So, I had bought MacPro 5,1 recently that came with High Sierra. I used OCLP 1.5 and was able to upgrade it to Monterey without any hiccups. It worked fine. Recently, I got the notification about OCLP 2.0 and I updated it (probably the worst mistake :/). When the system restarted, it loaded High Sierra back (since I did not see a boot picker in the start up (however, this was normal with Monterey using OCLP 1.5), I was not able to select the appropriate boot loader). In panic, I tried to do a fresh install of Monterey with OCLP 2.0.0, and then the system would not turn on. The monitor would only blink (usually it stops blinking when its getting video input). Reading through other people's experience, I tried NVRAM reset, which probably make the issue worse. Now the system would chime on start up and eventually turn off in 2-3 minutes. Someone suggested to perform 4 NVRAM resets. I tried it and for once it turned off but after 3-4 h, I powered it up, and I saw the white screen, apple logo with progress bar and back to High Sierra. Now, to get back to Monterey, I believe I should clean up OCLP throughly and do a fresh install (OCLP 1.5 or 2.0.1). Would that work? and what would be the best way to go about it? Also, what cautions should I take before I do anything else. I also wonder what went wrong that the system worked now? I am also worried about going back to condition where it does not turn on (my major concern!) Would appreciate any help.
Here are system's specs:
