Hacking Downgrade o3DS 11.2E with Sudoku DSiWare?

[Yepi69]

So, I have a friend's o3DS with 11.2E firmware, I was using OoTHAX but now that soundhax came out I'm using that one instead, both work fine and I get into the homebrew launcher just fine.
Now, I wanna downgrade this system, however I know I need one of those DSiWare exploitable games but Ninty has removed them from eShop here in Europe as well so I'm out of luck I think.

I read that Sudoku's DSiWare version (the one from EA) also works and I saw countless guides and videos about it, however I just wanted to be sure.
Did anyone try to downgrade their system with a copy of Sudoku? I don't wanna proceed to an unknown area without being sure I'm doing everything right.
Yes I know Fasthax is coming out soon.

Sudoku on Eshop already fixed the expliot so it can't be use unless you find a way to replace it with an old version.
Which slowhax can't do it, also your 11.2 already fix that exploit.
Since you're on 11.2, only way you can do downgrade is here: https://3ds.guide/dsiware-downgrade-(save-injection-and-second-3ds)

I don't have another system or any access to any of those DSiWare downgrade games because Ninty pulled them off eShop.
Am I SOL?

Well, you have hardmoding as another choice. Or find someone who willing to do DSiWare downgrade with transfer with you.
