    Hi.
    I have a bunch of working Japanese DSi consoles. They looks great in my collection and I want to keep it.
    I wonder if is there a chance to change language and region? By downgrading it or something? (is is possible to downgrade Japanese console?)
    I almost can't use the console apart of just gaming. :(

    Thanks,
    Marcin

    Using a hardmod or twlnf, try to copy shared1\TWLCFG0.dat & TWLCFG1.dat from an English DSi. DO NOT copy any other file or it will hardbrick.

    Search for "DSi SD/MMC Firmware System Settings Data Files" of http://problemkaputt.de/gbatek.htm to see how I found that

    No, It was just an idea, I haven't tried it. If you have a hardmod there is nothing to lose

    Thank you very much, @parrotgeek1. I'll try that solution and write about the results here.

    Have a nice day,

    I somehow found a dsi nand online that is not J (sadly versions dont match, its 1.4.5U, my dsi is 1.4J), but here are my reuslts:
    the name and color got changed
    every icon (like flipnote or dsi shop or pictochat) got english
    the language is still japanese.
    PICTOCHAT AND DOWNLOAD PLAY GOT ENGLISH, maybe games will boot now in english(?)

    im trying stuff with replaceing some files even if i dont know what im doing.
    i just want a german system ui xD (i know that i dont have a E Nand, but im searching).

    (and sorry if its a necrobump but i dont think it is one)

    can you PM me your NAND (with NO$GBA footer added!) so I can look at it? I think what's happening is that the launcher is still the J region

    With SD redirection its easier.
    (should i create a nand backup with the edited files?)

    No. I'll think about how to install USA launcher.

    Ok i found something. The region code is saved in the HWINFO_S.dat, its RSA-encrypted. So we need the RSA key from Nintendo or we do something different like injecting the language in the J region.

    No, we need HiyaCFW to add an RSA patch for that too. @Robz8
