Thank you for your help. I had the correct adb drivers, but I couldn´t do that.
Finally I have solved the problem with other recovery.
In the description Hackever says that we have to use the recovery twrp 2.8.
But that recovery doesn't work for me. With that recovery the program doesn't work in my phone.
So I have used CWM 6.0.4.7 recovery, and with this works properly.
Now I have my partitions merged.
Thank you.
