i think you kill the lg, because your l7 is the second edition, and you use a rom for the first l7 edition, try to flash a original rom of your mobile, download from http://lg-phone-firmware.com/index.php?id_mod=21:(:(
it works perfect, very smooth, sorry for mi english, its very nice, but the only thing i cant find, where is the flash option in camera, i look everywhere but cant find it:(:(:(, i recomend it :o:o
