Issue when opening dumptool.nds "this isn't a DSi!"

[euvhism]

Hello, I have an issue with the file dumptool.nds, I have a new3DS
Firstly I installed manually TWIlight Menu++ and everytime I clicked on dumptool - zoogie - Dump Dsi NAN w/ nocash footer, it just told me "dumpTool v1.0 -zoogie
This isn't a DSi!
Hold Power to exit"
So I can't do a backup NAND.
I tried to install TWIlight Menu ++ by Universal-Updater then manually add the dumptool file but still the same message, I also tried to click on everybuttons of the DS but only the home and power buttons works.
