As I understood, you may wanted to flash ElemantaryOS for debloating your phone, because, I think, in that ROM one would find anything special. Therefore, I would offer you to debloat your phone watching my video about this topic and using ADBAppControl:
But if you do this, be aware of uninstalling system applications and trust only yourself.

Hello, it seems like your recovery and os are broken. I also met this problem, when I tried to install a custom ROM by an incorrect way.
