Alright faggots. Here's what you all came here for.

==HOW TO DOWNGRADE YOUR 3DS WITH CIAs==

'''What you need:'''
==A 3DS on version 9.3-10.3 with access to your Internet Browser==
Homebrew Launcher - Make sure your *hax is up to date - Get the current starterkit from smea's site
This version of SysUpdater: https://www.dropbox.com/s/r4o8q9hnxta75io/sysUpdater.zip?dl=0
Full CIA set for your system - 9.2.0 is your best option

Need CIAs? 3DS ISO is where you want to look, but here's the USA CIAs.
USA O3DS: https://mega.co.nz/#%21hBhBUbiQ%21-TfpWoCcCNEky-EfWHFDb1Cf6Ob0VJL0oF01J2YD2Cs
USA N3DS: https://mega.co.nz/#!kAZzQQRa!zLEQMInVl901gKcP8yttTRQhV0KqbWqst2VlXDJ6xH4

'''STEP 0.'''
Disable Tubehax DNS
>B-b-but what if I update
If you brick your shit, you won't be able to use safemode to recover because of tubehax blocking Nintendo's servers.
==10.4 is out, so if you softbrick your devide you won't be able to try again if you need to update to save your 3DS.==

'''STEP 1.'''
Copy the Starterkit to the SD card root
Put Sysupdater in the 3ds folder
Also, create a new folder, updates, in your SD card root.
Place your (extracted) update CIAs there.
==IF YOU HAVE A JAPANESE N3DS, DELETE 000400102002CA00==
If you don't, you WILL brick your system, and we cannot help you.

'''STEP 2.'''
Get to the Homebrew launcher somehow.
Now Install Menuhax with the most recent installer
>But I have Ironhax/already have menuhax
You need to be up to date for this to work, and menuhax works better for this, trust me. Not only is it faster, it's more reliable and more convenient.

'''STEP 3.'''
Power off your 3DS, turn it back on while holding L
Now open SysUpdater
>Did it work?
Probably not.
>Is it stuck at Step 5, 8, etc..
Reboot. Try running FtBrony and quitting out ASAP before opening sysUpdater, it somehow makes it more stable
>Do you see text after step 8?
READ IT.
==IF THE TEXT IS FUCKED IN ANY WAY, DO NOT CONTINUE: DO STEP 3 AGAIN==

'''STEP 4.'''
Double Check. Text looks normal?
Cool. Proceed.
Press Y. You might have to hold it for a bit.
It will take some time to make sure your CIA are there, native_firm is slow to patch. After that, you'll get to see it install CIAs
==ONCE IT HAS STARTED DO NOT RESTART FOR ANY REASON==

'''STEP 5.'''
It way say that it is rebooting your device once it's finished installing. Let it reboot and don't fucking touch anything.
You may have to remove your SD at first to get it to boot, but your mileage may vary.
If this happens, go to system settings, and uninstall Ironfall. Then change your theme.
Now would be a good time to block updates with tubehax DNS. If you never had it, the IP is 107.211.140.065
Use Browserhax to reinstall menuhax, too.

'''STEP 6.'''
Backup your NAND - I recommend Gateway Ultra 3.4 (it works, and I don't trust new versions to not brick my shit)
>Why do I want a NAND backup
If you really mess up your 3DS, you can always restore your 3DS to working order with a hardmod from here on out.
