If anyone have a good idea please leve me a reply?
I give a thanks to all that are helping me to solve this problem.

Take your SD card out and connect it to a computer running Linux (Ubuntu for example). There you will be able to see all partitions and you will be able to find your configuration files.

where i can finde the configuration.yaml under which folder??
