Homebrew [How-To] Downgrade your o3DS from 11.2

[Yepi69]

Since many people are having problems with this I'll clarify how I was able to downgrade my 11.2E o3DSXL.

1: Download the compiled safehax zip file provided by @zoogie and extract it to your /3ds/ folder.

2: Download Decrypt9

3: Extract the Decrypt9WIP.bin file to the root of your 3DS's SD Card and rename it to arm9.bin

4: Boot HBL through any entrypoint you see convenient (safehax would crash with soundhax, I used OoTHAX) and keep trying, safehax most likely won't boot Decrypt9 on its first run.

5: After that just continue from 3ds.guide



P.S: Once you get to the part of installing arm9loaderhax and booting Decrypt9, on 3ds.guide it says to go to ''SysNAND Backup/Restore'' and select SysNAND restore to restore your NANDmin.bin, such option is not correct, what you WANNA select is ''SysNAND Restore (keep a9lh).

Huge huge thanks to @zoogie and Ned Williamson.

If I made a mistake somewhere, please correct me
Also keep in mind that the code you're about to execute (fasthax + safehax) is entirely in alpha, hearts may break.
Be careful.

Works Perfekt whit Freakyhax.

Would this work on a n3ds?

 

[xtheman]

Would this work on a n3ds?

for o3ds

If I had a guess: no

 

[Yepi69]

Would this work on a n3ds?

There's already a working version for the n3ds, as for the o3DS there wasn't.

So I assume that this will also work on a n3DS but no harm in trying.

Can you link me the n3ds method

 

[Yepi69]

Can you link me the n3ds method

Its the same, the 3ds.guide link on my first post shows steps for both the o3DS and n3DS.

From the website?

From the website?

Yup.
Or do I need a torrentdownloader for that?
This just came in my mind...

I'll give it a try tommorow.

You do yes, it is mentioned in the guide.

So kids, don't try to follow clear instructions when you're tired

so when you download decrypt9, you extract it since its a .zip file and take the decrypt9wip.bin and put it on the root of the sd card and rename it to arm9.bin?

 

[cribaby23]

ok i got it to go into decrypt9 and now im putting the ctr files onto my sd card but i cant find the /files9/ folder on my sd card, help!

Just create the folder

Well, I used safehax with soundhax and slowhax on a eur o3ds 11.0.0.33, and that (with a gamecard inserted, did that without knowing that it helpt prevent freezes) worked Just fine. What is the big change in slowhax VS fasthax wich would make safehax and fasthax incompatable?

 

[Jarmarcus]

I installed Luma and Arm9, and now it says to update device. Everytime i power on the system, it say "failed to mount CTRNAND" any solution?

 

[Tomy Sakazaki]

...safehax would crash with soundhax, I used OoTHAX...

Inserting any cart on Slot1 will make Safehax launch Decrypt9 instead of stucking in the black screen. It helped me since I didn't had any other valid entrypoint on the japanese o3DS 11.0 and 11.1 that I've messed with yesterday (since I didn't know if steel sub was available in jpn eShop I didn't wanted to update the consoles).

 

[c4s1]

Yay, I managed to downgrade and set up a9lh+Luma.
Is it save to change the SD Cart and just copy over the data from one to another?
