i tried a luma version from 2017(v9) which is when the 3ds was modded and sd card formatted and it gave the same issue but i think the 3ds was stored in good conditions and it has no physical damage. ill try some of the older luma versions...
No, that would indicate a hardware problem.
All you should need is the Luma3DS boot.firm. If you had a very old version of B9S and Luma3DS before, it could be that your B9S is too old to work with the latest Luma3DS. Could also be a faulty SD...
i tried reinstalling the boot.firm file as well as godmode9 but it still gave me the flashing blue light as if the sd reader is broken. i don't have any of the original files on the sd card as it got formatted
@K3Nv2 I got some cheapies at wallys, that are pretty good, already have lost a few expensive ones (one falls out and gone, can't find) while cutting grass so bought some cheap ones, and of course never lose these cheap ones. (Cheap meaning only $35, compared to air buds which I only have 1 of 2 now)
