I'm sad, I made a BIG mistake (for Sur

)
I managed to install Big Sur with your EFI v1, and it worked rather good (excepted wifi)
Then I saw you v2 folder and decided to redo a fresh clean install on a new disk after all trial I did with previous one
I created the media installer, mounted the EFI partition copied you EFI, wiped out all my disks (without backup, of EFI v1) and tried to boot
Unfortunately, system does not even reaches opencore selection. It shows the apple logo and immediatly reboots and loop
I checked bios parameter dozen of times, I'm completely lost
I tried to remake the installer key on a new key, re-download your efi, and one again started fresh but no luck at all
Do you have any idea on how to diagnose and maybe manage to go further ? maybe you can repost EFI.v1 so that I can give it a try ?
many, many thanks in advance
