Default Getting my optimus l7 with cm10

Hello, i`m trying to make my device work with cm10. Everything works fine with flashing the device and installing cm, and gapps. But when i`m finished, i get some errors like "google play has stopped".. + it recognize my simcards, but i can't get my network to work. In network area it sais "Network unknown:0". I`ve tryied many solutions like v20 basebands, another rom, but nothing..any ideeas to solve the problem?
