He's not stuck in recovery
actually not even sure he has clockwork.... I actually did this once on my other esteem. Forgot I didn't install cwr but just root, and the stock recovery/factory reset failed over and over and over. I forgot how I fixed it but it took a long time.
Op- Go to LGs website and go to mobile phones then find the Esteem. You should see a link for software upgrade/usb drivers. Click it and then download the LG update tool. Install it, then turn the phone on and see if the tool sees your phone. It'll tell you what sw version you have and if you have the latest (zvd) if it says there's an update, and not that you already have the latest update, click update and it'll take about 20-30 minutes and it'll update you to the latest version and return you back to 100% stock and it'll boot right up
