Lg Optimus G FLASHED WRONG BOOT.IMG

i was trying to install CWM (i had TWRP) but i used a wrong .zip and ended up installing the n7000 (galaxy note) BOOT.IMG

now the device wont show anything on the screen anymore, and it is only detected as a USB Modem

i have the original BOOT.IMG but i cant connect ADB to it

what should i do?
