I don't think anyone has this problem, but it's worth posting it. I flashed UD8, UD rEVO theme, and chevy's 1 ghz ulv. I backed up the rom after it was done restoring my applications, but it wouldn't boot up after that. I tried flashing a higher voltage kernel, kernel from a different dev, and it still didn't boot, it looped the boot animation. My phone has no problems handling whatever ULV or LV speed kernel you throw at it. Has anyone else been not able to reboot?
