Rooted Verizon S3 on TMobile- Want to update

[radhi19]

so i have a rooted verizon s3 on Tmobile right now and my current Android version is 4.1.2
I want to update my system but I'm afraid that because I'm rooted and on TMobile on a verizone phone I'm going to lose everything

is there way to update without having that happen?
any help would be appreciated, thanks in advance

You will most likely lose root if you update
