Actually. There is something I can say.
.
... you couldn't find a single post about it?
A
Single
Post?
Granted, nothing on the recent cfw section, which you posted in, has an explicit title asking about this, but let me do some quick googleing just to prove how easy it is to find an answer without further trashing a forum already flooded with noobs.
The search term 'downgrade 3ds 11.0' provides the following result after a few hardmod tutorials:
http://wololo.net/2016/05/12/latest-3ds-firmware-hacked-3ds/
The term, 'gbatemp 3ds downgrade 11.0' will give on the second result a thread which answers your question and is written by Plailect, an extremely trustworthy user who wrote a guide which is basically the 3ds hacking Bible.
Finally, when clicking 'new thread', an answer is given to you immediately, in an attempt to prevent the trashing of forums in cases just like yours:
- It is currently impossible to install (non-legit) CIA files or use CFWs if your 3DS is above firmware 9.2! All firmwares (10.7 and below) can be downgraded.
Furthermore:
- Please check our forums and Google to get the latest up-to-date information on your CFW and get answers to any questions you might have before asking them.
In conclusion, a big
shame on you for not bothering to Google, or even bother to read a 2-paragraph-long message that was explicitly put right in front of you.
I hope this was readable and not insulting, as I wrote this extremely late. Forgive me if I did insult you, I didn't mean to
