But when I try to connect my phone on fastboot mode (connecting the USB while volume(+) is pressed) the computer recognize the device immediately how "qhsusb_dload". When disconnect the device after that, the phone only turn on with Power and Volumen(+) keys. After that, the phone still working ok, the problem only is present when try to connect to Fastboot mode. As extra information, I can connect the phone in download mode (connecting the USB while volume(-) is pressed) and the computer recognize the device how "S1 boot download".
I'm running on Windows 8.1 pro, also I try on Windows 7 professional, both of 64-bits.
Sorry for bad english, I speak spanish.
