I don't even know where to start. Should I start with "searched but wouldn't find", with the fact that you didn't tell us your setup or with how you didn't tell us how you want to boot it up?
I thought of linking you to the "Noob" video as a ROM in disguise, but that would have been too mean.
The rom you're running is an SD one (at least that's what the name says), so I assume you're running either MAGLDR or on WinMo, and I also assume you want another SD build. If that's the case, you should go to the SD section, look for ROMs that say "720p playback" or simply "720p". I think by now all ICS run 720p, not sure about JB though. Download that and then (if you're on Winmo, simply place the rom on the sd and launch haret then clrcad) but if you're on magldr, idk how you're supposed to dual boot, if you know how then that's good. Otherwise, wait for other ppl or just use google.com .
Do you have a question about the HD2 ? Ask it here for an instant response.
