Monterey install trouble : “A required firmware update could not be installed”

So I am installing macOS Monterey and it installed the first half, and after the first restart, it boots up to a screen saying that a required firmware update could not be installed. I’m not quite sure why. Dell Latitude E5450 i5 5500U 8gb RAM MacBook Pro 12,1 SMBIOS Things I did after this: - I changed the SMBIOS to another serial and board number (still MacBook Pro 12,1) - I changed AdviseFeatures to True - I kept UpdateSMBIOSMode as custom and changed the CustomSMBIOSGuid to true

Even after doing this the problem hasn’t been solved. Does anyone have any solutions for this? MacOS Big Sur is installed successfully however with its own EFI. (Is it possible that this EFI is interfering with the one in the USB installer and causing this problem?) Thanks in advance
