i have purchased a new3ds in a game lot and its giving me the arm11 (core1) error on boot up. i have updated luma to the current system firmware which i have also updated via button combo on boot and same error. will not boot without the sd card also. all the files seem to be correct on the sd card and folder structure. i have tried https://3ds.hacks.guide/ctrtransfer.html this with no success. there is no nand on the sd card. i do have a r4+ card if that could be of use for unbricking. thanks in advance
