1) and 2) are literally the same effort so why using slowhax in the first place1. If you are total NOOB use waithax to gain A11 kernel access, then wait for 1 hr 25 min and use 3dsx version of FBI to install a Legit CIA,
2. If you are a semi-NOOB and have some knowledge about 3DS then use fasthax and follow the same instructions, just it would be lot faster say about 50 sec.
3. If you are moderate/professional at 3DS hacking follow 3ds.guide and A9LH your 3DS to get all games for free using just TIKdevil or TIKshop! Then use eshop, I don't like FREeshop that much.
3) its easy, you dont need to be an enginner to follow simple steps
