Firmware Tool for 4,1 to 5,1 upgrade
- Thread starter bxs
- Start date
- Sort by reaction score
The method you quoted - the one outlined by Diepstor in post #141 - worked fine for me.
But... there are a few small caveats which need to be addressed.
1) Diepstor (or verveguy, it isn't clear which) made a small mistake in unmounting the volumes:
The first hdiutil detach '/Volumes/Mac Pro EFI Update/' should be hdiutil detach '/Volumes/Mac Pro EFI Update 2010/'
and the second should be hdiutil detach '/Volumes/Mac Pro EFI Update 2009/'
This caused the issue
hdiutil: detach failed - No such file or directory
hdiutil: detach failed - No such file or directory
But it isn't harmful to the process, just untidy.
Secondly, when specifying the final command, it should be sudo ./UpgradeEFI2009-2010.sh - note the ./ in front of the shell script name.
This caused Alex Rets' failure to launch in #167.
If you make those two changes to the instructions, it all works.
hi. thanks for the info. i would test it on monday and will give an update...
To the instructions:
0 - i installed mac os x 10.6. (so there is no SIP to disable)
1 - downloaded the two firmware updates and transferred them to the desktop.
2 - converted the two dmgs as read/write (as instructed).
3 - mounted image and renamed to ... 2009. (firmware 1.4)
4 - mounted image and renamed to ... 2010 (firmware 1.5)
5 - ran the Mac Pro 2009-2010 Firmware Tool (i got he 5530 error) (tool is on the desktop).
6 - edited ExtractAndPPatchEFIFiles.sh (see below) (right clicking on the Mac Pro 2009-2010 Firmware Tool > Show Package Contents > Contents > ExtractAndPPatchEFIFiles.sh)

Error while writing firmware updater for EFI
the message: "Error while writing firmware updater for EFI" is what concerned me. so somewhere in between, there is a mistake...
i do not know if it is relevant but, 2 folders were created in the RamDisk (MacProEFI2009-2010 & MacProEFI2010-2009).
sorry for the long post. i hope i get some assistance. thanks.
Hello, how are you? I did the process yesterday without any problems, I'll tell you the steps I take from MacOS 10.11.6 .
Update the firmware at your own risk.
1-Download Update firmware to 1.4 from here https://support.apple.com/kb/DL989?viewlocale=en_US&locale=en_US
You install it directly. Then you follow the firmware update steps , shutdown , hold power button etc.
2-You verify in about this Mac / System Report / Boot ROM Vesion = MP41.0081.B07
3-csrutil disable from recovery mode , and reboot
4-download tool v1.2 https://github.com/pigsyn/MacProFirmwareToolUpdate/releases
5-download firmware 1.5 https://support.apple.com/kb/DL1321?viewlocale=en_US&locale=en_US and mount ( Not to install )
6- run firmware tool update. select update to 2010 firmware. and then you follow the firmware update steps , shutdown , hold power button etc.
7- After the reboot, check the boot ROM version = MP51.007FB03 And if you look at the model indentifier now it's MacPro5.1
I hope it helps you.

Hi all,
I have taken delivery of a Mac Pro 4,1 and from what I can tell it is mostly stock. GT 120 GPU, 16GB RAM and Quad Core Xeon 2.66.
I have tried & tried the firmware update to 5,1 using the firmware tool. I do not get any errors, The tool gets to the point where it asks to shutdown. I shut down and hold power button in until it flashes rapidly then the tone chimes, then the Mac startup tone starts.. the system boots. DVD Drive does not eject.
Ive done this 3 million times and am at a loss.
OS is El Capitan - Boot ROM Version: MP41.0081.B07.
Any advice greatly appreciated as I want to start getting on with the upgrades etc!
Thanks
I have reseated GPU, SSD in slot 1, GFX Card and Nothing plugged into USB. Even tried the procedure with no GFX Card plugged in.
At a loss
.
PS< I have checked csrutil in El Capitan and its status is disabled.

I'm having the same issue! Did this successfully years ago and I'm dumbfounded why it's being so difficult this time around. Everything stock, dual CPU and dual GT 120. Only oddity I noticed is "About This Mac" doesn't show the year.
Can I pull the EFI chip and flash it with my chip programmer? LOL

