# Solved
I think it was a problem with the micro SD card.
Thank you for developer's advice.
I don't remember the exact model name, but I used 'Sandisk micro SD Ultra'. There was no doubt about this as it was also new product.
Following the advice you gave in the comments, I bought a new SD card and was able to install Rockbox and use it normally.
