MBP 11,2 (2014) failed update to Sqeuoia

My MBP 2014 (16GB RAM, 512GB storage, i7 2.5Ghz) had a successful upgrade in Sonama . Then I decided to give a try to Sequoia . I am very sure I did the same as here step by step https://dortania.github.io/OpenCore-Legacy-Patcher/INSTALLER.html

But then after coping to harddisk and few flashes during installing, the OS starting procedure lingered, the bar paused in the mid-way with fan in long run.

Anyone experienced it before? What should do ?
