v2 is working fine on me o.o , but sometimes is just white screen. If re-apply ds profile exploit, it will work again ... is seems broken on somewhere o.o . both my 32 GB UHS-1 Class 10 Premium microSD card (transcend, it say 300x, last month i buy this card) and old crappy microSD with class 4 (local product, 3 years old) is working fine o.o
I don't think re-installing the exploit is needed. There's a readme in the padgen file, and it says this:
NOTE: If you get no text on screen, reboot your 3DS and try again.
