Message on boot saying start work loop initialise service still waiting for root device

HI there,

I'm totally new to this, and been playing around for the last couple of days and got as far as boot working with the error message above, or it just loops. I've tried USB3 and USB2 with no luck. Any ideas please?!

Attach your EFI you're using to boot!

I can't - says it's too large for the server to process. (27.2MB)

Use Google Drive to upload.

Your EFI is not as per the guide.

Make the following changes to your configuration:

- Remove SSDT-EC, SSDT-USBX.
- Disable ResetLogoStatus
- Disable FixupAppleEfiImages
- Kexts sorted order is not correct. Mandatory kexts should load first.
- MacPro7,1 is a poor choice. Use MacBookPro16,3.
- Add GenericUSBXHCI (AMD fork). You can grab it from the downloads.

Once you're done with the changes, save your config.plist. Restart the system and reset NVRAM twice. Attach the new PR files.

Thanks for your help. I did this and it's still performing the same way - any ideas?!. I've uploaded the EFI - https://drive.google.com/file/d/1IdvFJAchyDaOwM7nlCbchb1q54HcQsUj/view?usp=share_link

Still wrong. You were supposed to keep the SSDT-EC-USBX-LAPTOP. Not sure why you removed that and using other one. Was the instruction not clear enough?

Also, what macOS version are you trying to boot?

That's what I currently have. If this is not correct, then what changes need to be made? I'm trying to boot Sequoia

Keep the SSDT-EC-USBX-LAPTOP and delete SSDT-USBX.
