According to 3dsbrew, veryslowpidhax, which is still not patched and would take about a month to complete, is an exploit that gain access to all privileges! That means that if someone has the patience to run it, you could easily downgrade straight from 11.2, without any dsiware!
So basically what your saying it would take up to a month to downgrade from 11.2 with this method? i just want CFW on my 3ds without having to have another hacked 3ds
