Try this to install menuhax:https://github.com/Plailect/Guide/wiki/Part-1-(Homebrew)
Ntr cheat engine is as equally good as gateway just install a9lh+luma3ds and you can have multiple emunand(I saw a member with 4 emunands)
I have done that on 2 n3ds and it worked flawlessly. Just follow pailects guide to the word and nothing can fail
U could launch GW from HBL (or directly if ur boot.3dsx is from GW.3dsx) after installing menuhax,also the setting exploit u used before will work too.
Yes, I really suggest U follow the guide, if u wanna use GW,u could keep a 9.0~9.2 emuNAND and boot GW from HBL(installed from cia) there.
Okay after all it's up to U
Fine do breaks and most of the time you will spend on the 3ds as the process in pc is just pure copy paste. A9lh is just easier and faster
It cant get bricked if you are careful. And the process nowadays isn't dangerous unless you can't or don't know how to properly read a guide. There's no excuse for not installing a9lh unless being blind. And the brick chance is non existent. What is existent is user error which is caused by the lack of proper reading.
Yes you can just make sure you follow the guide properly to the word so you can make the biggest number of backups you can
