Aftet getting repetitive soft bricks on my
OLD 3DSXl (yes old, i was unlucky), i finally formatted and the first time after making sysupdater work it downgraded properly with no problems.
Of course this was before 10.4 came out. If anyone is scared with the one shot they have:
FORMAT SYSTEM, FORMAT SD CARD, DOUBLE CHECK YOUR DOWNGRADE CIA FILES...
and you should be in the clear.
**thing to note**
If you're using windows, after downloading the needed .rar file, the file could be blocked. Just right click the .rar file and you should have the option to unblock the file and apply it.
There's also a dowgrade checker out there to make sure you dont have a corrupt 9.2 downgrade before you start installing cfw and whatnot.
