I can't install because "S1 fast boot device" doesn't show up. The only thing that show up in Device Manager for me is "Unknown USB Device (Device Failed Enumeration). Does anyone know what this means?

Yeah I've tried everything. Connects fine normally.
tried
different USB ports, 2.0 and 3.0
enabling USB debugging mode
uninstalling drivers
Light on phone turns green, but then just goes into charging mode.
I'm on Windows 8 64

Tried holdin volume up instead, light goes blue, but still get "USB device not recognised"

green is for flashmode and voilet is for fastboot mode and try with volume up button pcc uses flashmode so it tells you to put with volume down and did your phone is detected by pcc if not try installing pcc again and then disable windows verification and then try again

On my Windows 8.1 64-bit at step 8 it doesn't recognize it as S1 fastboot device.
When I select android_winusb.inf and click OK, it says the folder specified doesn't contain a compatible driver for my device, make sure it is designed to work with Windows x64-based systems.
So I can't. ;(
