Smile [Q] Dumb Question

This might be a repeat, Buttttttttt, Im trying to flash a stock rom onto my gt n8013 and i cant find a .tar or md5 file of a custom rom. I downloaded android revolution which is what i really want to try and it even has md5 in the file name yet it is still a .zip Do i have to just download the stock rom....?

Im stuck in a boot loop and i have no sd card at the moment hence the use of odin, plus i never used it before and wanted to give er a shot.

Thanks
