I was able to get rid of the tampered banner today. I just need to unroot, so I can get my phone back in for warranty repair. My Bootloader reads out "software status official" on the top of my screen.

I have a similar problem that you have, but caused the probably using poor judgement. I was deleting system apps and bloatware, but I went too far and noticed I could not get my settings anymore for my phone. I did backups of all the apps on titanium back up on my SD card, but don't know how...
