Homebrew Where should I start with ntrboothax?

[Treeko]

Okay so I got the R4i gold ordered from the sponsor of this lovely site, I want to unbrick a o3ds that I have stored away with a 9.2 nand backup on its 2gb sd card with ntrboothax, I have a few questions related to ntrboothax:-

1.Any kind of magnet works right?

2.What exactly does ntrboothax install, is it boot9strap?

3.Which guide should I follow, I've seen a few here on gbatemp specifically mentioning themselves as unbrick guides, should I just follow the 3ds guide for ntrboothax installation instead?

4.Can I get the R4 to work normally once I am done reviving my 3ds, to run nds roms again?

5.How high are the flashcard brick rates with ntrboothax?

1: Really any magnet strong enough to activate sleep mode. I actually have a neodymium magnet that is so powerful that can activate sleep mode without even touch the system. I don't think you need something that powerful, but that's what I use.
2: It's actually just called "NTRBoot," and it can really be used to do activate any B9S payload. So you can use it to install B9S, activate GodMode9, etc. Although it's best suggested to just install B9S with it.
3: Best guide around https://3ds.guide/ntrboot
4: If you are referring to the R4i Gold, you need to restore a backup to make it work again.
5: For the cart itself, no publicly reported bricks have happened to the carts. For the system, 0% chance of bricking.
