@thephd@Sobex It can't make anything worse so you might as well try it! Fedora should have usable packages (you might need to select an older macOS version to restore since I think the latest builds triggered some issues that just got fixed but not released yet).
Can you still get into recoveryOS though? If you can then it should be fixable without DFU... (DM me if you want me to help troubleshoot ^^)
