[Success story] MacBookPro5,1 (2008 15" MBP) - Monterey installer does not work with current OCLP, but does work with OCLP 1.4.3

If anyone else has a MacBookPro5,1 (the 2008 15" MBP) and you are constantly encountering the no boot / apple.com/support/mac/startup error screen when you boot from a Monterey installer created using OCLP, download OCLP version 1.4.3 and then redo the EFI / Build OpenCore. It will work!
