[Question] Downgraded my 3DS from 10.3 to 9.2, but now it is acting strange

To downgrade, I used this guide: http://wololo.net/2016/01/04/3ds-system-software-downgrade-tutorial/
Then I attempted to use this guide to install rxTools: https://gbatemp.net/threads/tutorial-installing-rxtools-custom-firmware-3ds-and-2ds.390867/

However, when I attempted to launch homebrew through Ironhax, Ironfall stays on the 3DS loading screen (with the red 90 degree angles) forever when trying to launch. Thankfully, I can just use Menuhax2.1, right? Wrong. Every time I attempt to load it up, it just goes to the home menu screen like normal. Among other screwy things, the Internet Browser method fails and I can't load up Super Smash Bros for 3DS on my SD card without receiving an eternal black screen. How can I fix this? I wouldn't mind losing homebrew at this point if it means I can have a functional 3DS with all my saves and purchases, but I ideally I want to be able to launch rxTools.

 

O3DS.

 

I tried to, but I didn't know how to use SafeSysUpdater, so I just used the original. How screwed am I?

 

Yeah, Super Mario 3D Land and my R4iDS card loaded fine. I'll look into that then.

And lol, this gives me a good incentive to actually play Shovel Knight.

Well it says it does here...

What exactly do you mean by "delete the update"? Should I try to install another entrypoint, upgrade to 10.3, and then try to downgrade again?

 

I just get a white screen with a slider on it. I tried it twice by scanning this QR code. http://yls8.mtheall.com/3dsbrowserhax.php

Err, how exactly do I go about doing that? Wouldn't my 3DS update if I go to the eShop?

 

Actually, it's an epic fail on my part. I forgot to actually download browserhax onto my SD! xP

In any case, I tried that, and I just get "An error has occurred. Please save your data in any software currently in uses, and then restart the system." Just like when I tried to install rxTools.

EDIT: I'll try to do the left side after I delete Smash.

EDIT 2: Err, do I delete the downloadable content for Smash or the extra data?

EDIT 3: Yeah, I got an error when clicking the left part of the slider too...

 

Browserhax works! I'm now in the homebrew launcher!

OK, now that it works, what should I do next to prevent my 3DS to becoming further fucked up? Should I go ahead and download rxTools? Or launch menuhax manager? I really don't want to screw this up, lol.
