I got my old 3DS running on the CFW luma3ds (a9hl, FBI, HBL) and it is updated to the newest firmware. When i try to install a .cia or while playing games which are already installed i quite often get an error which says: SD card removed. please press home button to return. After a couple retries it starts to work well (even without taking the SD card in and out) so this thing confuses me. I use a micro SD card with an adapter on my 3DS. Reformated sd card and tried with different adapters but this doesnt solve the problem. Is this even a valid option or should i consider buying a normal sized sd card for my 3DS? I also have another question, if someone would install an USA (regionfree) version of a game on an EUR system could it still be updated through the eshop or would this be impossible? Thanks in advance.
