I have been following this guide to downgrade my o3ds 18.104.22.168E to 2.1 (https://3ds.guide/installing-arm9loaderhax) and got stuck at section V. But now it has a soft brick. When I want to turn it on it blinks blue for a second and does nothing. I followed this guide to repair () and got the o3ds start up again. But then I have to copy/paste a file (luma inside) and that's where I fail because I don't have FBI installed. The only thing I have is a copy of my SD from when I was on 2.1, but my system says it's on 22.214.171.124E. Someone suggested to go into Hourglass9 and restore my nand and keep a9lh. So I checked my sd-card and found NANDmin.bin but I don't want to do something I'm not sure about. Can I do this? And if it works, can I proceed with the guide I was following? Also, I have succesfully followed this guide () on a n3ds with 126.96.36.199E. During this process my n3ds was downgraded to 2.1, but now my system says 188.8.131.52E again. Is this for real this version? Because I don't want to accidentally update my n3ds and then brick it!
