Er...I suppose that if transfer a 2.1.0 ctrnand directory to a n3ds is possible, doing this without installing n3ds titles will also be fine.
well, anyway i'll have a try. thanks
I've already created a ctrtransfer.bin from a old3dsLL (9.1.0-20J and with A9LH). when i transfered it to my n3ds in the same region (11.0 also with A9LH) Decrypt9 recalls a success message normally, but I couldn't boot the sysnand anymore as well as the safe mode. A9LH is still working...
