    I would like to swap the nands on my n3DS, but it seems that I need to remove the ARM9 Loader Hax I have installed. But I can not manage to launch D9 or GW ron restore the NAND backup. Any help?

    I never had to restore my Nand to switch emu and sysnand around.

    You say that you cannot run Decrypt9. I would assume that's because you're running on 9.6-10.4 FIRM, but you need to be on 9.0-9.2 FIRM for Decrypt9 to work. As long as you have 9.2 emuNAND or sysNAND to boot into, AuReiNAND will be able to boot with 9.0-9.2 FIRM. The instructions are in the release.

    You need to update your arm9loaderhax with dark-samus' installer.bin (rename it to arm9loaderhax.bin). This will enable screen init. Then you can use Shadow's decrypt9WIP a9lh port and restore your sysnand.bin. Search for the files in the a9lh discussion page

    I did not see that, I'll have to look.

    I attempted to downgrade my emu to 9.2 and my sys is on 9.0, but the only firms I can get to work kick me out of D9 and into the launcher.

    Thanks for providing links. :-/

    • Use SysUpdater on EmuNAND to downgrade it to 9.2
    • Run SysNand with 9.0 FIRM (hold L on boot, needs latest AuRei)
    • Open Decrypt9, backup all partitions of both NANDs that aren't FIRM
    • Inject SysNand partitions into EmuNAND
    • (Optional) Reboot now to make sure it worked, since all you changed so far is EmuNAND
    • Inject EmuNAND partitions into SysNand
    • Eject SD or shut down and add updatedsysnand flag to rei folder on SD
    • (Re)Boot, update SysNand, and you're done
    be sure to make a backup of both emu and sysnand ;)

    Never removed my a9lh

    Instead of all that downgrading emunand

    I backed up both sysNAND and emuNAND (full backups) then used D9 to backup each partition of emuNAND, excluding firm0/firm1 (as that's where a9lh resides)

    Cloned sysNAND to emuNAND then injected the emuNAND partitions to sysNAND.

    By swapping nands, do you mean swapping sysnand and emunand? I don't think you need to remove a9lh to do that. I didn't when I swapped my sys and emunands at least.

    My problem was not being able to start D9, but my stuff might have been out of date. :-/

    Strange it should work just fine as Logan's your holding the correct button on boot to load 9.0 firm

    FIRM is not always updated with every system version. When devs talk about loading a firmware image they refer to the version that particular FIRM was provided with, not the system version the NAND is on. Thus holding L loads 9.0 FIRM because 9.2 uses the same 9.0 FIRM, like 10.3 uses the 10.2 FIRM and 10.6 uses 10.4's FIRM.
