I have tried 2 times now, I'm using rear window defogger kit, I did the horseshoe method around the 5th L3 bridge, and it will boot to 5.5 mulitplier like the instructions say, but then when I try to make it anything else, AT ALL, it wouldn't post with the multi and I need to reboot back into 5.5. If I clean the unlock off it goes back to normal, but I mean, something must be down. Help yo.
