[Q] How to flash modem.img? topic

I know. Total noob question. But so be it.

I'm on a really old baseband. I need to update to the latest modem. I downloaded the new one from the Reference thread, but I don't know how to flash it. I've tried the Flash2Modem.zip method and I can't get it to work.

Suggestions?

EDIT: I'm an idiot and didn't use the search function. I got it. Sorry for the thread spam.
