Hello @sizar .
If you are wanting to install Tahoe its necessary to remap your USB ports, USBToolbox and UTBMap.kext are not compatible in 26. USB functionality has changed and older kexts aren't formatted correctly and so will not work. You can try using either CorpNewt's excellent USBMap Master or Hackintool as both have been updated to accommodate the changes. You'd have to do the in Sequoia though.

Make sure you have OpenCore and your Kexts Updated to the latest versions.

Also disabling Whatevergreen.kext is often needed until install completes, but you also should par down your EFI to just the basic kexts. Bluetooth and Ethernet should be disabled again until install completes. Good Luck!

Hi, thanks for the clarification, that was with the tahoe raw file, now im trying to install sequoia with the recovery method and still dont have any luck with it, this time its a clean efi and config only the necessary files and kexts, it just stuck on the motherboard background/logo after selecting the UEFI: Flash Drive from the bios.
edit: i just edited this reply so i could upload the new efi folder thats for the sequoia recovery method

If I understand you correctly your flash drive never starts booting? If so it sounds like your flash drive is incorrectly formatted and or your EFI folder is not in the EFI partition to be able to be read. These instructions are for how to format the drive using a real Mac.

STEP 2: Prepare Bootable USB Drive
This step extracts the Installer contents, then installs bootloader to the USB stick.

1. Insert the USB drive
2. Open /Applications/Utilities/Disk Utility
3. Highlight the USB drive in left column
4. Click on the Partition tab
5. Click Current and choose 1 Partition
6. Click Options...
7. Choose GUID Partition Table
8. Under Name: type USB (You can rename it later)
9. Under Format: choose Mac OS Extended (Journaled)
10. Click Apply then Partition
11. Open /Applications/Utilities/Terminal

If you have to use the recovery method in Windows makes sure you complete those steps correctly

Beyond that your EFI folder has a number of issues I tried to correct for you:
I disabled SSDT-CPUR.ssdt as your board should not need it
I changed some various config.plist entries to match the Dortania guide and removed your serial numbers and changed your system definition to MacPro7,1 which is a better choice.
