Trouble with Windows 10
Thanks for the info! I've been trying to get fastboot working on a HTC One X with Windows 10 and it's driving me nuts.
I've downloaded and installed the 4.16.0.001 driver in this thread. ADB works fine and I can get into what looks like fastboot from command window "adb reboot bootloader."
However, once the phone starts up again, "fastboot devices" returns nothing. In device manager, I get the yellow warning icon for "Android USB Devices" -> "My HTC." From there, I try to update the driver and I choose "Let me pick from a list of device drivers.." I see "My HTC" in the list and install that. Once it installs I still get the same yellow warning icon. I've tried uninstalling the device fro device manager and starting again, but it's still the same.
Any info on how to get this to work?! From the searching I've done it seems to be a driver issue but I'm at a loss at what to try next..
