    Can you check the speed of both cards? Because it seems to me that the newer ones are already faster, and the older ones a bit slower 80 MB / s are without blockade - after that, perhaps you will be able to recognize the blocked or unblocked version without unpacking the card and without reading the CID. It would be an important clue.


    The cards were the same as in your picture above.

    MB-MC16DA / EU - success !, saves CID, but after removing and inserting - shows original old
    CID 1b534d303030303010eae153ad010800
    and so it shows that it saved ok:
    Writing new CID: 5d5342303030384712750a9e2f0117bf
    Success! Remove and reinsert SD card to check new CID.
    or with another "Russian" instruction like this:
    Writing new CID.
    ioctl: Connection timed out


    both Made In Philipines

    Someone has any suggestions, conclusions, or maybe I'm doing something wrong, because the "second" DA / EU should

    Maybe someone is to sell "good" with a changeable CID?
    or some link to an auction, a seller who has "certainty"?


    You have a card from 2016.08 so it should go as I think.

    Does the reader not have to be integrated on the pci for this to work? I don't think a usb reader (sometimes there are built-in ones) will allow you to make raw entries.

    In the past, for programming the memory in the Xbox, you needed a reader that was seen as mmcblk and I found that too. Exactly the same device code in Linux was as the integrated ones.
    I would have to dig it out of the dark corners of the scraps, but in my opinion, this should also allow CID to be changed, if someone does not have a laptop with a suitable reader.

    Yes, the reader must be on the pcb of the computer, not usb, I also worked on it. Apart from having a USB reader, it would not read the card's CID number. He can read the CID, but he does not want to change.

    In one thread it was mentioned that on different Linux distributions the syntax of the commands is slightly different - maybe here's the problem. One of the forum members detected an error in one command and provided the correct command syntax. In my free time I will try to find this fragment and pass it here.

    Hi to all. I do everything as per the instructions. Reads old CID, writes to new card, writes Succes! but after checking it remains the same. The card is rather good, 80/20 evo plus 32, made in Philippines. Reader integrated in Lapku, Linux Kali live.
    What can I be doing wrong? The only thing that comes to mind is the wrong year of production

    As I write to you that he changed the CID number and in fact he did not change everything, you are doing right only your card has already blocked the possibility of changing this number. This was also the case with the first card from 2017, I only got the second card, the same only from 2016, and it all went without a problem. What is the CID number of this Samsung card because it contains the card's year and month?

    Can someone who managed to change CID to EVO write what Linux distribution he used? First of all, how does it boot - from USB, LiveCD or installer?
    After the adventures with the GA model and the Success! Remove and reinsert SD card to check new CID and of course without saving the new CID I managed to buy the previous Evo - DA model from 02.2016 and exactly the same effect. Theoretically ok, the card reads from / dev / mmcblk0, but after "more" I get in / sys / devices somewhere USB2. I run Linux from a bootable USB from Ubuntu, on a Dell with a card reader, which I do not know if it is plugged into a USB on a disc or in a pci. I am starting to wonder if this is not a problem with booting linux with a pen or a reader, so I will be grateful for the info, how did you run linux and on what hardware?

    Hello, I bought a production card from the Philippines, model MB-MC32DA / EU with the production date 10/2016 and I get the message "Samsung Evo Plus Genuine?" non-USB on-board reader. Could this work on a root phone? I'd rather not root my phone. But if it is to help, I will

    From what I found on the net, e.g. my card, despite the "good" date of production, cannot be readied - you can check it using the information provided by one of the authors of the method: [url=]http://maestroni.altervista.org/blog/problemi-schede-samsung-evo-32-gb/[/url] .

    Thanks for the link, however, I did root on the phone and my card is from 10.2016, it cannot be changed with the CID. So 65 zl in the back I am still wondering about cards from China. It is known that they will not have as much memory as they write, but always castum cid only if the method on evo cards will work on them? and you can easily change

    Hello. I bought a samsung evo + 16GB card from 2016. Mb-mc16da. I change the cid number and then I write success. Remove and reinsert the card. I do this and check the cid. The old one remains.

    Despite the older version of the card, it must be produced in Korea, like for my grandfather_1

    Why is everyone looking for Samsung cards? I bought a v9 map from a visitor on a goodram card.
    I would like to install V10 but I have a problem with changing CiD to Ubuntu.
    I guess I have some problem with the reader, can't find this mmcblk0

    Welcome.
    I have been struggling with reading and writing CID for quite some time.
    On one laptop, I was able to read the CID of the card with the ReadCID.exe program

    What program under Windows 8/10 32 bit do you write CID?

    On Linux, unfortunately, no laptop can read CID and the laptop running ReadCid does not start with Linux (freezes).

    Colleagues, does it have to be a Samsung card or it can be some other one, because I would like to test myself. I have some GoodRam, sanDisk, Adata cards.

    I also fell here, sometimes the laptop reads the card like an external drive (pendrive) and then you can't help but look for another laptop with a built-in reader

    I have a built-in reader. The laptop is Lenovo x201. I am sure it is not mounted as mmcblk and I do not know if it is a necessary condition? because with this the errors show up. How did you have the card formatted?

    I'm not an expert, but I think I must, I also have Lenovo y50-70 and not mclbk, I have to try on Samsung, but I do not have Linux there, nice as someone who managed to change the CID said

    I run Linux from a virtual machine or from a pendrive, but I do not install, I choose the options try, but in these two cases the same. I do not know if I will not try yet as described from the android level, but I do not know where to download everything to the phone.

    Added after 14 [hours] 32 [minutes]:

    Unfortunately, I fell on Androd, as if the card is visible as mmcblk1 but in linux I am thin and I cannot run the evoplus_cid command crashes the message that the folder is missing or something.

    Ok, I managed to find a paw, which the card loads as / dev / mmcblk0 but I have a problem with the CID change, can it mean that the card is not Samsung? After giving the command in linux to change the CID, something pops up, maybe someone will speak
    ./evoplus_cid / dev / mmcblk0 "MY CID"
    Failed to enter vendor mode. Genuine Samsung Evo Plus?

    Dell Latitiude 5480.
    Success appears on another card, but after checking the CID does not change, it remains the same. I suspect that the card is not suitable, you will have to look for a Samsung Evo, maybe at the brothers from the land of rice.

    You are probably right the card has no option to change the CiD. What is this card and from what production period?

    All the cards I have are old. I have SanDisk, Adata, GoodRam, and Samsung.
    It seems to me that the two went with Success, but the old no.

Report a violation of the law

Topic summary

The discussion revolves around the challenges of changing the CID (Card Identification Number) on Samsung Evo Plus SD cards using Linux. Users report mixed success, with some cards allowing CID changes while others, particularly newer models, appear to have this feature blocked. Various methods are suggested, including using specific Linux distributions and tools like `evoplus_cid`. Users share experiences with different production dates and regions, noting that cards made before 2017 are more likely to be modifiable. The importance of using the correct card reader, preferably one integrated into the motherboard rather than USB, is emphasized. Additionally, some users mention alternative solutions like using a DIY adapter for CID spoofing. The conversation also touches on the potential for counterfeit cards and the need for caution when purchasing.
