[q] i really need help here please

I am a long time fan of this forum and have rooted many phones. I had a # symbol on my notification bar wanting me to update my superuser. I have some vision problems due to a stroke 3 months ago and hit the wrong thing and hit the update recovery and I got the Yellow triangle saying the Verizon detected unauthorized software. I know some of you are going to tell me to search for it, and I have done that the best I can. Like I said I had a stroke and it has affected some of my vision and makes my thinking a little cloudy at times. I hope someone can tell me there is a fix for this and would be so kind as too point me in the simplest way in getting my phone restored. I am not helpless, I could just use some help from the community here if there is a fix. Thank you for your help and understanding
