I can do the same with RxTools !





Not really. Alright, lets address a few points here:
Number 1 - I have no clue on how this thread is still active, it shoulve died hours ago yet I wake up to find this... stay classy gbafail.
Number 2 - We all know that "haha rxfools is evil because youll brick lolz xdddd" but what nobody is able to answer is
why. Even I didnt explicitly explain why myself.
Here's a small explanation as to why rxTools is unsafe to use: rxTools was pretty innovative in a lot of fronts, particularly the "tools" part - back then there was no such thing as nand partition dumps/injections, or file injections in a standalone fashion. The exisiting methods were clunky (for lack of a better word) and used "primitive" techniques (again, for lack of a better word).
This caused rxTools to have an endless amount of bugs (check the issues tab on GitHub, its quite impressive if I do say so myself...) that were never fixed - you can even say it simply does not work at all on some 2DS models due to a new unrecognized NAND (N3DS-only 1.8GB NAND on 2DS models), and some "features" like TWLN/TWLP dumps are outright broken.
But the grandest daddy of all issues is FBI injection: replacing a file inside a FAT filesystem should be easy right...? Well, theres something the devs didnt take into account - fragmentation. Thats right, the 3DS' OS isnt particularly fond of fragmented files, and has been known to cause boot-time softlocks (aka "black screen brick") on some occassions. This is ridiculous, and one of the many many reasons why Gateway has been panned as well - their downgrade to 4.x cause fragmentation of most files. So instead of having a small chance of bricking, GW has a bigger chance.
If anyone wants to, I might make a second post detailing why the CFW part sucks too, but since Im currenty typing on a tablet... yeah. Its awkward
EDIT: someone might argue "but why not use dukesrgs version?" well youre free to use it but even he himself has said it contained bugs. Besides the part where the CFW part wasnt modified *at all*.
