Having trouble flashing ROMs. topic

Hi there. I've looked up and down but haven't seen anyone else with this problem yet, unless I missed it, then I sincerely apologize. I am rooted, ruining stock at the moment, and cannot get anything to flash properly. I've tried 2 different ROMs and they keep saying it wasn't made got v500, but for "awifi", but is from the TWRP I have. Can someone help me out or point me in the right direction? Thank you in advance.
