    Have you installed the HTC Drivers to your computer?

    Do you have USB debugging in the phone enabled?

    you may need to tap the build number several times in settings/about phone/software information/more to make the developer options appear. once youve got usb debugging set,here are some additional troubleshooting steps:

    troubleshooting connectivity issues:
    *make sure you have changed to your adb/fastboot directory!
    *make sure usb debugging is enabled(checkmarked) to use adb in the OS
    -try a reboot of the PC
    -try different usb cables and ports
    -dont use a usb hub
    -dont use usb 3.0
    -make sure nothing capable of comunicating with the phone is enabled and running. htc sync,pdanet,easy tether,and even itunes have all been known to cause issues.
    -windows 8 has been known to have issues. try a windows 7 or older machine

    failing the above,
    -i use these drivers for fastboot and adb(donwload and run as admin): http://downloads.unrevoked.com/HTCDriver3.0.0.007.exe (mirror)

    failing that,try manually updating the drivers in the following manner:
    -put the phone in fastboot mode(select fastboot from the hboot menu)
    -open device manager on the PC
    -plug in phone,watch for it to pop up in device manager.
    -update drivers with device manager,pointing the wizard to the extracted
    driver download folder from above

    note that you can check the connectivity of the phone,and make sure drivers are working by in the following manner:
    -open cmd window. change to directory containing adb/fastboot utilities

    -adb with the phone in the booted OS,usb debug enabled,enter:
    adb devices in a cmd window

    -fastboot with phone in fastboot(not hboot!),enter:
    fastboot devices in cmd window

    in either case,a properly connected phone with working drivers installed should report back the phones serial number.

    So I downloaded the drivers, the firewater file, and the platform tools I use for adb and fastboot onto my flash drive and I'm going to try this tomorrow at my cousins house and see how it goes

    OK so I felt like my cousins laptop was trolling on me, I tried to manually update the drivers but the device manager never showed up and I still had the same problem Dx
