Catalina + B360M-A + Sapphire 5500XT Nitro+ keeps Rebooting. Not able to launch installer.

Good morning,

I am opening this thread as I am now desperate. I think I've read all possible posts from Tonymacx86 and reddit but wasn't able to make it work...

I decided to open a thread here as no one is helping in Tonymacx86 ... Hopefully the reddit community can..

  • Motherboard: Asus Prime B360M-A
  • CPU: I5 9400F
  • GPU: Sapphire RX 5500 XT Nitro+
  • Ram: Corsair Vengeance 2x8G

I've followed "Unibeast" method to flash my 16GB Usb2.0 pendrive. I've tried different combinations of config.plist and kexts (USBInjectAll.kext, USBPorts.kext, ...).

Most important parameter I understood I had to configure in the config.plist for the graphics was "agdpmod=pikera" which I did. But the system keeps rebooting when trying to launch clover...(see image attached)

Tried different USB ports but all same...

I bought specifically this 5500xt as it was referred as working in Catalina by community but I am starting to think it is maybe my motherboard?

Below my EFI:

Please, help me to have this working. I am ok to go for Mojave but I think this GPU is only supported since Catalina (navy support).
