Surely there have been many people who have wondered how to uninstall unlaunch, I followed this guide: https://dsiguide.me/downgrading_(TempNand) using the downgrade to uninstall unlaunch.
At the beginning I wanted to downgrade but uninstalling unlaunch was always in my plans and then after I downgraded, unlaunch is gone.
I thank LukeHasAWii for the guide.
I DO NOT TAKE RESPONSIBILITY FOR BRICKS because then the guide is not mine either.
Tip: I recommend using ugopwn in the zip file for non-US consoles.
Tip 2: If the page of the site has been deleted or the site has been closed I suggest using the Html file in the zip file (ZIP:/Site(only if the site does not work)/Downgrading (ugopwn) - DSi Guide.html
Tip 3: If you have unlaunch with firmware 1.4 I recommend upgrading to 1.4.5 (Never tried because I do not have a DSi to brick) and then follow the guide.

If it’s unlaunch and you’re uninstalling it, wouldn’t it be launch?

 

[DSUPERY92]

my DSi starts without problems.

Technically, you could follow the guide but for "downgrading" to your current firmware, removing unlaunch but keeping the same firmware.

 

[DSUPERY92]

I can not test it because I do not have DSi / DSi Xl to die, and I'm not good at welding.

 

[Oleboy555]

why would you uninstall it though?

Relaunch?

 

[SirNapkin1334]

Relaunch?

Well, it’s a double negative.

For those who want to sell the DSi / DSi XL.

For those who want to sell the DSi / DSi XL.

I thought you make a NAND backup before installing it

 

[DSUPERY92]

The guide that I followed, however, can be useful for those who have no backup before installing unlaunch or who lost for what reason in the world(me)

Hacked systems go for more.

Hacked systems go for more.

Some refuse to take hacked systems.

 

[DSUPERY92]

I am of the opinion that if I want to install something I am free to uninstall it or not and I wanted to give this freedom to those who want to uninstall unlaunch.

Can you edit save files or .pk for gen 1-3 with it, or at least add them to gen 4?

cheaper sometimes more, right now 3ds with homebrew and CFW are 20 bucks about 5 with shipping, others are trying to get $150. Right no ebay 28 bucks. Just looked only cause I didn't have Homebrew or custom firmaware on my systems (except one thats stolen) so I was looking for one because basehax works with 11.7 apparently.

Is it just me or does the site no loner work?
