In order to get the System files I recommend you should contact official Sony Service center. By the way tell me how you have deleted System files from your device????

Thank you. I'm trying to restore those files now, if it won't work, I will definitely do what you said. So, you wanna know how I did it? ok. So the problem was that after formatting my Walkman there was 11 GB free instead of 14.7 GB. So I changed Walkman from MTP to USB. Then I formatted it and suddenly I figured ALL the files would be deleted but it was too late. When it was MTP, formatting didn't delete all the files, so I was used to formatting......
