Rooting the HTC Wildfire is a very easy process. We have only done this using Windows (which requires HBoot) and have had a flawless experience. Anyone with an HTC Wildfire knows that rooting it will unlock its full potential and it is easily one of the top 10 phones on the market to date. Thanks to Unrevoked rooting the HTC Wildfire is a very easy process.
If you are a Windows User you must install HBoot Drivers before running Unrevoked.
unrEVOked modified USB driver and unzip it where you can find it. Turn off your phone, then boot it into the HBOOT menu (hold power and volume down button).
On your phone, you will have to select HBOOT USB at that menu (press volume down four times then power).
Wait for the screen to flash a “SD Checking” message before pressing buttons; otherwise, the phone will ignore keystrokes.
Connect the phone to your computer via USB and wait for the phone to say HBOOT USB PLUG on screen.
