Unable to update to Monterey from BigSur Lenovo u510

[giorgatzelos1]

Hi all! I have a Lenovo U510 which has run macOSX Snow Leopard 10.6 until macOS Big Sur 11.6.5 that i am currently running . Whatever i have tried though, (changing SMBIOS, Quircks etc) i never managed to reach Monterey installer UI. Can anyone help me please? i attached a boot log along my config.plist. i tried a lot of similar laptops' EFI and made changes to mine but nothing...So after 1 month of trying i decided to reach the comunity for help.

After lots of tests and after i succeded installing Monterey only with Clover, not Opencore at first, i rebuilt Opencore from scratch and i finished my build.
