I open my config.plist with plistPro (I don't have Xcode on this computer)
View attachment 446131
Something is wrong I think. Maybe Clover configurator did this ??
I replace "Z98AAA==" By "32cAAA==" and I get a Kernel Panic on reboot

Another thing is strange config.plist is the testing with "device properties", configBU.plist has none
Restarting with configBU doesn't work also.... I need to boot from o completely different EFI Folder from an USB key. I quite don't understand. Any explanation ?

Thanks again anyone for the Help

Watch the video, I edited the kexts to show you how. I included the edited kexts for Catalina version of the kexts. If you don't have Xcode then try these pre edited kexts. The video shows how to edit the kext but I only did one and replaced one using the folder provided. I did a video of the whole process but it was too large to upload here. What version of Catalina are you on. If you make a folder like the one I provide and right click and compress it then upload it I can dotes edits for you on your original plists. Note: They must be labeled in separate folders like I did so you don't mix them up. Watch the video a few times before attempting. Right click to get the "show package contents"option.

1. Make sure to run Hackintool to disable gatekeeper.

2. After adding/replacing the info.plists use Hackintool to repair permissions and rebuild caches.

3. Start with the 9500controllerkext only first to see if it shows up any different in Hackintool after reboot then add the others the same way.

4. After replacing the info.plist make sure to place the arrow/pointer over the "contents" folder and make sure you get both the "Authenticate" and "replace" prompts before the password screen. If you only get the Authenticate and not the replace then canceling do again.

****Disclaimer: warning this may screw up the ability to boot so test at your own risk. You may have to replace all these fixes with the spare kexts form a remote system t get back to where you are now.****

In fact, I don't use Whatevergreen, I do not have much experience on it

maybe you can use the debug version of the Whatevergreen to check the logs

the device-id, should be "32cAAA==",
you may test with the original device-id, (0x6FDF) "328AAA==", to see what will happen

@Gigamaxx
Thank you for the video and files
I made a progress :
I edit the info.plist (file like you show me in the video) of the AMD9500controller.Kext ➧ I reboot and it works
I replace the 2 other the info.plist with the ones you provided ➧ Kernel panic on reboot (even with safe boot)
Is there a trick to boot without those Kext ?

Is there a way that you make a video for editing the 2 other files ?
Big Thanks again

maybe you can try boot clover with stock config.plist
just set ATI Fake ID = 0x67DF1002, (disable Whatevergreen)
