[HELP] Lg Optimus L3 E400 Bricked topic

Hello!

I Tried To Install A Custom ROM But After Its Successful Installation Using CWM When I Rebooted The Fone it didnt booted!
No Key Combinations Work ETC!
But When I Connect it to the pc i hear a sound on windows!

I Also Checked On Device Manager IT Shows Some LGE AndroidNet USb Serial Port(COM15)

Please Help Me! I Don't Wanna Go To The Service Center!

I Bought The Device Like 2 Or 3 years Ago I Don't Remember And Also The Device Is Rooted So Warranty Is Void. Please
