"Yellow yield sign and an exclamation mark in the middle of it"

Just rooted and,a yellow yield sign and an exclamation mark in the middle of it "System software not authorized by Verizon Wireless has been found on your phone. Please turn off your phone and go to the nearest Verizon Wireless store for help".

I found out how to get around this (go into odin then press the down volume key to cancel then till phone boots up) but I can't get into the root recovery menu with out this message popping up. I can't even do a factory reset. I only have root with busy box no ROM was installed, well its custom.. but you know what i mean. Can anyone help me?

I'm on 4.1.2 with verizon samsung galaxy s3 sch 1535
