this is my EFI file, hopefully that can solve the problem.
Have you tried with the default settings that are in the config? Because that's the only difference I can see.

Confirmed working with Lenovo ideapad 330s 15iKB with Broadcom BCM94352Z
 
Hello, I've downloaded your EFI as the laptop you used is similar to mine (Ideapad 330s 15IKB), but I'm having no luck in getting it to the install screen (btw I once got there but did not go further). The laptop always reboots after the Apple logo shows up. I did configure the config.plist file with the generated SMBIOS and also tried keeping only necessary kexts & removed ACPI patches but no luck. The EFI is basically the same as yours from github. Can you help me regarding this? :D

Maybe try this guide and EFI for install.


Make sure you make the changes to config.plist as stated by the guide. Once you have installed Big Sur, try the EFI posted in this thread for ideapad 330s 14iKB.

Thanks, will try later today.
 
Hi again,

all working well, even got verbose disabled.

Is there a way to enable the boot chime?
Had a look about online but I cant seem to find how to enable it?

Thanks :)
 
So I have noticed something..it's not a deal breaker but it is annoying nonetheless. The screen tends to flicker when I am watching videos full screen. If i move the mouse and video UI come on - the flicker but it comes back again as soon as the UI disappears. I have a dirty fix of sorts for it by changing the color profile of the display to some of the profiles not for the laptop's display but it usually washes out the colors. sRGB profile works but the brightness tends to change in full screen.
Any ideas? is it anyone here having the issue?
 
Any idea whats happening here? Seems to happen sometime after deep sleep.
