I just tried now and it is still not booting. Maybe all my EFI folder is not good, I will explain you how I made it and can you tell me if I did something wrong ?

 

1. I downloaded and extracted EFI_v5028

2. I added everything from E7440_Hotpatches.zip

3. I added everything and replaced everything from E7440_Mojave.zip

4. I updated AppleALC and Lilu kexts

5. I updated clover to the last version, and after with the version that you sent to me (5092).

 

Is it the good way to have the final EFI or maybe I did something wrong ?

Thank you a lot man you are the best !!!! 😃

It's now booting on Catalina, I had no wifi so I added AirportBrcmFixup.kext in EFI, I also changed Voodoo kext because my pad wasn't working good. So I took the one from Hotpatches and now I will try to reboot on the three systems. I will tell you if there is something wrong.

For the moment, on HS everything is working good. 

 

EDIT : On Catalina sound !!! And wifi but no bluetooth (I think I will find the solution, I need kexts for my wifi card)
