Take it to a different cvs. I returned one without a reciept and they gave me store credit. Since that one was for my son and he decided he didnt want it (he is 4 1/2 going on 12) he got the gift card and went crazy getting 50% off gifts that they sell just for christmas.Yep. it ruined my wifi, too. Everything was working fine until I did the update. Returning is not an option for me since I've already returned one (would not turn on) and they said I'd just get my $$ back. My hubby loves it--what can I try?
