I want to format my microSD card, but when I try an error says that the file system is read-only. I found this, but none of the answers work form my case, which is identical to the one I linked to. Any helpful suggestions?
It's possible your SD card may be corrupted. If it's not and you're using an SD adapter, there's a little switch that you have to toggle to disable write protection. If that doesn't work, 99% of the time, it mean your sd card is corrupted.
