Hacking Undo Region Changing

[DBOA]

Hello everyone... Thanks for the time reading this...

I have changed the region from my old 3ds from USA to EUR for whatever reason, never had a problem with that, now i'm trying to play some games with friends at work, but some games can't be player on different region 3DSs.

I want to undo the change.
Does anyone know if I just just redo the process with my original region, or there's a war to undo it?

Maybe if I restore the original NAND and do the CFW process all over again?


Any help is apreciated.

Restore should be enough.
