RUU.... I don't think there is a way to back s-on... I know multiple people if you send your phone for warranty repair and your s-off they will still do the warranty... But use the RUU off the HTC website.... http://www.htcdev.com/process/legal_download/152
What are you doing anyways? Why do you need everything back complete stock? Warranty?
