Use DD on Linux?you will have to restore using linux running on switch then
Can I refer to this tutorial?sudo blockdev --setrw /dev/mmcblk1boot0
sudo dd if=BOOT0.bin of=/dev/mmcblk1boot0 oflag=direct bs=4096 count=384

Your profile picture fits this situation perfectly.sudo blockdev --setrw /dev/mmcblk1boot0
sudo dd if=BOOT0.bin of=/dev/mmcblk1boot0 oflag=direct bs=4096 count=384
