Ok, so in an attempt to get Sun and Moon early I grabbed my old 3ds, which was updated to 9.2.0, and decided to hack it. I put homebrew on there and did the 2.1.0 ctrtransfer and everything was working fine (was using this guide https://ianburgwin.net/ez3ds/checkfw?model=Old&major=9&minor=2&revision=0&nver=20®ion=U ). However once I finished that I tried to do the third step, installing arm9loaderhax, but I could no longer open Homebrew in my 3DS. In a fit of frustration I whiped my SD card and put in a backup of the SD card before it had done the 2.1.0 ctrtransfer. I put in the SD card and tried to load Browserhax, but it crashes everytime and I dont know what to do. Is my 3DS no longer able to use Homebrew now?
Did you restore the backup? Big no no if you did that.
Also, since you have to update your 3DS during the arm9loaderhax installation, you needed to update your Homebrew files as well (if you were using a secondary exploit) (if you were primarily using Browserhax for everything, you dun goofed)
Also, you should've been able to access Homebrew since you install the HBL.cia before entering Homebrew anyways.
