Hello,

5570 ERROR means it the firmware app can't download the image from apple website.
Maybe Give a try with https://github.com/pigsyn/MacProFirmwareToolUpdate/releases/

(a) Get the 5.1 updater package

(b) Get the tool zipfile

(c) Double-click the 5.1 updater package so the Disk Image is Mounted

(d) Unzip the tool, Run the tool

PM sent, read the instructions, look at the photos, disable SIP, do the BootROM dump etc.

Hi tsialex,
I have exactly the same Problem as Flocarino...
I´m going bananas the Firmware Update just won't work.
Used my old HDD with El Capitan and even did a clean install on an SSD
Tried all the things mentioned above -> always error 5570 -> crazy .

One thing that I also realised that i just also can´t boot from an USB Bootdrive (tried 3 different brands)

Would you be so kind as to send me the mentioned reconstruction 140.0.0.0.0 for your MP4 and instructions?

Many many thanks

Please read the first post of the thread:

MP5,1: What you have to do to upgrade to Mojave (BootROM upgrade instructions thread)

Please fully read this first post, you will probably find that you have one or more problems described into the various notes below. Mojave will only install if you have upgraded your BootROM to the current release and your Mac Pro have a Metal capable GPU*. If you are trying to install Mojave...

Pay attention to the notes, see what is blocking your upgrade.

Reconstruction is a complex process, takes a lot of time/effort, and it's a last resort only.
