LG Muziq / AX-565 / UX-565

my phone said there was a new version (v-5) available and would i like to update. so me being the guinea pig, did so.

wow.

what a mistake.

now all i get is a white display w the sprint power up logo on the sub and that's it..!!..

anyone have any ideas wtf happened?

btw- i tried all the normal troubleshooting. i.e.- pop off battery, etc...
