Help topic

So i guess i finally got myself in a jam. i have flashed man many ROMS,but recently i hit factory reset on the bootloader screen (i think that is what it is called) instead on recovery and it seems all of my memory has been wiped out. So I have spent many hours trying to figure this out but i am stuck in TWRP with no recovery or ROMS to flash. I have also tried ADB sideload but i keep getting "fail". I am out of ideas. please help.

Thanks!
