    I have a 2ds(a9lh).
    It has 11.0 sysnand. Is that possible to downgrade this 10.2 firm launched sysnand?
    I knew luma has the firm protection, but I don't know what will happen if sysupdater try to write the 9.0 firm to the nand

    I can restore a clean pre-a9lh-ed 9.2 nand, but I would like to keep all the data.:P

    i think if you are on cfw you can downgrade the firm installing the cia but that is something i cannot confirm

    What would you gain by downgrading to 9.2?

    Simple. Install the plaisysupdater cia onto your home menu and run it. Alternatively, if you are on Luma or on a cfw with a native firm below 11, run it from the homebrew launcher.

    That doesn't answer my question. Why would you want it on 9.2, even if it is your "idle console"?

    Just for safe keeping, in case the other one bricks, I assume. (It is very possible to cause an unrecoverable hard brick on an a9lh)

    Just make sure you are on Luma v5.5, anti-downgrade checks were patched.

    Thank @Densetsu I thought this was going to be one of those noob threads.

    That seems in very poor taste.

    What are you even talking about? The guy passed away... Why hijack this thread and try to derail it? Are you alright?
