Help Phone P500 won't start up

Hello, i updated my lg p500 trough LG PC SUITE(official update), but now, the phone won't start, it just stays on android logo for an eternity. basically it wont start. I tried many thing from google and said that you must plug your usb, but how can i plug my usb when my phone can't be connected to the pc. Weird, hoping for an answer. And no rooting. Original phone, bought it 1 week ago:(
