I am getting a 2ds and I heard it will be on firmware 6.0. But I don't know what CFW to use all I want to do is install cias on to emunand (obviously). But I am looking for whatever is the fastest and easiest to install.
Also is it a possible my 2ds will come on something above a cfw compatible firmware?
I'll tell you the best thing you can do:
*Create a NAND Backup and copy it to your computet.
*Install emunand
*Install rxTools
*Inject FBI and install sysupdater
*Use sysupdater in DEV MODE to update system nand to 9.2
*Set up autoboot themehax + autoboot rxTools
*Update emunand to 10.1 using system settings update feature
With all these things you'll be able to launch rxTools into emunand from coldboot, just by powering up your 2DS.

I have done all this, here is a little video that shows the end results:
