Updating HTC USB Sync driver
(0a) If you have Windows Vista x64 then you have to reboot your computer before you start this. Right as it is starting back up spam press F8 and when a menu appears select disable digital driver signing and continue booting as normal. Microsoft tries to "help" (so they say anyway) us by not allowing unsigned drivers to be installed on this operating system but lacks to tell us this when we get an error trying to install one! The funny thing is to get a driver signed as a hardware manufacturer all you have to do is pay Microsoft money. This is why there are so many unsigned drivers... why pay for something that does nothing? Go to the next step.
(0b) Place your phone into its bootloader. It is very important that you place your phone into its bootloader before continuing. DO NOT SKIP THIS STEP. Turn it off. Hold the volume down button while you press the power on button.
(0c) Follow these instructions but skip step 1. I know the driver files attached included here work on Windows XP, Vista and 7 (both 32-bit and 64-bit). Please use the drivers included here instead.
