Just to clear the air. Yes, I am an idiot. I installed Clover on a Mac Pro 4,1. Bought the Matt Card, and now nothing happens. I'm in a boot chime loop (every 10 mins). Please help!!
Got a tip for us?

MP 1,1-5,1 Matt Card not working

More info. Plugged the A4054 Chipmunk Matt Card into the "Little Frank" Molex connector in the middle of the board. The label they sent me says that I got 820-2337. The arrow is pointed upwards on the matt card. What could I possibly have done wrong?
Ok, no EFI_DONE LED lit at all.
Do you have another Mac Pro (early-2009 to mid-2012, don't matter) to test the MATT card? Or you have a ch341a + SOIC/SOJ 8-pin clip to dump the MATT card?
Answer to the first question is no. 2nd question just blew my mind. I called the guy in the Netherlands that sells the Matt card, and he told me that he programs them in batches and no one else has complained about that specific group of Matt cards.
Can you provide detail on how I'd juse the 8-pin clip to dump the MATT card. Do I need a Medusa?
No, just a SOIC/SOJ-8 clip and a ch341a. You can't read the backplane SPI flash memory with the ch341a, but you can dump the MATT card with the ch341a and the clip. You probably can get one from Amazon for less than $20. Something like this one below:

So, if the MATT card is working, I should have a green EFI_DONE LED, correct?No, just a SOIC/SOJ-8 clip and a ch341a.

If the backplane is fully functional, with just the SPI flash corrupt, yes. The moment you install the MATT card the backplane SPI flash is disabled and the MATT card SPI replaces it while installed.
BTW, you need to power off and remove the power cord to install or remove the MATT card.
OK, making some progress. Trying to restore using the DosDude Catalina Boot USB patcher.
Bought a an EFI-flashed video card. Now I have a working boot screen.
I click on "Install Mac" nothing happens. Same for any of the other options. It gives me a black screen with a white Apple logo, but then it reverts back to this boot screen.

Why you are starting with a hacked install? Do you really like problems, no?
Do a fully supported install of HighSierra or Mojave with the Mac App Store installers, depending on the GPU you have.

Hey, no one said that I was smart. In all seriousness, I really appreciate your help. I had Catalina running on this system using the DosDude installer. Re-installing Catalina is not the way to go? I should go to Mojave and rebuild from there? So, after my catastrophic decision to install Clover, there's no way to do a restore that will preserve my file system?

What about doing the following?
Booting into the EFI partition and deleting the bootloader.
Long-term, should I just install Open Core and use that to upgrade to the latest?
Right now you have a mess to solve, remove your main disk, get an old HDD/SSD, fully nuke it and do a clean install via createinstallmedia USB installer of High Sierra/Mojave (this depends on the GPU you have). Later you think about your files/apps.
Btw, you will need to do the BootROM reconstruction to get your Mac Pro fully working again. All MATT cards are clones of a mid-2010 Mac Pro with serial GJ0340TXH2N and you will be blocked of iCloud/Messages/FaceTime when Apple detect the clone.
After you get your Mac Pro working, you can do that.
Is there a direct download that doesn't force me to pull it down in the App store? My laptop's version (Big Sur) won't allow me to pull it down, it's considered "too old to download".

OK, just so we're clear. I installed OpenCore EFI using Martin Lo's 0.75 package. I'm on the latest Mojave. Won't let me upgrade to Monterrey. "A required firmware update could not be installed". Should I still go with installinstallmacos? I did just get a new EVO 970 plus. No other drives in the machine. Just a GT640 video card. Samsung Black Magic tells me that I have the latest firmware.You can use installinstallmacos or gibMacOS:

Nothing to do with Mac Pro BootROM or MATT card.
Monterey changed firmware requirements from BigSur (and removed NVIDIA GPUs support), see on the first post of the OpenCore thread what you need to do/change on your config.plist to get Monterey support.
Ask further support on the OpenCore thread.
