I've had a rooted Evo 4G LTE for 14 months now ... my first smartphone ... but have decided to move on and upgrade. I still love the phone, but I'm moving on because it's flashed to work on Page Plus (Verizon MVNO) and I can only get 3G, plus I'm only grandfathered in to be able to keep the phone on PP, and if I should ever get kicked off that network, I can't get back in.

I've got an HTC One M8 on the way, that I bought on Swappa. My question ... what do I do to get all vestiges of "me" off the Evo, as far as clearing my data, accounts, etc., before I do something with it?

I've researched the "standard" process for doing this, I was just wondering if since this phone is rooted, I need to do anything special. I basically was just going to toss this out on the Swappa Boneyard or eBay and see what I can get out of it, not going to put any money into unflashing it because I don't see the point given the pittance these phones are going for right now. I just wondered if there's any way to keep root and keep the ROM I'm using on there (Yankee's ROM) when I do the reset, although I fear if anyone unflashes the phone it might mess that up. I'm still sort of a newbie on such things.
