I tried to install custom recovery using this manual "wiki.cyanogenmod.org/w/Install_CM_for_serranoltexx" (<- cannot use the link function, because it's my first post). I followed every step. At point 9 I have to make commands using the cmd. Unfortunately the result is an Error:
Failed to access device. libusb error: -12
I had two insecurities while following the manual:
- At point 4 I had to rename the recovery image but I'm not sure what the recovery image is. What I downloaded was a .tar.md5 file within a .zip. Do I have to rename the .zip or the .tar.md5? The renaming causes a change of the file type and I cannot really understand, why they didn't put the right file in that .zip at the beginnig...this step is a bit confusing
- To point 5: I deinstalled Kies and the device driver in the Windows operating system. Since I've done this, there are appearing two devices in the zadig.exe when I connect my S4. I installed the zadig driver for both of them.
Im using Windows 7 x64
I hope someone can help me, for this moment I don't know what to do further...
