Unroot HTC Vivid
I got an HTC Vivid a while ago. However, when I got , I looked into the software unlock method to unlock it. Doing so required for the phone to first be rooted. So I followed through some steps to root it. WORST DECISION EVER ! Since then, not only did the unlock not work, but the phone has gotten so slow and dysfunctional it is barely useful. I mean, everything else runs properly, except Calls and Text Message. i.e The phone isn't performing its right function.
Thus, I wanted to look into a way to 'unroot it' or at least just return COMPLETELY to factory settings. I want to be at least able to sell it and buy another. I've looked through and tried a couple of guides to remove the root. One seemed to work really well, until I restarted the phone, where the "Cleanup" window came back on, and the phone returned to its old rooted self.
Thanks in advance for your help !
