I don't want my firmware anymore

[cainy]

My 3ds is running 9.6.0 and I want to downgrade it to 9.2-9.5 but I don't know how. I need to know how, can you guys help?

Unfortunately, downgrading is only possible if you're at 9.2.

You would need a NAND backup and hardmod

Or get a 3DS with firmware less than 9.2

If you have a backup of your nand when it was on 9.2-9.5, you could get a hardmod(either sending your 3DS to someone to do it or doing one yourself) and restore that backup. If you never made a backup, then your only option is to get another 3DS.
