I have two micro SD cards I had inserted into a Navman MiVue 4K Pro dash cam. After formatting in the 4K Pro the cards failed. This made no sense since the cards worked well in other devices. I purchased new cards of the brand and type recommended by Navam. However, when I tried to reformat the cards, I got the message SDXC card is write protected.
After some searching on the internet, I found the following article. Method 3 in the article worked for me and I was able to reformat the micro SD cards. As this article was useful for me, I thought I'd share it in case it helps others in a similar situation.
