MP 1,1-5,1 Mac Pro 3.1 FirmWare upgrade to 7.1

[theodor12]

Hello,
recently I bought a Mac Pro 3.1 2008. I’m not using it for something super intensive. I uust wanned to have a Mac for cheap. I’ve had in plan, to use some DosDude patchers to upgrade the Mac to macOS Big Sur. But unfortionetly, DosDude didn’t do a patcher for macOS 11. So I tried using some other patchers, even ones made exactly for Mac Pros. But they somehow didn’t work either.
So I thought, I could try upgrading the Mac Pro firmware to a newer version. But I’m wondering, Mac Pro 5.1 officialy suppors macOS Mojave. But I somehow need to go to macOS 11 or Catalina. Is there a way to upgrade my Mac Pro 3.1 firmware to Mac Pro 7.1? The currently newest chease-greater Mac Pro?

Not even remotely the same hardware so it wouldn't work.

Seems you don't have an understanding of what a firmware is. Probably you saw that MP1,1 can be flashed to MP2,1 and MP4,1 can be cross-flashed to MP5,1 firmware and thought that the same would be possible with a MP3,1. It's not.

You can cross-flash MP1,1 to MP2,1 and MP4,1 to MP5,1 firmwares because the hardware is 99,9% the same for that models. Apple used same Nehalem X58/5500 platform from early-2009 to mid-2012. MP3,1 is a one year off that can't be flashed to anything.

Anyway, MP3,1 firmware is stored on a 16MB FWB flash memory and MP4,1/5,1 is on a 32MB SPI flash memory. Just this fact makes it impossible to do what you want.

Sorry if I intrude on this discussion, but in my mac pro 3.1 from 2008, I think I read u = in this forum some time ago that you could update the firmware to version 4.1, is it possible or do I remember correctly?
And if it were possible what advantages could I get?
thank you,

Nope. You are mistaken MP4,1 to MP5,1.

MP3,1 can't be updated to anything - it's written on the post you quoted above, btw.
