Hi all,
First time to post in this forum
My English is very bad too...
So, I have a Mac Pro 4.1, 2009, biprocessor, 2 x 2,26 Ghz, 6go Ram, GPU GT120. The Rom version was MP4.1.0081.B04, I upgrade the Rom to B07. I installed Mac Os El capitain in HD and Mojave using mojave installer (Dosdude1). I tried to several time to flash the Rom in El capitain using Firmware tool 2009-2010 it failed. I tried the same thing with mojave and nothog change.
I need some help

Did you tried the patched tool from El Capitan? https://github.com/EdsionL/MacProFirmwareToolUpdate

If the patched tool does not work, you gonna need a BootROM reconstruction.

Patched tool works the same way the original one. You can read about the usage on the iFixit write-up, the copy of the old netkas thread saved on the Internet Archive and also read the GitHub page instructions.

If you still can't upgrade, some early-2009s are impossible to cross-flash to MacPro5,1 firmware even with the patched tool, you gonna need the BootROM reconstruction service. I'll send you a PM with instructions/service fee/turnaround time.
