MP 1,1-5,1 Mac Pro 5,1 had main boot drive accidentally encrypted

[KPKING]

I am in trouble. As I was trying to use a metal card and go to Mojave on my 5,1 I inadvertently encrypted my main boot drive High Sierra) it created a user name that is jibberish and my password did not work. Then underneath the jibberish was my real user name but again password did not work. Every other drive I boot up in it prompts me to enter a password to “unlock” the HS drive. Can anyone instruct me how to remove this encryption. The terminal instruction are not clear to me

Inadvertently? One needs to unlock System Preferences > Security & Privacy > File Vault and press the Turn On File Vault button. Did you save the recovery key? Otherwise, did you "inadvertently" encrypt your boot drive using some other software?

All I know is it created some jibbers as a user name. I was made aware of that when I went to reboot after dealing with Mojave patcher. I did not see any firevault key. Should I turn fire vault back on? I have it off now

MP 5,1 supports Mojave, no “patcher” necessary, so I’m not quite sure what you’re trying to do. Is your firmware 144.0.0.0?

I could not get it to advance to 144.000 and I tried the button hold many times with metal card installed

It’s all just so time consuming and stressful. Thankfully most of the data is in the cloud. But I would love to get that drive to boot again
