Tutorial Simple Guide to Downgrading your 3DS

[WeedZ]

Browserhax. It's possible to obtain homemenuhax in 3DS 10.3?

Yes, the new starter pack from smealum's site has a homemenuhax installer to be run from any other entrypoint.

What entry point? I recommend homemenuhax and hbl 2.5

Youre more likely to get a brick

Why? have you try it?

Successfully downgraded my O3DS from 9.9U to 9.2U using menuhax as the entrypoint! Although I encountered black screens before successful bootup. Thanks for this guide!

Guys, Im stuck on 'Updates installed. Rebooting in 10 sec.'
Its literally frozen and its doing nothing. Should I take the risk and power off?

Help. Using Steveice10's latest version. Getting this error:

titleException:
main.cpp:108: Result: 0xD900182F
Failed to get CIA file info!

Extracted CIA files to "updates" folder with 7-Zip.

There have been alot of reports of bricks with n3ds. I'd say 60%, maybe more. There have been successful downgrades but it's up to you if you want to gamble with those odds.

Hello!
In recent days, there have been many developments within the 3DS homebrew community, with one of them being kernel access! With this, we now have a way to downgrade 3DSs and do whatever we want with kernel on >=9.3 3DSs. What's that? You want to downgrade? Well then, here's how...

PLEASE NOTE: JP N3DS Users, you'll need to remove the 000400102002CA00 title in order to not get bricked! Not sure if other regions need to do this as well.

ALSO NOTE: Note: So far NO ONE HAS BRICKED THEIR 3DS FROM THIS. HOWEVER, I AM STILL NOT RESPONSIBLE IF YOUR 3DS BRICKS. If it does, I'm sorry, but it is NOT my fault.

Before beginning, remove any DNSs (like Tubehax) that you may have on your 3DS. This can interfere with the downgrading process. You may also want to back up your SD card juuuust in case...

1. Grab the sysUpdater app from here and place it into the '3ds' folder of your SD card.
2. Make a folder called 'updates' on the root of your SD card.
3. Place all of the CIAs for the update you wish to downgrade to into the folder. (I cannot link these for legal purposes. Sorry!)
4. Eject your SD card, put it into your 3DS, and boot.
5. Open up the Homebrew Launcher in your entrypoint of choice and start the sysUpdater app.
6. If everything goes well, you should have some options. Since we're downgrading, you can go ahead and press the Y button.
7. Wait and DO NOT touch anything. The app will tell you when it is done. (It took me less than 5 minutes)
   
8. Once the app prompts you that it is done, wait. It will reboot automatically.
9. Bite your fingernails in suspense. If everything goes correct...
10. Your 3DS will be downgraded!

COMMON PROBLEMS:

Issue: The app freezes at a certain step!
Solution: Try a different entrypoint. I was using Ironhax and got this problem, so I switched to OoT3DHax and it worked.

Issue: The prompt comes on screen, but nothing happens when I press a button!
Solution: Either wait a few moments or reboot the system and try again.

Issue: I downgraded, but my 3DS screen is completely black upon reboot!
Solution: Try removing the SD card, or you can reboot into recovery mode. To do this, hold A+R+L+Up as your 3DS turns on.

(please recommend any other issues and solutions to add here please!)

Im frozen at there too.

It would be great if someone could makea very detailed YouTube video of how to perform the downgrade properly on an o3ds. I'm more of a visual learner although I can do or from the instructions I like videos just to be clear on every step.

[LooneyElsa]

New one, failed to verify CIA files first time - just restarted and retried.
also here the stick so it can be seen its a new 3ds & progress
I don't really know much about customization or anything, it's just the out of the box new 3ds and I did what was suggested in the OP with the new SysUpdater & menuhax

I was wondering if any of you people have a link to MD5 of 9.2 updates?
