    If you want to try writing CID register to a card other than Samsung, using evoplus_cid program, you have to compile it yourself to run with Linux anyway,
    so open evoplus_cid.c file and comment the call to the cid_backdoor() function, so the program wonít exit without trying to send CID register data like this:

    many Alibaba sellers mislead in their product description, because they want to attract buyers. They advertise their products as CID changeable SD cards, but reality is that these SD cards have fixed CID (by buyer's request) and CID cannot be changed later. I will be surprised if there is a seller who is selling CID changeable sd cards along with software for changing CID, because that would be (I believe that is the reason) bad idea for his long term busines. Or maybe not, I don't know..

    Maybe you are wrong. This is why I rewrite mmc (64bit and 32bit look at my posts) to find those cards. No return info as you see, no list of working sd cards.
    Chinese card have fixed CID (as janch has told you).

    BTW: All of those card which you can change CID with CMD26 (there are some of them mostly old ones) doesn't meet SD Association standards.
    But you can try my mmc with this two parameter:
    mmc cmd26 <new_cid> <device> (SPI)
    mmc writecid <new_cid> <device> (non SPI)


    So try you have nothing to lose.


    If someone find some working cards please, please, please tell us!

    @Vorlon, Iím only speculating here. Iíve used nothing other than Samsung cards myself.
    The older MMC cards I wouldnít be interested in myself. They arenít of use to me unless they can contain more data than an original map card can.

    I only suggested a way to make evoplus_cid send CMD26, even if the card isnít Samsung.
