So I just downgraded my brothers 10.3U O3DS to 9.2U using SafeSysUpdater using Menu Hax (His was the very first one I've ever downgraded)! Here were my steps because I know people always ask what others did, and I like being helpful:
I first reformatted the 3DS so that is was all factory settings (I did not reformat the SD Card).
I then installed Menu Hax via Ninjhax. (I used Type1 setting for it to run because I rather hold a button to start HBL)
I then downloaded the 9.2U FULL Update CIA Pack from that iso site.
I then moved SafeSysUpdater.3dsx into /3ds/SafeSysUpdater/ (I had to create the folder since it wasn't in there)
I then copied the 9.2U Full Update CIA Pack into a folder called "updates" on the root of my SD card.
I then inserted the SD card into the 3DS and started Menu Hax and started SafeSysUpdater.
I had my WiFi turned on and pressed "A" to verify the MD5's of each of the files (All were Good to go!)
Once that was done, I finally pressed "Y" to downgrade the 3DS.
I made sure my 3DS was plugged in and I didn't press anything while the process was taking place.
The downgraded finished and it didn't restart in ten seconds like it says, but it does say if it doesn't to just PowerOff if it takes longer than then seconds, so I did.
And viola! I went into System Settings and I was a Firmware 9.2.0-20U!
I haven't checked to see if Browserhax works, (or anything else for that matter) but it does turn on, which is a huge plus.
I'll be buying my brother a bigger SD Card so that he can then do whatever he wants to with his 3DS!
EDIT:
So I managed to try some different hax and Ninjhax works perfectly but browserhax does not. Everytime I try to run browserhax it gives me an error and force closes the browser. Could it of not downgraded with the rest of the files?
I did run the downgrade checker 3dsx and this is the output (I ran it twice so there might be double the amount of titles):
