So I was trying to install the patched agb_firm to play gba games on my old 3ds with rx tools and the first time I tried to install the CIA it have me an error so I went to delete the Tittle ID 0004013800000202.cia but I didn't notice the 2nd screen and I deleted something that had the right Tittle ID but on the bottom screen it was in the "Builder" section not the CTR section. After restarting everything seemed fine and I was able to install the CIA but as soon as I tried to launch something on Emunand the controls stop working. The 3ds doesnt freeze because I can see the little logos moving like they do when you select something but it's just stuck on the home screen. On system nand through gateway I can go into FBI though gateways game launcher but I have no idea how to reinstall the "builder" I deleted or if it's even possible.
