I was trying to install a new rom on my verizon s3 and somewhere i messed up! I now have a message on my phone that comes up saying "system software not authorized by verizon.....take to store". I cant even boot to recovery by holding up, home and power. Im wondering if there is a way to fix this myself, and also if i take my phone to verizon will they help me even tho my phone is rooted? Any insight or help on this would be greatly appreciated!

This procedure might be overkill, but it should work for you:

I would try a normal ODIN flash first; see the sticky.

Yes I soft bricked at least 5 times now, for some reason I can't flash any roms . But follow the Odin flash process u will be alright .
