    Hey guys, I'm new here, and I haven't found any thread about it, so.... here it goes:

    I have an O3ds, and just installed the a9lh using the gateway method. I`m not complaining, since I found it quite good, but I have a doubt.
    Is it possible to access the gateway menu or use the blue card with the gateway mode after the a9lh?

    Oh god. Did you install the Gateway Fast boot method? If you did, you're screwed. Your 3ds won't turn on without the Red card and the blue card won't work because GW's patches are terrible. If everything went OK you still have a nand backup without GW Fast boot (which is a really bad copy of the community a9lh by the way). Had you installed the community version and used luma (or cakes) you could've used this thread: https://gbatemp.net/threads/help-getting-gw-blue-card-on-luma-a9lh.442772/#post-6702688 and https://gbatemp.net/threads/gateway-blue-card-on-luma3ds-a9lh.439605/
    Okay what you need to do now is; locate the file otp.bin on your sd card. Restore the backup without GW Fast boot and then install the community a9lh. After that get luma3ds (CFW). There are some tutorials floating around on how to get rid of the gateway method.
    Once you're on the better fast boot method you can follow above links for your blue card to work. After that you can even get the red gateway card to work, without an Emunand. There is also a tutorial for this in the tutorial section.

    Thanks, Temarile!
    I guess that the GW method really was a bad choice, looking by what you've just said.
    And yes, I do have the backup files and the nand before a9lh.
    Guess I'll look around, to learn exactly how to remove the GW method without the risk of bricking my good O3ds.

    :)

    Hi, i want to uninstall GW A9LH fastboot, and already tried to downgrade in the GW Menu, but i get the message "Sorry, downgrading is not supported yet for your console." Ihave the pre fastboot NAND.BIN and the OTP.BIN.

    My console:
    Old 3DS XL
    sysNAND: 4.1.0-8U
    emuNAND: GW3D 9.2.0-20U
