without knowing im going to assume you got cwm from something like rom manager..probably not a good move. sounds like you are stuck in a boot loop. and depending on how far along development is on your device..if there is any development..you may not be able to get out of that boot loop.
this is the closest thing to help i can offer you,and i do not know much about the site or the utility it offers. but your device appears to be supported. maybe with any luck,lg tool can help reflash your phone to orignal state via downloading the correct update or original install. all i can suggest is visit this site and download the lgtool and go from there.
