(This is my first post, sorry if I posted it on the wrong forum.)

Hello, I was trying to change my LG L40's bootanimation.zip, but replacing the file with proper permissions doesn't remove the default "Tmobile" animation. Rooted, I haven't changed the ROM, and if possible, I preffer a manual solution. Note that I have nothing to do with Tmobile, I bought it at normal price from an electronics shop.
