I'm now confuse what you want to do now.So in the guide i should stop where it says
6. Update your 3DS again by going to System Settings, then "Other Settings", then going all the way to the right and using "System Update"
(Last step in Section III - Configuring Luma3DS).
And use this guide instead to make it 9.2.0?
https://github.com/Plailect/Guide/wiki/9.2.0-ctrtransfer
Also dont i need to unlink the SysNAND and EmuNAND?
I remember doing it when i installed RXTools, so that the EmuNAND wont effect all the "changes" i do in SysNAND (for instance system update it)
Normally if you following the guide correctly, It will take you back to SysNAND 9.2 or Lower (depend on the current FW before you do the change) at the end of Step 2.
At this point onward, Step 3 will guide you how to install A9LH. And after that you can update you sysNAND using System Settings.
So, my question is "What do you want to do?" Since I'm very confuse right now.
