9.2.0 Update - GamerTunerit/Guide GitHub Wiki
Most 3DS CFW applications and software are designed for use with a SysNAND version between 9.0.0 and 9.2.0. If you are below version 9.0.0, you will need to use this guide to update your 3DS without going all the way to the latest version.
If you are on versions 9.0.0 through 10.7.0 you can just follow the instructions here.
If you already have a RedNAND setup, this guide deals exclusively with SysNAND and you should follow all instructions from within or applying to SysNAND.
Note that the terms EmuNAND and RedNAND refer to slightly different implementations of the same concept.
You SHOULD make a SysNAND backup with Decrypt9 as soon as you are on 9.2.0.
The numbers in the body of the chart refer to the last number of your version (which corresponds to the browser version installed to the system). In the case of "5.0.0-7U" for instance, you would follow the ">6" guide in the 5.X.X column because -7 is above 6. If you had "5.0.0-4U" however, you would follow the "2-6" guide in the 5.X.X column because -4 is between 2 and 6.
