Metropcs phone reflash?

[wiggles]

I got a mogul from craigslist already working with mms and internet last year. I left his house with it working. Since then I have installed and uninstalled programs and have messed up the registry pretty good i think. It's almost unusable. I would love to bring it back to where it was when i bought it. Is this possible? Will a new rom remove all the esn stuffs he did? I do not know if it is cloned or if he added the esn. Is there anyway to tell? Flame on...

it shouldn't hurt it, but if it does it's rather easy to reflash it with the plr, there are tutorials all over the net for this.
