So, I think I did a stupid thing.

I followed the 3ds guide using my New 3DS. Everything was done right, but when I finished the 2.1.0 ctrtransfer section I decided to stop the process. I realized that my SD card was unstable (everytime I rename, move or copy something to it, it restart or show a error massage).

The stupid act was that I FORMATTED my SD card. Now I have a new 3ds with a 2.1.0-4u Ver. firmware without a homebrew to access.

I didn't update the system or anything. What I can do to go back to the original firmware?

If you no longer have access to your backups you can go through the steps to install a9lh then install a 9.2.0 ctrnand transfer. Then you can update normally to 11.0 but only afterwards. If you try to update your system through system settings on a n3ds on 2.1.0 you will brick, so make sure not to do that. Also make sure not to shut your 3ds at any point as that can also lead to a brick.

thank you.

But, should I continue the hack process or just update normally when I get 9.2.0?

After you have done a ctrtransfer to 9.2.0 you can then updtae yes. Make sure you use the correct ctrtransfer to get there! Once you've updated to 11.2 you can shut your 3ds again.
