    Hello all,
    I just upgraded the firmware from 6.1 to 8.1. Now when I try to run RAJNX CFW - PreventGCUpdate, it says
    Initializing...
    Unknown package1,
    Version <='20190531152432j_ sw20190531152432
    Failed to launch firmware.

    Can someone please let me know how to fix this error? I haven't updated anything since I set up ChoiDUjourNX quite some time ago.

    Hell
    Switch to stock atmosphere or kosmos, RajNX isn’t being developed anymore and doesn’t support anything past 6.2.0

    Yep - that worked. I had to change the payload as well to get it working. Thanks again ZachyCatGames

    Why did you downgrade to 8.0.0?

    The exfat version has the exfat FS driver, the normal version doesn’t. If you’re SD card is formatted as fat32 it doesn’t really matter which one you use, if it’s formatted as exfat you need the exfat version.

    Hello I have an I patched switch with fw 4.1.0 and I hacked it using hekate caffeine I'm using atmosphere on my emmumc or as I know emunand
    1. Do I need to update my emunand to 8.1 to play games for fw 8.1
    2. If I need to can I only update my emunand to 8.1 and keep sysnand on 4.1
    3.if I update my emunand to 8.1 through that codjonnx thing without burning fuses after I switch off and switch on will my sysnand be on 8.1
    3.if it does not after updating to 8.1 without burning fuses and turning off my switch and turning on will my fuses burn because I can't have auto rcm switched on because I'm using ipatched switch and I'll have to switch on sysnand and use fakenews injector to get to hekate through caffeine and open cfw atmosphere through hekate
    4.is there a way to open emunand on reboot like auto rcm on a ipatched switch ,if there's not a way to do that don't mind question 4

    1. yes
    2. this is a must with patched switch or else sol
    3. if you run choiDujourNX in your emummc it will only update emummc
    3b. bif you update with this app it won't burn fuses but since your on patched switch MAKE SURE your in your emummc
    4, No only the caffine way into hekate

    EDIT. you should read the WARNING Section on pega main page https://pegascape.sdsetup.com/

    @rajkosto can choidujountNX be updated to skip the gc reader firmware update to avoid it being lost if you're on lower fw than 9.0 later on?
    because it seems they are probably going to keep upping the firmware requirement for reader to prevent cart dumps

    thanks

    How do I find that im in emunand
    1.i can only open Homebrew in emunand so that means that im in emunand right
    2.i can only play games in switch after going to hekate and selecting payload and selecting emummc does that mean when I can open games and play that im in emummc
