Default Need a specific baseband

Hello guys! I have a LG F180S and before I screwed up my phone I had a M9615A-CEFWMAZM-2.0.12034 baseband and my signal worked flawless. After installing CM11 on it the baseband got changed and I had no network. Do you guys know where I can get this baseband as a flashable zip or something? Please I need it to get my signal back
