Don't know if you've heard about it yet, but if you type stuff in to this called google you can find all sorts of stuff. fastboot windows 8
Already tried those methods of installing drivers in Win 8.1 x64, nothing works. Adb works fine, but fastboot drivers doesn't get installed and we still see those unknown E7 devices as mentioned above. If someone else have all drivers installed, kindly share us the method to install all drivers properly. Another reason to hate this driver enforcement crap!
Did anyone figure out how to get fastboot working? I am having the same issue. ADB works fine when the phone is off (battery charging logo on the screen) but when I go into fastboot mode (the red gionee logo displayed) the phone is not recognized by ADB or FASTBOOT commands.
^^ That issue can't be resolved under Windows 8.1 64 bit, I tried almost everything but vain. Only way it can work is to install Win XP 32 bit, and then try with the drivers posted above. It should work hopefully. Problem is my SSD is quite low on space so I won't be able to dual boot XP. If anyone else can try this on XP, let us know.
