I rooted my evo using unrevoked, months ago. A few days ago, suddenly, I got the message processcom.android.htccontacts has stopped unexpetedly. I also cannot access the market. I have cleared the data, through, power up, holding down button, clear data. Is there a total factory reset that I can do, that will return my phone to what it was the first day? Not just clear user data, but put back all the sprint data. I have heard of the facebook app causing this failure, but I took that app off. There has to be a total reset. Thanks for your help.
