Stuck performing fresh Sequoia install after first reboot during installation

Hi again,

after managing to get the USB flashdrive ready to install Sequoia, I'm getting this "preparing the software update" error message a while after the 1st reboot during installation process (using OCLP 2.1.2 on a MacBook Pro 9,1)

In this post it is mentioned that it's a common issue on mid-2012 MacBooks with Nvidias and/or SSD (which is my case) but the suggested solution of doing PRAM Reset didn't work.

I've also checking this post suggesting to change OCLP settings but, since my SSD is wiped I can't do it.

Any direction on what to do is highly appreciated.

Thank you again!
