LG Enlighten getting an autorun error and rebooting, factory reset didn't fix it.

For the last week, my LG Enlighten will display the error message:
"The application AUTORUN (process com.lge.autorun) Has stopped unexpectedly please try again"
and a button to force close. This doesn't do anything that I notice, but anywhere between 2 and 20 minutes later, the phone will reboot.

I did a factory reset, and I still get the error. Also, the activation screen doesn't load, which I'm wondering if that has to do with the autorun feature.

My phone is rooted.

I'm curious if there is any way to manually re-install the OS from my computer or something.

HELP! Thanks!
