My experience exactly. This is especially true when you have a Mac Mini attached to a TV for a "conference room" set up and you have to reset the Mac Mini for troubleshooting purposes. Forget the wireless option, the wired option is 100% reliable.

guys, please help.
I installed oclp on my Imac 2017, but i didn't use a usb drive, because i thought i didn't need it. At first i thought it did nothing, when i pressed build and install (some thing like that) on oclp. Then my macos started bugging out a bit so i restarted it and now i'm on the screen. Am i screwed?

"Build and Install" does not, by itself, do anything to your existing system.
Try restarting, while holding the Option key, to bring up your boot picker. Do NOT, at this point, choose the "EFI" icon. Choose your already existing system icon, then press Return to boot from that. You should then boot to your normal system. NOW, make a USB bootable installer for the macOS system that you want to use. DO NOT BOOT to that USB installer, until you run the Build & Install on OCLP, choosing the installer drive as the destination for that Build & Install.
NOW, you will have an external drive (your installer) that you can boot successfully. You will also use that external USB to let you boot to the your Mac, until you have installed the new macOS system. (You will reboot several times during the install. You should remember to hold the Option key each time you get a reboot, watching to make sure that the EFI partition is selected each time, you probably won't need to change the selection, as the installer should select that automatically--you are just monitoring the process) The upgrade install completes when you get to your desktop again. You will then run the OCLP, choosing to Post-Install Root Patches, Restart, then run the OCLP again. Choose the Build & Install, and install THAT on your internal boot drive. Restart again, and you should be ready to go on your new upgrade system...

Yes, that's correct.
You select EFI partition first, then press Return/enter, and you will then see the icon for the boot drive. That sequence is for loading the EFI, then choosing your unsupported macOS system.
If you have a working system (where you can successfully boot to the desktop), then you want to then go to the Startup Disk pane, to make sure your boot drive is selected there. Then, the next time you restart, it should boot without needing to hold the Option key.
