    If someone has Chimera Tool it can do the same thing as SamKey for free

    Try to flash it with some other pack (South America is OWO not OXM so it should do the trick) Then flash it back with OXM, inster your simcard and see if it will ask you to reboot the phone to set the sim card settings.

    I know that Chimera Tool can change the csc, as I had to do that becuase I wasn't able to get SFR csc normal ways

    I think You are confusing knox with Flash Counter, FC can tell the samsung service if someone flashed the phone or not. And because of that they can reject the warranty

    I will repeat my question. Since SFR and XEF are in the same OXM pack, how do I get SFR csc?

    Sorry I meant OXJ not OJV, in previous models SFR was part of OXJ and on some models it was default csc after flashing and in some models you had to activate it with SFR sim card. For some reasons I need the csc on the phone to be SFR/SFR/SFR/EUX(The last one really doesn't matter). But I just...

    Xef/xef/xef/eux Normaly SFR was part of OJV so I just insterted SFR simcard in and it switched to SFR, but now SFR is part of OXM, and so is XEF, so when I insert SFR simcard in it sets XEF, not SFR.

    I am trying to get SFR firmware on my phone, right now it's BTU, when I flash it with G988BOXM1ATBM and insert SFR sim card it gets me XEF (Generic french) not SFR, it looks like all network brands are in the same OXM bundle as generic firmware.

    I would like to know as well. I know that AT+PRECONFG changes csc in combination but there is also AT + RFBYCODE = which I don't know what it does .

    Post Now you can not change CSC code with firmware + SIM-card

    It looks like originaly you had OXM (XSG is part of OXM, so at this point you could insert any simcard and it would get customized) firmware on your phone, and then u flashed it with TKD, the two middle csc are from inserted sim cards, so they will always change. I am afraid that if you flash...

    Specify what model you have If s10e (G970f) or s10+ (G975f) you can just flash it with OXM and use simcard to change csc if it's S10 (G973f) the only way is SamKey. Sometimes the s10 come with generick csc like DBT, ROM or ITV, then you can use simcard, but if it has BTU or any network branded...

    No it is not. I am debranding dozens of s10+ and s10e as we speak, and I am using just Odin and simcard for it. The only phones I have problem with are G973F And Note are not a problem neither

    I don't get why people keep paying for samkey for G970 and G975 while the problem is only with G973

    Some ADB commands changing partitions, or AT commands. At the beginning I was leaning more towards AT commands, but now I think they use ADB. Someone would need to get a port spy software to see what commands are being send to the phone while SamKey is changing the csc.

    You can't flash combination file on S10. Neither there is a way to send AT commands (atleast the ones that change csc) in normal mode.

    That's exactly what I was thinkin about. Maybe real term has this option? I will dig into it. I've been thinking today. If it was just a simple command it would work for all the phones, but there was a case when this tool wasn't supporting some of the phones. And I found an old topic where you...

    Has anyone wondered how samkey does that? I am 99% it sends some AT command, but so far I was only able to do that with combaintion filed flashed on the phone, and this tool somehow managed to send it to the normal firmware. Does some one have any idea how? I can see in the log that it sets up...

    CSC allows to use VoLte , pay services etc. There is a paid service SamKey which allows you to change csc to whatever you want. I tried to break it down, but it doesn't make any sense to me. So You can't flash combination so this tool doesn't use it for sure. So it must be sending some AT...

    Post Combination/Factory binary(SM-G973F) - New Odin Protection

    There is an exe. combination for G950F U5 (which uses same security as S10), maybe there is a way to make said exe file for s10 and other devices? I can share a link to the exe combination, but I am not sure if it's allowed, also it was made by one of the boxes.
