Flashed 360 - Quick Question

Hello!

I've had a flashed xbox 360 almost 9/10 months?... I recently got my hands on a copy of MW2 and completed the single player campaign with my ethernet cable unplugged.

I have just been told that my uncle has been console banned, and i was wondering, on tuesday im going to reconnect my Ethernet cable, will i also be banned when i do this? If so, would waiting for a liteon firmware update before connecting my ethernet cable keep me from being ban free when i do eventually connect my ethernet cable


Thanks alot
