Hello people. I have some problems.
I have 2 different 3DS
1- Old 3DS XL
2- New 2DSXL
I was playing online games with my old 3ds with Sky3ds card. After that i made CFW for it. But now i cannot connect to the internet. There is an error code 003-2101.
Another New 2DSXL is connecting still...
although i ended up accidentally changing my nand with no way of going back bc i didn't know you needed a gamecube controller to restore it (i have a wii minus/1.1, which doesn't have gamecube controller support)
and if i find the sd card i have my NAND backed up on, i can not only restore the NAND if i solder the right part in, but i can also put my NAND on dolphin, then i can play dolphin online, like PMEX Remix or MKWii Riibalanced
