Killed my D800. I could really use some help! topic

So I tried installing Cloudy G2 3.0 the recommended way, with the patches and stuff. I initially did a dirty flash from stock lollipop but the ui wouldn't load to I went for a full wipe. At some point during the install, something messed up and I was sent to fastboot. That's all I could get to, so I wrote over the .img files to restore the partitions and now I have access to the factory reset menu and the hardware key settings menu. The factory reset menu just freezes at "factory reset processing" if I try to use it. When I boot normally, I get to the LG logo where it freezes. No pulsing light or anything. Plugging it in at that point allows the computer to recognize it but no adb or fastboot options. LG Flashtool recognizes that the phone is there but won't flash any .tot file. If I try a D800 tot I get wrong model and if I try a korean tot I get a cross dl error. I really need help, I screwed up!
