Sansa Clip Plus Format Problem

Firstly thanks for your reply. I have big problems. I am writing from Turkey. Sandisk isn’t selling mp3s officially in my country so i don’t have a option as service. To get to the main point, now i can’t format my mp3 player. I made a mistake as doing format within rockbox my clip plus. After format rockbox files has been deleted naturally. After format i tried to update my clip plus manually. I made it before and i didn’t encountered a problem. But at this time when mp3 player opens,  screen is freezing and it is lasting like this till run out of battery. I put in to computer it but i can’t format. So i decided to do it manually :cry: and deleted all files. Now it is opening and after sansa text sansa symbol seems and staying like this. Please help me. As i mentioned on the top i can’t send to service so i have to do it manually. I am waiting for your responses…
