You'll need to set up a Google account, remove the one on there, and put in your account. Simple enough.
So did you ever figure out if the reset erase the flashing info? I have a hero, and am having a few problems with my messaging and phone apps constantly force closing. It was working great until I screwed with it. If I can get it back to where it was right after i had it flashed, that would be great. Let me know if you figured it out thanks
