Accidentally formatted/wiped all of internal storage HELP!

So I wiped my nxa8qc116b internal storage all with advanced tab in twrp (yes I can boot into twrp) and now I can’t find the stock 5.0 lollipop rom nor stock recovery for it. I sort-of found a stock rom but have no idea how to flash/install it with fast boot (tried twrp didn’t work) I don’t know what else to do except toss it in trash and buy a new one for $70 please help!! Reply ASAP ?
