Damn, me too.
So I'm able to access the eShop on my 2nd 3DS fine, it just won't let me download software without a NNID. I'm able to download stuff on my first 3DS though. I think it may be because Nintendo still sees my first 3DS as being linked to my old NNID. Anyways, try getting the newest release of Decrypt9 from here, redownloading the blank nnidsave.bin from here and injecting it into your 3DS. Maybe you guys accidentally injected your original nnidsave.bin?If anyone figures how to remove this error please let us know.
Thank you for even trying - really appreciate it.
If that doesn't work, follow the first part of the guide to get rid of error 002-0102 if you can. At the very least it would reduce the number of things different in our setup and make it easier to troubleshoot what exactly is wrong.
