yesterday i decided to switch out the SD cards because the one i was using for my 3DS (for over 1 - 2+ years at this point) could no longer insert in any SD card drive other than the one in my 3DS... it was a 16GB one and i switched it out with a 32GB one, then i got the ARM11 error screen, then i switched it back to my main one.... and i STILL got the ARM11 screen... no matter how many things i tried to do it still wouldnt work, i was so upset............. PLEASE HELP ME!!!!!!!!!!!
