Failed flashing, no os, wont connect usb only have TWRP

Hi so i've messed up bad. I rooted my SM-G925f yesterday which went perfectly, then I installed xposed and tried to install the framework which led my phone to not being able to boot. I tried to flash a stock rom which only fail on Odin and would only boot to the "use smart switch recovery screen", after that I tried to flash a custom rom which guided me to delete the OS at the same time, this failed too. Now I have a phone with no OS and when plugged into PC no USB connection, I still have TWRP but that's all.

Is there any way to fix this or is it now just a paper weight?

Thanks
