erasing, not writing:
I have no clue what really was the problem here, I just know flash utility couldn’t erase previous bios (also modded) and it was stuck at 0% at erasing part = before writing new bios.
It goes by this order, more or less: copying bios/loading bios, verifying bios, erasing bios, writing bios.

First time this happened (few weeks ago) I waited about 15 mn, starring my screen at 0% erasing, it got me very anxious but had no other way so I restarted, after 2 power cycles it switched to backup bios (I think F6).
Then the utility could erase the bios in place (it didn’t get stuck at 0%), then it wrote modded bios without problem.

And I think what I did wrong that second time it happened is: I didn’t wait much, thinking it would anyway switch to backup bios (like 1st time), and so I turned off the computer the “stupid” way.
That sounds so silly that I’m even not sure I did that (I mean, unplugging the power chord, really not sure…only sure that I didn’t wait like 1st time).

The flash utility verifies the “new bios” before trying to erase old one, so if “new bios” was corrupted or wrong size etc. it wouldn’t even start to erase “previous” one.
It might be those modded bios are causing problem at erasing…If you switch from official (or default) to modded one it should work (=erase) without problem.
But a future flash from “modded” to “updated mod” might be problematic (erasing), and it might be safer to load default one before updating anyway.

I really have no more clue that that, I’m not specialist in gigabyte bios neither in flashing process.

BIOS Contents, good, bad, mod, or stock wouldn’t matter to the erase process, so I doubt it was due to mod BIOS made it fail to start or continue with the erase procedure

Bios content is surely ok otherwise I think it wouldn’t even start the erase procedure,
but what you think it could it be that it happened twice (being stuck at 0% erasing) ?

The erase procedure could be programmed into some other chip, or yes, it may be only some modules of the BIOS are messed up.
Anything could cause that, random glitch, unstable system, memory error etc.

But the z390 Designare have Dual Bios. Normal whene first Bios dont start you can switch to second Bios. Why have you not boot the second Bios? I have make a Mod Bios now with Updates but i wait for flashing now. Why can not flash with Bios internal flashing update tool?

Link down :’(

Anyone have any links or backups? Would really appreciate.
