Ok. After some tries i was able to downgrade mi o3ds to 9.2 firmware. The next step i want to make is to install rxtools cfw. I was able to install sliderhax in my principal SD Card. The question is that i use at least two SD Cards (8 and 4 GB). After i install the cfw, can i use two SD Cards? Can i install sliderhax on my other SD Card? what recomendations can you give me? Also, i was banned from the eshop, once i install cfw, can i safely ask nintendo to unban mi NNID on emunad? Thanks in advance..
