What I Believe Is The Best Downgrade Process Right Now

This is thanks to u/perkel

After Many tries and hours I found this users steps and followed them to success (n3ds). I got through the downgrade process and it automatically rebooted without any problems (no black screen or having to remove the sd).

Here's Perkels solution, and I quote:

"- formated my n3ds (had 10.1, updated to 10.3 then format)
- formated SD (32gb kingstone class10) with SD formater (format overwrite + formatsize adjustements)
- downloaded 9.2-20E firmware for N3DS
- checked md5 of above firmware via this site
MD5: 6dcca8fcbc9a28c82c2a4e5182f3acf8
SHA-1: e7c77bf205137167f1f1befa0c4db9d879a21a2e?
- downloaded this systemupdater which julian posted (SULib one) MIRROR

thread where given (if curious):
https://gbatemp.net/attachments/sysupdater-zip.34449/

- downloaded starter kit for homebrew (from smealum site)
- installed TeraCopy to ensure nothing will be damaged via copy/paste on SD card

- put SD to pc
- copy everything lower via teracopy program! (it will show your option when you do it just via copy/paste like normally you do after you install that program)
- copy starter kit folder content to sd card
- copy sysupdater to 3ds folder in your SD card
- copy updates folder to your SD card once you unpacked your downloaded and checked via md5 sum FW
- get your SD card to your 3DS and set up your 3DS (date, time etc.)
- change your theme to something else and back to default (to ensure menuhax will work)
- do browserhax (scan QR code [L+R and then that left sticker] from this site)
- you should go into HomeBrew thanks to above
- choose menuhax manager and install menuhax
- restart your 3DS and hold L to go into homebrewlauncher directly

Once above is done you have properly installed homebrew on 10.3 and it is confirmed that all files are 100% safe to use (that FW you downloaded) and nothing weird should go wrong (it still has that chance though)

Once above was done i started sysupdater from homebrewlauncher.
Since memchunx doesn't work most of the time i had to try 7-10 times before i got #8 success and sysupdater menu.

Then i pressed Y, nothing happened for 3-5 seconds
Then cheking CIA files... or whatever that was for 10-30 seconds
Then it started to install CIA files
Then it got to autorestart in 10 seconds
Autorestarted (NO CRASH)
Booted into 9.2 system without problem perfectly (without taking out SD card)

In other words perfectly updated without single crash (aside from getting into sysupdate menu)

I give my humble thanks to whoever worked on memchunks, julian for this fantastic build and ton of other people that showed me way to ensure everything will work correctly (like teracopy, md5 etc).

Now i have 9.2 and i am wondering what should i do :) Good thing to wonder about :)"

Happy Downgrading!

Follow guide to the tee.

Format card using same app

MicroSD card that was once readable not readable now.

Great.

Format it to fat32

Edit: looks like you got it:)

--------------------- MERGED ---------------------------

People don't seem to be answering any questions about the Failed to get CIA info error at all. What's up with that?

I had this error until I formatted my sd and console. I don't think anyone has a definite solution.

Can anyone confirm if the standard new 3DS that released here in the US a few months ago can go to 9.2?

If its possible I may buy it

The reason some people lose their games and saves is because they had menuhax installed beforehand and it's conflicting with the downgraded firmware. It's an easy fix, just insert the SD card after booting and change the theme.

Anyway, the best downgrade process right now is waiting a few days for it to get more stable.

This worked for me on Majora's Mask N3DS EU from 9.9.0-26E to 9.2E! I did not format the system (might do it later to unlink nands though), just the microSD using the built in Windows format tool, FAT 32, quick format. Moved all the files over normally, then Ejected it from the context menu. I used Cubic Ninja on Sky3DS to access *hax, then installed Menuhax. Took 5 tries to get the sysUpdate to reach the point where you can start the downgrade. When it finished, I had to force turn it off at the "Rebooting in 10 seconds" as nothing happened. I forced it off, took out SD card and booted and it works!

Thanks!

I had issues doing my n3ds and did basically everything except trying a new card and teracopy. I'm not sure what helped but following these directions, verbatim - including updating from 9.9 to current and then formatting worked. I used to always get stuck at steps 5-7 but after a couple reboots into HBL and sysupdater it got to 8 and worked the first time.

So, a huge thanks for helping make my N3ds a vastly improved tool!

OK I get that you can backup save data before formatting, but what happens to streetpass and extra data? It's the final thing I need to consider before downgrading.
