A new site containing all known available ROM Update Utilities for the HTC series of phones launched today with the goal of putting them all in one, easy-to-remember location.
Currently, there are 36 phones served by the new HTCRUU domain, with my personal favorite lines of HTC EVO phones represented (Supersonic, Shooter, Jewel, etc). Multiple RUUs exist for most phones on the site.
ROM Update Utilities are programs that generally run on Windows machines and guide your connected phone through the process of installing new radio, firmware, boot software, and in most cases returns the phone to a state like it would be right out of the box.
One of the great things about most RUUs is you do not require root or knowledge of ADB commands, and they can be used to reset your phone to stock with all the latest over the air updates. This can be useful if you don’t have a working phone or WiFi but do have internet.
