    sdcard is completely and utterly locked...I've tried all I can think of

    Have an SDcard running Manjaro-ARM, and after doing a distro update it nuked itself and won't boot. Happy to wipe it and start over, but can't even do that.

    Things I've tried

    1. shred command
    2. dd if=/dev/zero (with and without bs=446 to wipe the MBR)
    3. using disks util in gui
    4. usb startup creator (GTK)
    5. e2fsck -y /dev/sda
    6. Tried to wipe with my android phone
    7. Tried gparted

    No errors in any of the above except #5, says it can't set superblock (tried e2fsck -b 8193 and 32768) . Everything seems to take, but everything is still there; partitions, files and all...even sda2 and sda3 are still mountable and readable.

    I also tried rewriting permissions on /dev/sda and /dev/sda3 (main partition with the OS and data)

    Drive layout:

    /dev/sda1 - unknown
    /dev/sda2 - U-Boot partition
    /dev/sda3 - Main partition with OS

    Any help would be greatly appreciated. A 256GB card is cheap these days, but I'm trying to get this back up and running ASAP.
