I hope this forum isn't dead. lol

I need to downgrade my original 4,1 (that was upgraded to 5,1 via FW update tool) reason being need to warranty it out the system for an unrelated problem.

The only thing is it keeps failing to downgrade

Current FW is MP51.0087.B00 that was supplied with High Sierra FW update

I downloaded the patched version of the FW tool http://forum.netkas.org/index.php/topic,852.msg31640.html#msg31640

I still kept getting a 5570 error.

I think I have an idea whats going on, I Believe I have to downgrade to MP51.007F.B03 and then to MP41.0081.B07?

or can it go MP51.0087.B00 right to MP41.0081.B07?



Okay so under OSX High Sierra, i downloaded both FW packaged from Apple 1.4 & 1.5 with the DMG mounted to the desktop the patched FW utility was able to create a ramdisk and said to shut down.

I did the whole flash procedure (hold power button till light flashes & deep beep) however something isn't right, the apple logo appears and the flash progress bar appears but it goes from 0% instantly 100% (I'm talking blink and you'll miss it) and nothing happens afterward. If I shut down and reboot, firmware is still MP51.0087.B00

Remember I'm trying to DOWNGRADE, yes, I'm using all the original OEM hardware CPU/GPU.

I don't know whats keeping it from flashing or at this point its even possible anymore.

I saved the contents of the ramdisk before I shut it down to attempt the flash

Perhaps someone could help shine some light on this.

Have you tried using official Apple Firmware Restoration CD?

Hey guys,
I'm having problem to rollback the firmware of my Mac Pro 5.1 2010, from MP51.0089.B00 EFI to MP51.007F.B03. Is there a way to make it possible, and, if i choose the downgrade to 4.1 with the help of the firmware upgrade utility, it will not brick my Mac?
Thanks

I could not get the firmware updater tool to work. Error 5570 then Error 5530.

So I hacked the scripts within the tool and ran them directly. I now have a MacPro 2009 which reports Model Identifier: MacPro5,1

Root problem: you need to have BOTH the 2010 and 2009 EFI upgrader disk images available so this tool can prepare both the upgrade and downgrade paths. And the tool no longer seems to be capable of downloading them (or at least not for me and anyone else getting the 5530 error). Digging into the compiled .scpt file inside the tool, it's pretty clear what is wrong. But the script is run-only compiled and I can't fix it directly.

So I manually downloaded them and then had to hack the subsidiary shell scripts embedded in the Firmware Tool app and run them directly by hand.

Here's what I did:

0/ Reboot in recovery mode and disable SIP (Recovery mode, Terminal,  csrutil disable ). Reboot again.

1/ Download *both* EFI updater packages from Apple
https://support.apple.com/kb/DL989?locale=en_US
https://support.apple.com/kb/DL1321?locale=en_US

2/ Use DiskUtility to convert each disk image to a new read/write image

3/ Mount the first image for the 2009 firmware. Rename the mounted disk to Mac Pro EFI Update 2009

4/ Mount the second image for the 2010 firmware. Rename the mounted disk to Mac Pro EFI Update 2010

5/ Run the netkas forum Mac Pro 2009-2010 Firmware Tool.app
(it will fail, but it will create the RamDisk)

6/ Hack the ExtractAndPatchEFIFiles.sh script buried in my ~/Downloads/Mac Pro 2009-2010 Firmware Tool.app/Contents/Resources/ directory with this new version:
Code:
#!/bin/sh

pushd /Volumes/RamDisk

# we mounted the EFI update disk image manually
# hdiutil attach -nobrowse EFI2010.dmg
pkgutil --expand '/Volumes/Mac Pro EFI Update 2010/MacProEFIUpdate.pkg' Expanded
cp Expanded/MacProEFIUpdate.pkg/Payload Payload
tar -xf Payload
mkdir MacProEFI2010-2009
mkdir MacProEFI2009-2010
cp 'System/Library/CoreServices/Firmware Updates/MacProEFIUpdate15/EFIUpdaterApp2.efi' MacProEFI2010-2009
cp 'System/Library/CoreServices/Firmware Updates/MacProEFIUpdate15/MP51_007F_03B_LOCKED.fd' MacProEFI2009-2010/MP41_0081_07B_LOCKED.fd
rm -R Applications
rm -R Expanded
rm -R System
rm Payload
hdiutil detach '/Volumes/Mac Pro EFI Update/'

# we mounted the EFI update disk image manually
# hdiutil attach -nobrowse EFI2009.dmg
pkgutil --expand '/Volumes/Mac Pro EFI Update 2009/MacProEFIUpdate.pkg' Expanded
cp Expanded/MacProEFIUpdate.pkg/Payload Payload
tar -xf Payload
cp 'Applications/Utilities/Mac Pro EFI Firmware Update.app/Contents/Resources/EfiUpdaterApp2.efi' MacProEFI2009-2010
cp 'Applications/Utilities/Mac Pro EFI Firmware Update.app/Contents/Resources/MP41_0081_07B_LOCKED.fd' MacProEFI2010-2009/MP51_007F_03B_LOCKED.fd
rm -R Applications
rm -R Expanded
rm -R System
rm Payload
hdiutil detach '/Volumes/Mac Pro EFI Update/'

popd

patch /Volumes/RamDisk/MacProEFI2009-2010/EfiUpdaterApp2.efi EfiUpdater2009.patch
patch /Volumes/RamDisk/MacProEFI2010-2009/EfiUpdaterApp2.efi EfiUpdater2010.patch

7/ Then run the script directly. Using terminal:

Code:
cd ~/Downloads/Mac\ Pro\ 2009-2010\ Firmware\ Tool.app/Contents/Resources/
./ExtractAndPatchEFIFile.sh
sudo UpgradeEFI2009-2010.sh

8/ Shutdown then power on and hold down the power button. Don't let it go. You'll hear the beep indicating EFI update, then it will reboot again. Keep the button down. In my case, the CD drive popped out. I waited a while, then pushed the CD drive back in. Eventually, I got bored and let the power button go. A little while later it rebooted again. Maybe even one more time.

9/ Login, check all is well with System Info.

10/ Reboot into Recovery mode again, enable SIP (Terminal, csrutil enable). Reboot


I'm pretty sure I captured all of that correctly. Hope this helps others.

(If anyone knows how to contact the original author of the update tool or can get the source, I'd happily fix it)


I was getting 5570 error code but finally was able to upgrade by upgrading 4,1 firmware to latest version and by then using above procedure.  System now reboots to white screen for Mavericks drive or to Apple and progress bar which does not move for High Sierra SSD.

Help!

Never mind.  Turned out to be a bad 16GB RAM module or slot.

All is good!
