    You'll need to follow the OTP retrieval part of this guide.
    After you got your OTP, you can update to 9.2 with a gamecard and install CFW.

    I'm sure there's people who are more knowledgeable then me who can help you more then I can.
    But by all means, DO NOT UPDATE BEFORE YOU HAVE OBTAINED YOUR OTP!
    You're on 2.1 which is the last FW which can retrieve said OTP file.

    That's like the perfect FW version! Even has a browser! I'd recommend dumping the OTP first.

    No, you don't need any. Just be sure not to update.

    The problem is, the separate OTP dumping payload got removed.

    You don't understand what he told you because he linked you to the wrong part of the guide. He was supposed to have linked you to this: https://github.com/Plailect/Guide/wiki/9.2.0-Update-(Browser-OTP)

    That page is linked from here and is specifically for people who start with 2.1.0-4.

    Anyway the story is that the best method of hacking your system and getting CFW requires downgrading your system to 2.1.0-4. If by luck your system starts on 2.1.0-4 already, you don't need to do that, and a few other steps change a bit. So there is a special simpler set of instructions if you started with that firmware.

    I believe the FBI instructions are slightly wrong for 2.1.0-4. You use SysNAND options when injecting the FBI.

    (Incidentally, 2.1.0-4 was the current firmware for the most time compared to any other firmware. According to Nintendo's list, it was available from June 15 2011 through November 12 2011, which is almost five months. This is probably why people keep turning up with 2.1.0-4.)

    Follow the link jiro2 just posted and do everything it tells you to.
    Just don't skip anything and read everything carefully and you will have a CFW 3DS with the possibility to just play all the games you want and more.
    Good luck and ask if you have a problem.
    For livesupport just go to the irc and ask there.

    Make sure your card is FAT32, then follow the guide. You'll have the prefect CFW setup.

    That file is very important. Make some copies of it and put it one usb drives and multiple clounds so you never lose it

    Now go on this page and look at the options possible for your System Version(the table at the bottom, second row, middle cast for you): https://github.com/Plailect/Guide/wiki/9.2.0-Update
    Since you are on 2.1 you will need to update to 4.0 or 6.0(with a game cart) first and then you can use rxtools to update to 9.2.
    After that just follow the steps below:
    • Do Part 1 - Homebrew
    • Do Part 4 - 2.1.0 Downgrade (Section II - Injecting FBI Only)
    • Do Part 5 - arm9loaderhax
      • Copy SafeA9LHInstaller's 3ds folder and dat file instead of the arm9 and arm11 bin files
      • Copy otp.bin to /a9lh/
      • Launch SafeA9LHInstaller from Homebrew menu instead of browser
      • Skip steps related to "emergency files"
      • Skip steps related to "RedNAND"
      • Skip Section IV and Section V
      • Update to the latest system version after completing Section VI
    The points under Do Part 5 - arm9loaderhax are modifications of the steps in Part 5, additional steps or steps you can skip.

    If you still can't figure out how to continue, just give me ur skype via pm and I will help you out.
