If you try and take a shortcut, good luck to you because the steps outlined below were the only way I could consistently load DD-WRT. Yes, what you are going to do below will be a real pain in the ass but I have confirmed from three separate RT-N12 D1 routers this does work. Then I realized I had to go through all the crazy steps as I had the first time to get it right. When I finally “thought” I had the process scaled down to a few easy steps it wouldn’t load and I bricked the router again (I actually bricked three separate RT-N12 D1s). Originally when getting DD-WRT on this router I bricked it a few times. Also keep in mind that DD-WRT is NOT officially supported on the Asus RT-N12 D1 so your mileage may vary.

The RT-N12 D1 is much different for installing DD-WRT than its predecessors, the B1 and C1. Asus RT-N12 D1This very lengthy Step-by-Step tutorial is for flashing your Asus RT-N12 D1 with DD-WRT.
