Busy timeout "MacbookPro8,1" Mojave

Hi, I updated my dell e6420 from sierra to mojave directly from appstore, installation completed successfully but now I have this issue booting. In sierra, I used MacbookPro8,1 smbios and it worked, but it seems that mojave removed support for it, so at the first try I got this message. Then I replaced /System/Library/CoreServices/PlatformSupport.plist with an old one, but still got that message. Also tried using a different config with MacbookPro12,1 (or something similar) smbios and still got busy timeout. Any solution?
