I imagine your phone is already unlocked?
In installed the drivers and I installed the fastboot executable, but what do I have to do next? If I run the fastboot.exe, it just quickly shows a CMD-window and then disappears.
I just discovered that, when I'm at the bootloader (I think it's called that way, the screen where you can select recovery), and I choose to reboot, I get the same 'error' as when I try to enter recovery.
Alright, I was able to flash a new recovery, using cmd, but now when I try to enter my recovery, the phone gets stuck at a black screen with Google logo and padlock...
