Hacking Bring back homebrew on cfw n3ds

[Dragonicleafy]

So i have Luma v9.1 and am unsure of what guide to follow. I bought a 3rd hand console where the first owner had cfw and the 2nd brought the console to factory settings, but it still has GM9 installed as well as other things, but i cant seem to boot homebrew via download and play app after setting it as a hb launch app via rosalina menu. I tried following the 3ds.hacks guide on finalizing setup but i cant launch it as it simply freezes the console. I also dont have the original files for the 3ds before the cfw installation as the seller didnt have any contact with the original owner. For any information that is needed, please ask.
