Homebrew O3DS Safe to format?

[bananapi761]

I've been wanting to downgrade my 10.3E O3DS for quite a while now, but I tried quite a few times and I always got a softbrick. I haven't tried downgrading again since the 10.4 update came out, because I didn't want to be stuck on 10.4.
According to some, formatting your system should fix the problem, but I have a lot of purchased content, save files, ambassador games, etc on my system. I found out that if you format, apps will still be on your SD, but invalidated, and you'll have to redownload them.

So I have some questions;
1. If I use the save data backup function, will I be able to restore the save file for each redownloaded game even after formatting?
2. Will my old eShop account be usable?
3. Will my theme used for menuhax still be usable?
4. Will the latest system update be downloaded after formatting?

Thanks for the help!

Hi, banapi! Sorry for the late reply, but I'll give you yes and no answers to your questions.

1. Yes!
2. Yes, you'll still be able to use it.
3. I'm pretty sure, considering it's on your SD card. Don't take my word for it though.
4. No, it will prompt you to update, but make sure you don't.

Hopefully that answered your questions!
