Ubuntu 18.04 micro sd card locked readonly

I am running Ubuntu 18.04 on one desktop, and Windows 10 (19 something the latest version), on an old Dell Vostro-220 on another desktop. The mission is to flash an android OS onto a micro SD card for use in a Raspberry Pi 3B.

The SD card is a Samsung 32 Evo+ that has the Raspbian Stretch OS on it and the Pi works fine. I powered off the Pi and removed the Samsung SD card. I had the downloaded Android OS in a folder in my Dowloads directory. I plugged the card into an adapter (that has NO readolny switch), into the Ubuntu desktop. The card is found and the files are readable.

I am using Etcher to flash the OS onto the SD card. Etcher shows the card as “Locked”. The card is locked in a readonly state

I can not remove the folders, format, delete the partition, or write to the micro SD card. I tried:

  • gparted
  • disks
  • parted
  • guidus
  • dd commands
  • Changing permissions and ownership
  • disk manager in Windows
  • diskpart in windows
  • formatting in my Samsung Galaxy phone
  • maybe a few more “fixes” I can’t remember

Nothing has worked. I have created a ticket at Samsung but there is no one in customer service today, Saturday. Then I tried another used 32 gig mirco SD card that I had taken out of an old phone. I got the same result. I thought maybe because it was formatted in a phone that it was locked in readonly.

So I plugged in a brand new micro SD card. I opened Etcher to flash the Android OS to the brand new, never used, just out of the package, micro SD card, that has no switch, and got the same result. Etcher says the SD card is locked. It is in “readonly”. Nothing I have tried can make it writable. Three different cards, three different brands, 1 new, 2 used (but working fine before), I plugged them into the 18.04 desktop.

I have spent several hours searching for a solution, and tried many things. Has anyone actually solved this problem? Please advise.

Questions about Card Skimming Etc [duplicate]

This question already has an answer here:

  • Clone debit or credit card 1 answer

With the MagStripe and other technology being able to Read write and erase card info with a swipe. I am wondering if one is able to encode fished cc info to a blank card. For example

If someone stole my debit card number, name, exp date and cvv. Are they able to use that info on the swipes and put my debit card info on a blank? and use that blank for purchases in store ?

unable to mount a SD card sudo tee /sys/bus/pci/rescan

I want to access the SD card of my mobile. So I removed it from my mobile and connected it via SD card reader /USB with my kubuntu 18.04 PC.

$  sudo fdisk -l /dev/sdc1        32768 249737215 249704448 119,1G  7 HPFS/NTFS/exFAT 

If I try to mount it I cannot get the matching type:

$   sudo mount -t vfat /dev/sdc1 /media/anja/SD 

complain about wrong type. What my kernel offers are the following types:

$   cat /proc/filesystems | awk '{print $  NF}' | sed '/^$  /d' sysfs rootfs ramfs bdev proc cpuset cgroup cgroup2 tmpfs devtmpfs configfs debugfs tracefs securityfs sockfs dax bpf pipefs hugetlbfs devpts ext3 ext2 ext4 squashfs vfat ecryptfs fuseblk fuse fusectl pstore mqueue autofs rpc_pipefs nfs nfs4 

What can I do to access my SD card?

no connection with Broadcom BCM4311 802.11b/g WLAN wireless card

Since I installed Lubuntu 18.04.3 recently (on a Lenovo 3000 N-100 notebook) I have no wireless connection. I’ve read several previous AskUbuntu questions. Regarding the first answer to the AskUbuntu question at https://askubuntu.com/questions/55868/installing-broadcom-wireless-drivers, I believe I followed the section titled Installing The Package (Online). There is still no wireless connection. Here is a current screenshot of the system tool Software and Updates. enter image description here

If you can help with suggestions, please make them clear and complete, step-by-step, without unnecessary assumptions/jargon/etc as I’m relatively new to Linux, and my awareness of system architecture and software is quite limited. Thank you.
