situation as follows: raspberry pi broke in half (no comment), now trying to fsck or reformat the card and it's read-only:
fdisk: cannot open /dev/mmcblk0: Read-only file system
device notifier shows three partitions, /root, /boot, and /SETTINGS
trying to check /boot partition on the card - the only one I can mount, gives that:
open: Read-only file system
What to do?
