Background: I'm a noob but I managed to downgrade my small n3DS (forgot which firmware) and install a CFW following tutorials. Now I'm trying to do the same for my partner's n3DS XL on firmware 9.9.0-26E. At first I was running into problems with the browser nag message but managed to get browser hax working and then install menuhax using this guide. https://gbatemp.net/threads/browserhax-is-still-working.400991/ I then used Safesysupdater to downgrade like I did with my n3ds. During the downgrade I was so happy because it seemed to be working on the first try. My partner then pointed out that the battery was low so I quickly plugged the charger in. That's when everything went wrong. I forget exactly what happened but after a little bit, a Nintendo error message came up telling me to contact Nintendo. I shat myself, thinking I'd brick the n3ds. Luckily after a few moments of panic, I realised I could still boot it if I took the SD card. Problem: Every time I try browserhax, it gets stuck exactly at the dark yellow (orange?) screen and then an error message appears. "an error has occurred, please close any soft ware and restart your system" I've tried: Formatting the SD card Deleting the files and replacing them on the SD card Different internet connection The same thing over and over again. Any ideas why browserhax stopped working or anyway around it?
