I have a spectrum 2 that I rooted a couple weeks ago. It has been fine, until tonight when I ran a system cleanup app. It asked me to reboot, which I did and now it just boots up to the LG screen with "security error" below it. I cannot do anything with it. I have tried the hard rest, and it goes through the prompts and starts to reset only to come back to the security error screen. My computer won't recognize it either through USB.
