I managed to semi-brick myself during the 2.1 downgrade portion of the most recent hack method by half-mindedly playing Animal Crossing New Leaf and installing the update that comes with it (4.5, I believe). All I know is that I'm on old 3DS firmware and I've consulted with the IRC group about this and the only method that would work is to flash 11.2 on my system via a hardmod since the other method requires me to go into the browser or system settings, of which both won't work and are completely nonfunctional. Booting straight into the update screen works but trying to update to the most recent firmware is useless as it gets stuck indefinitely at about 95%. I have my NAND backup and everything and this is really my last hope, before I have to go out and buy a new N3DS. Contact me if you think you can help, thank you very much my friends.
