and i already gave you a more in depth link for doing it from sd card.

yeah i just tried it and i failed. after i found the rom i wanted it came with a bunch of files and only one nbh file named RUU_signed.nbh, so i ranamed that file to RALPHIMG.nbh and put it in my sd card (deleted the unlocker.nbh file that was in my sd card's root folder because it had the same name as RALPHIMG.nbh) and then i did the bootloader thing (power + volume down + soft reset) and it just gave me the same RGB screen.

i currently have a custom rom installed on my phone, do i need to get rid of it first or does flashing do that for me?
