Yes, Richard Burton's evoplus_cid was the "Linux terminal solution" which I used years ago. I had some trouble compiling binary on newer Linux distributions but luckily Ubuntu 14.04.6 LTS is still available and evoplus_cid can be compiled on that release. Also, that same "old" Ubuntu had some issue booting on my new Lenovo laptop but I had old Acer from 2018 available on which it booted fine. Afterwards its pretty straightforward:

Code: Select all

root@ubuntu: apt-get install git gcc
root@ubuntu: git clone https://github.com/raburton/evoplus_cid.git
root@ubuntu: cd evoplus_cid\jnl
root@ubuntu: gcc evoplus_cid.c -o evoplus_cid
root@ubuntu: lsblk <-- to find out which is memory card identifier (mine was mmcblk0)
root@ubuntu: find /sys -name cid -print <-- you should get device address
root@ubuntu: more address from previous command (something like /sys/devices/pci0000:00/0000:00:*****/cid)
this is your current CID (write it down)
root@ubuntu: ./evoplus_cid /dev/mmcblk0 0941504146205344021a5a7753018801

After you get message that CID was successfully written, reinsert SD card and with previous command check the new CID

root@ubuntu: more /sys/devices/pci0000:00/0000:00:*****/cid

I have lost the guide when I decommissioned old PC so I was wondering if there is some up to date guide, preferably on Windows but I would manage linux as well.

Seems this tool should work: [Please Register or Login to download file]
It's in the 'libs' folder. Note that as usual, after downloading and before running the tool, you have to make the binary executable: `chmod +x evoplus_cid`
