    Final Update: This was an issue with the RSA checks and keys. This was NoCash's comment:
    "Unlaunch does disable RSA checks. Without Unlaunch you will need to have the RSA keys, else you'll get the "Error: 2-2435-8325" message upon boot. You'll need the DSi BIOS roms in the No$GBA folder."
    It's confirmed that Unlaunch will be uninstalled successfully on a DSi.
    Sorry for the inconvenience.



    (Outdated)
    So it was yesterday when for fun, I hooked up my NAND dump to No$GBA 2.9a and I had some fun with it. As a test (and because there's no sound in the menu), I wanted to take a look at what happens if you delete Unlaunch. I thought it would just recover the regular menu, but no.

    Instead, it fully bricked with all the SDNAND patches deleted.
    Error (DSiBrick).

    This is a screenshot of what you see. Discord user @edo9300 did some research and it said it means "invalid firmware". He told me to compare the fixed NAND with the bricked NAND. It took me a while, but this is where the issue lies:

    NAND:\title\00030017\484e4150\content\title.tmd
    differ.

    484e4150
    is the System Menu (for Europe) and a *.tmd is required for the firmware. Not only is this a warning to everyone who hasn't done this yet, but also a bug report to No-Cash which a patch has to come out soon for.

    In short: Do not use the uninstall feature, all what can bring it back is a hardmod.

    No problem, by the way, I already issued this "bug" by the man himself, so no more emails need to be sent, or else it will looks like a spambot.

    It looks like there is an extra line of code remaining, that is trying to be loaded but essentially fails to do so

    I mean if you're a better programmer/hacker than nocash feel free to release your own coldboot DSi exploit, and if you're not you don't need to attack them when something doesn't work :)

    I didn't attack nocash at all, I was just sarcastically thanking him for something with issues, I appreciate the work he does but when there's things that don't work then they don't work, can't ignore it but I'm not going to seriously praise it either (that'd just be kinda dumb lol)

    So it would uninstall successfully on a Physical DSi?
    I want to know so i don't accidentally brick my DSi.

    The brick risk is the same as when installing it, as for now nobody ever bricked on a physical console

    I've recorded it from my emulator, but again, No$GBA forgets to add back the RSA keys.
    I think this wont happen on a regular DSi.

    Why are you saying such a thing? You didn't have had the bios file with the rsa keys before installing unlaunch, no$gba can't possibly "add back" those keys if you did never had them.
    Your setup didn't work before installing unlaunch, and that's why it can't possiby work after uninstalling unlaunch.

    Also - you seem to have edited the first post in this thread - but it would have been nice if you would have mentioned that in a later post. There appear to be lots of people not being aware of that edit. Half of that people are now on a mission telling around that uninstalling doesn't work. The other half is telling around that they are utterly surprised about uninstalling having worked for them without problems.
