I'm using the setup for Cakes right now (as described in the
tutorial), but thanks for the offer!
I think there is progress for that. For instance, OTPHelper will automate a lot of the actions like you said (and will check the sysNAND to prevent most if not all bricks). SafeA9LHInstaller pretty much does in seconds what compiling and running your console-specific 3DSX installer did, and from what I've seen it has been reliable. I think it was getting the OTP that was the most excruciating part, but after that, the installation is easy. Just make sure you check your OTP before installing A9LH to your console (OTPHelper does this)
