The first thing this guide will do is get you running Decrypt9, which is a multipurpose toolkit that will allow us to install the version 2.1.0, which contains a vulnerability that is needed for further exploitation of the system.

If you have already hacked your 3DS before and have a EmuNAND based CFW setup, this guide deals exclusively with SysNAND and you should follow all instructions from within or applying to SysNAND. Merk at EmuNAND og RedNAND refererer til litt forskjellige implementeringer av [det samme konseptet](http://3dbrew.org/wiki/NAND_Redirection).
