Btw. does anyone know how the hell redownload on e-shop works? Game is not linked to Nintendo ID on e-shop, and yet I can redownload it on different SD card. :D
CHMM2 seems to increase rate of FBI booting succesfully as well. I just used L+R+A to leave CHMM2 and FBI booted without problem. Someone recommended that some pages later. I will check it again and i'll send you an reply again to confirm it. Then you can pinn this in first post. ;)
Use DLAN from Settings -> Data management. It's faster than FTP. But still, best is to just to open your N3DS and put the card into PC with USB adapter. And dude, it's typical + screwdriver... You can unscrew this even with knife.
I don't know yet. I will check if I can still re-download it on different SD card. If so, that would mean that some ticket/access sygnature is on sysnand. But I'm not sure.
No, it's more like just pre-installed games from bundled consoles. Because I installed Super Smash Bros Legit CIA, then deleted it completely off my SD Card and yet I could redownload it from e-shop. (What I did indeed.)
Try to run head tracking demo and then FTPBrony. After that try to run FBI. Worked for me. Probably only FTPBrony increases the boot success rate, but me and my friend were using head tracking demo too. Worked.
I wonder if you can install all of them one by one and then redownload anything you would want at the moment from e-shop. How this "ticket" for e-shop works?
