Sorry for my English if there is any mistake Some time ago, did some DSiWareHax for softmodding a 3DS XL. Before that, I 'unlink' my NNID from my 3DS by modifying data from CTRNAND ('Removing a NNID without formatting your device' https://3ds.guide/troubleshooting), so I thought there was no NNID linked... I did the System Transfer: neither NNID on my 3ds, nor in the 3ds xl. Now, I want to link my NNID on my 3ds but it says it is linked in other system. Today I called Nintendo Client Support and they say that NNID is linked to a 3ds xl, although there is other NNID in that 3ds xl... What can I do?
