yes i know, but it doesn't go with vega 64. Same, not work.
First, don't try to upgrade firmware with USB installs, do from macOS. I never tested with VEGA GPUs, but I bet that you are doing something wrong or something is wrong with your EFI partition/macOS install or your are doing from createinstallmedia USB.

efiflasher works with every METAL card that I tested and various people here have VEGA GPUs and no one reported problems with the upgrade. efiflasher works even with NVIDIA GPUs that are not supported, lots of people have being upgrade firmware with NVIDIA 9xx and 10xx cards and 10.13.6.

I'm trying to reinstall the system?
 
I reinstalled Mojave, no change. continue to update the firmware.
You have to find what is wrong with your config or what you are doing it wrong.

Do a basic 10.13.6 install into an empty disk (use a SATA disk, use APFS, simplest install possible), remove all other disks, then use the 10.14.4 full installer to bootstrap the firmware update.
 
Since MP51.0089.B00 to 138.0.0.0.0 upgrade, efiflasher don't have a progress bar anymore.

thanks for this info, I think this clarifies for me why I did not saw a EFI flash progress bar screen when upgrading to 141.0.0.0 ?
(running GTX680 EFI flashed)

Yes, since the METAL requirement efiflasher don't have a progress screen. No upgrade after MP51.0089.B00 have a progress bar, just a white screen.

Most of the METAL GPUs for Mojave are GOP GPUs and don't have pre-boot environment with a MP5,1 and show nothing before the drivers are loaded, so Apple removed the progress bar.

thanks, I still find it strange why Apple has removed the EFI flash progress bar.. ?
I dont understand why they remove this handy progress bar..

It's the only way to do the firmware upgrade with GOP GPUs. GOP GPUs only show the screen after the drivers are loaded, so Apple removed the progress bar to be possible to do firmware upgrades with non-Mac EFI GPUs.

unfortunately, the firmware is not updated at 10.13.6
 
Download the FULL INSTALLER for macOS Mojave 10.14.4 and a window like this will appear:

Click shut down. Enter your password. Wait for shut down. Wait 1 minute. Press AND HOLD power button on front of tower. Wait for chime AND WAIT ANOTHER 15 SECONDS before releasing from power button hold. CD/DVD drive will open. Computer will cycle and then restart.

The ONLY difference with Mojave is the full installer is harder to obtain. That's it. It's the same process that's been used for many previous OS releases with firmware updates.

I did the same in the same way, but unfortunately it does not update. I'm not first upgrading the firmware......
 
Yes. But can be turned off in the monitor menu
Resolution is still a problem. Like I said, use a DVI connection and a monitor with a standard resolution equal or less than full-HD. This is a know and old bug with efiflasher.

Anyway, please open a thread about your problem. This is going for more than a page and it's de-railing the thread.

But the previous update also had this monitor. What can I do?
