Hi! My Nokia Lumia 520 changed file-permissions on my MicroSDHC to read-only filesystem somehow. After digging a lot of forums I found that this is typical Windowsoid, and even that I found for Linux is not helpful for me. I formatted SD on Lumia, but still have WPSystem folder, in which I got WPSettings.dat. Unable to cut them, and to paste something over there. Of course, using GParted I see "Unable to format, read-only filesystem". Thank ye!
