Did you check the state of this little switch? Maybe your SD card is just write protected.

But then you didn't follow the guide "correctly". Even though you shouldn't do that either way. First dump the Nand, then install Haxchi+CBHC. You can also see in the video.

I also try it before installing Coldboot Haxchi.

Just a little piece of advice... Next time avoid YT videos and use this guide instead:
