I tried it on my 2DS, but I get get an error message and reboot, when I launch the DS Profile Settings.
I downgraded my sysnands (9.2) mset to 6.0.x and then launched the CakesROP.nds with my flashcard and 6.x ropCustom.txt (rxTools.dat). Both writing and veryfiying was successfuly. I didn't tried mset 4 yet because of the risk of bricking with 2DS devices.
rxTools doesn't support mset 6.x version of CakeHax yet. You can update and compile yourself though. Make sure the CakeHax submodule is updated to HEAD.
