Thank you TSIAlex for this guide. Very helpful.
I have a datapoint to add. This is not a recommendation. It is merely a datapoint.
I have a MacPro5,1 now running boot ROM 130.0.0.0.0 after a successful Mojave Mac OS 14.1 upgrade with a borrowed Sapphire Pulse Radeon RX570 graphics card. The absent EFI support meant that I could not run FSCK and other single user mode tasks. To perform these, I reinstalled the original card, an ATI Radeon HD 5770 and I could perform the single user mode tasks under Mojave. Once these were complete, a reboot command resulted in a normal boot. Booting with the option key held down allowed me to change the boot disk at boot time as usual. Once booted into Mojave with the ATI Radeon HD 5770, I went to System Information and looked for Metal support in case there was any information. It was not listed.
Perhaps I will experience a run time error when encountering an absent Metal API call or have other instabilities. I am not in a position to test for these or other problems. I achieved a normal boot, however, I cannot speak to usability or stability.
My plan is to find a reasonable cost replacement graphics card with EFI support so that I can perform boot time tasks.
Thanks.

[doublepost=1543133465][/doublepost]Thank you so much tsialex for all the help you are taking the time to provide. I have followed these instructions to the tee. Only to be thwarted. No matter what I do. Unplug everything. Remove all cards except for the GTX 680 Mac ver. I can never get pass ROM MP51.0087.B00.
When I run macOSUpdCombo10.13.6 it does not ask to update the firmware. It restarts several times and comes back up fine but no change in the ROM version.
If I just run the Mojave installer it never initiates the shutdown after I enter the admin password for the helper app. It just sits there. If I gto ahead and shut it down and boot with the button down. The lights blink, I let go and the tone sounds. Then a normal reboot back to 10.13.6.
What now?

No, you don't followed the instructions - ComboUpdates don't upgrade MacPro5,1 firmware.
You have to use the MacAppStore full macOS installer for 10.13.6.
First upgrade to MP51.0089.B00, then you use the 10.14.1 full Mac App Store installer to upgrade to 140.0.0.0.0. It's a two step upgrade.
I wish I could have saw this warning before my stupid move.....Don't do this, you will risk loosing your data. Backup your files, upgrade your firmware and then do a clean install.
Did you really bricked your Mac Pro? Nothing on the screen/black screen, no beep? EFI diag led off?I wish I could have saw this warning before my stupid move.....
I did exactly the same thing and it's now blacked out with no starting beep.
Thanks for your help.Did you really bricked your Mac Pro? Nothing on the screen/black screen, no beep? EFI diag led off?
If so:
- you can desolder the SPI flash, reprogram it externally, solder it back (start from this post #929),
- replace the backplane,
- buy a Mac Pro MATT card.
RX-550/570 are not officially supported by the Apple native drivers for AMD GPUs, what you can do is a clean install of 10.14.2 into another drive and check if the ill behaviour disappears, if not, you can start to think into a better supported GPU.Thanks for your help.
It's not bricked, seems like some issue with fusion drive and it's fixed now.
But now it came with a new problem: as I bought a RX550 before doing any research and hoping to get my OS updated, I first plug the rx550(2g) with the mojave, it seems good but some times the screen will black out for like half a second.
I thought it was something wrong with the rx550 which doesn't appear in the support list of mojave so I bought another asus RX570(ASUS Radeon EX-RX-570-O4G), but it's not getting any better.
I tried to monitor the status of RAMs, cpu, VRAMS, but can't find any hints related to that...
I also tried reset smc and PRAM
Read the first post. Do all there until the Mojave part.thanks a lot for the quick respond. Is there any tutorial to follow?. Sorry if this has been already asked.
For some Macs, you have to keep it pressed. Some Mac Pros are really hard to get into Firmware Programming Mode.you can release the button when the light flashes
Read the first post. Do all there until the Mojave part.
This is the easiest way to get into Firmware Programming Mode:
- Shutdown your Mac,
- Press and keep pressed the power button,
- You will hear a loud beep, keep pressed,
- You will hear the startup chime, release the power button when it ends or when starts loading macOS.
I tried too, but the mac just loads the default operating system.
Are you definitely using the full installer, as suggested.I tried too, but the mac just loads the default operating system. When I flashed it to convert it into a 5.1 I didn´t have problems accesing firmware update module holding down the power button. It just went ok. But in this case, I don´t know why the firmware does not load.
The firmware upgrade is only present into the full Mac App Installer for High Sierra, currently 10.13.6.Are you definitely using the full installer, as suggested.
Not the version from mac app store.

i programmed 12 macpro (all original 5.1) in the last 4 weeks
from MP51.007F.B03 >MP51.0084.B00 >MP51.007F.B03 > 138.0.0.0 > 140.0.0.0
all of them had no problem
perhaps the 4.1 > 5.1 flashed models get into the hard mode

The delta upgrade from the Mac App Store don't apply here, since the user has Sierra - no delta upgrades between major releases.
