Can't factory reset, can't install new ROM etc..

Hello I have a problem with my phone and I hope someone can help me. I can only boot to recovery mode via TWRP. The thing is that when i want to install new ROM, it says Updater process ended with signal: 11 and then: Failed to mount /cache (invalid argument), Failed to mount /system (invalid argument), Failed to mount /data (invalid argument), Unable to mount storage.

When I tried Factory reset it didnt let me cause same errors occured: Failed to mount cache,system,data.

I already looked on thore errors and there were solutions like changing file system to ext2 and then back to ext4, however when i tried it, the same errors appeared again. I cant even format anything and i think the phone is completely broken and unfixable at this moment. At this point it seems like theres no OS isntalled but i dont really know anymore. Can someone find solution to this or help me to fix this? Here is the terminal:
Here is the terminal
and here is what is says during isntallation of ROM:
Installation of ROM

Phone is XIAOMI REDMI 2 (TD HM2014813 2GB)

Thanks in advance for any ideas.
