So I've made a mistake on one of my 3ds Xl and my sd corrupted when I had to load 2xrsa.3ds.guide in the browser. I used a new sd and I was able to install Arm9loaderhaxx. Problem is now I cannot revert back to 11.2. I've tried to via system setting but I would get an error. "An error has occurred the system will now restart" Is there anyway for me to manually install the FW 11.2 so I can complete my CFW setup?
