MP 1,1-5,1 MacPro 4,1 to 5,1 firmware problem! Just doesnt work!

[chrisjacksontech]

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