Hello, I have exactly same problem - MP 4.1 dual processor, El Capitan. csrutil is disabled but nothing happends after long beep. Just boots to El Capitan, with no progress bar. Please help.
Hi there. I’ve been unable to flash 4.1 to 5.1 Mac Pro for the last couple of days. Tools seem broken.
I feel I’ve tried everything. From doing what I’ve successfully done in the past on another machine, to re-read and follow all the normal online tutorials again, tried different operation systems, from Mountain Lion, to Yosemite, El Capitan and High Sierra. Did SMC, PRAM and NVRAM resets (x3 and x5 times). Disabling SIP afterwards, of course, and before attempting to flash. Changed the time/year of the clock as some suggested. Even tried reflashing a blank original 4.1 firmware into the board, via Romtool, and then trying to do all the normal ways again (after inserting the serial number). Did try to flash with the tool manually with the instructions suggested a couple of posts above. Nothing seems works.
I feel the software flash 2009-2010 (originally by netkas) is somehow broken again, as the version from 2017 and the newer version patched with fixed URLs from 2022 (https://github.com/pigsyn/MacProFirmwareToolUpdate), seem to not be working for me and other people. I never get to see the fat loading bar. It goes straight off to normal desktop environment. Funnily enough, if I try to change the clock to an earlier year, it always gives me the 5530 error. Only when I put the clock back to current 2024, the Ramdisk seems to get all the needed files and it all seems to going to work, until I shutdown/restart the Mac holding the power button, releasing upon flashing lights or beep sound, and then back to the desktop environment
If anyone could shed some light into this, would be great. I've got the b07 firmware, which is the one on firmware 1.4 available to download via Apple.
I can see that there’s more and more people with failed flashing attempts here and on reddit now.
Definitely seems there’s something wrong with the tools. I understand there’s a boot rom reconstruction alternative service , that could be potentially flashed directly via rom tool, but I haven’t found any tutorial on how to actually reconstruct the firmware. Would be happy to try it, by inserting the unique numbers of this board onto a new firmware file. There’s someone charging for this service, but that would cost the same as what the computer is worth right now. It’s definitely not worth it.
If someone could help with a 4.1/5.1 2024 revised flashing tool (last revision was in 2022), or with a tutorial on how to reconstruct the firmware with uefitool so that it can become a 5.1- and unlocking cpu/ram potential, that would be very much appreciated. Going nuts here right now.

BTW: Noticed that an unflashed 4.1 runs HighSierra when booted from a drive that was installed in 4.1>5.1-flashed MP.
What would happen if I started to install Mojave into this machine? Can some of the firmware updates be skipped over? (straight from MP41.0081.B07 to 144.0.0.0.0.)

No, won't work. Simply try on your own
The Mojave installer will recognize an unsupported machine and deny the upgrade or clean install. Fresh installation to empty drive isn't possible with 5.1 until the firmware is updated to 144.0.0.0.0, the updater can do this only from a running macOS.
High Sierra works, if the drive wasn't converted to APFS, all firmwares for 4.1 lacks the APFS driver, so you're unable to boot from APFS-formatted drives. To my knowledge, APFS is mandatory for startup drive since macOS Mojave.
The netkas-tool is not maintained anymore, i guess the only way to update 4.1 to 5.1 can be done with a bootrom rebuilding.
Warning: NEVER try to flash a generic firmware file (.fd extension) until you made several bootrom dumps, this will delete all individual data inside rom and harm logins or registration for some services and software!

A question about this:
"Warning: NEVER try to flash a generic firmware file (.fd extension) until you made several bootrom dumps, this will delete all individual data inside rom and harm logins or registration for some services and software!"
What exactly happens with a generic firmware? If a machine is new to a person owning it now, does it matter?

Generic firmware files are usually used only for updating; the flashing tool will not erase the whole content of the chip while updating and leave the unique data at its places.
As i explained yet: Some of the data like serial no. is needed for Apple services and may also used for licensing software.

As it is been said often: be very careful when doing this yourself, almost every little error in the process will lead into a brick. At least check it with the tool I made https://github.com/Macschrauber/Macschrauber-s-Rom-Dump or / and with Uefitool.
My Dumper will refuse to flash when a dump has obvious errors. But it can, of course, check only for bad checksums, wrong serials, wrong positions, etc, but it can not find logical errors.

Hi guys, this is my first post. A while ago, a friend gave me a Mac Pro 2009, and I want to upgrade it from 4.1 to 5.1 firmware. Here is the machine information:
OS: OS X El Capitan (10.11.6)
CPU: 2x 2.26 GHz Quad-Core Intel Xeon
GPU: GT 120
Model: MacPro4,1
Boot ROM: MP41.0081.B07
According to the information on the Internet and following the tutorial of The House of Moth step by step. First, I entered Recovery and disabled SIP, and then mounted the dmg in the system, and opened the Firmware Tool to upgrade. Finally, the word "Finished!" popped up. I shut down the computer, then held down the power button until the power light flashed, and then a long startup sound was heard. The computer turned on, the optical drive did not eject, and the computer directly booted into the system, still keeping the 4,1 firmware. I tried this process at least 5 times, but it didn't work.
For my computer, I cannot use OS X 10.8, 10.9 to update the firmware because the Firmware Tool will prompt a 5530 error.
I have tried searching for many solutions but with no luck. Hope someone can help me, thanks in advance.

Hi guys, I have successfully upgraded my 4,1 to 5,1!
This is working for me, I just have to change the script. Thanks for davidkfraser's advice.
So the final script is:
Follow every step in that thread, including using DiskUtility to convert each disk image to a new read/write image, RENAME the mounted disk, disabling SIP, and double-checking the SIP status using the command csrutil status.
After everything is done, shut down the PC, hold the power button, don't let it go EVEN you saw the flashes and the long beep, by keep holding the power button, the optical driver will come out indicate the firmware is valid, give like 5 seconds, push the drive back and another 5 seconds, release the power button and give it a sec, it will restart again and boot into OS X. Now it should be 5,1.
Reverse back to 4,1 should be the same, since we have replace both 2009 and 2010 EFI, instead doing sudo UpgradeEFI2009-2010.sh, we do sudo DowngradeEFI2010-2009.sh
Even if you're in El Captain(which is in my case) and the firmware tool works fine, changing the script will give you a 5570 or 5530 error that allows the ramdisk to remain mounted, so don't worry.
If any of the terminal step you got permission denied or operation not permitted, try chmod 777 the directory and DOUBLE CHECK YOUR SIP!
