I've noticed that on gbatemp there are many people, including me, who have tried to downgrade multiple times but always get softbricks. In my case, sysUpdater installs all of the cias correctly and reboots, but comes up with the "An error has occurred. Please reboot the 3ds" or something similar to that. I get that error whenever I reboot, except of course when booting into recovery. Now, why I am posting this is because the way all the people I've seen who have this problem have formatted their 3ds to get it working again. However, I am not willing to do this. If anybody has the same or similar problem, please reply to this thread how you fixed it (or if you haven't fixed it, explain what you think is causing the problem). Thanks!
