Ok..... here goes.....
I have an original launch model 3DS on 10.7.0-32U firmware, and non-XL New 3DS on firmware version 10.6.0-31U. Neither of these are hacked...... yet. I would also like to transfer everything I can from the O3DS to the N3DS, but from what I have gathered it would be best if I hack them first before doing this, since it would otherwise require me to upgrade to firmware 11.
I just got the N3DS and pretty much have nothing on it, so I am planning to hack that first since I wouldn't risk losing anything. Of the exploitable games, I have Smash and Freakyforms, sounds like it would be easier for me to just use freakyforms than any other type of hack.
So I am looking at this guide here:
https://github.com/Plailect/Guide/wiki/Part-1-(Homebrew)
And I am also looking at the Freakyforks hack page here:
http://plutooo.github.io/freakyhax/
And that link seems to concentrate on just getting Homebrew Launcher to run. Is this necessary to hack it further, or is this a "homebrew only, nothing permanently installed" kind of hack?
Then, the 9.2.0 downgrade instructions on this link:
https://github.com/Plailect/Guide/wiki/Part-2-(9.2.0-Downgrade)
Also mentions that it's best if your 3DS is "reset", while I can't do that for my O3DS, the N3DS was pretty much that way since I just bought it, though I did have to go through initial setup to be able to even use it. Is this what they mean, or is there a way to launch the hack during the initial setup to even further reduce chances of a brick?
The downgrade page also mentioned a save manager, is it possible to run this before you do anything that can cause any kind of permanent modification to the 3DS? Losing my save data is exactly what I was worried about with the O3DS. Can these saves only be restored to the same 3DS, or a different one? If I manage to do a backup and then downgrade, can I restore the backup that was made when the 3DS was on a newer version?
The instructions also seem to be written from a much older time when menuhax and browserhax were viable, I am not sure how to use freakyforms instead of menuhax for the 9.2.0 downgrade, or the further steps.
Do these downgrade instructions work on any 3DS that's not on version 11? Is it possible to downgrade a N3DS all the way down to 2.1.0 for arm9loaderhax? 2.1.0 was way way before the N3DS's time.
Once I am fully hacked, can I still do everything I normally could do on a non-hacked system? Play online, use the eshop, install game updates/patches, etc? I am not talking about roms, but software I actually purchased on the eshop or have on cart. Could new games possibly have some kind of security that prevent them from running on a hacked system? Again, I am talking about legally purchased games on cart, not roms.
And finally, after I manage (assuming I don't screw up and brick) to fully hack my N3DS, what would be the best way to do a system transfer before I fully hack my O3DS? I don't want to fully hack my O3DS before I do a transfer since there are many steps where it can go wrong AND there is a high chance the 9.2.0 downgrade can fail since I have five years of downloads on it, as well as the ambassador program and DSiWare, just about everything that could possibly get in the way of the downgrade and brick it. Which is why I want to hack it as little as possible just long enough to perform a system transfer to the fully hacked N3DS before I format and fully hack the O3DS. Can I do a system transfer before any of the downgrade steps?
