It's been a bit over a year or so since I got it, and my N3 seems to no longer be recognizing the SD cards I have inserted into it; I've tried multiple cards now, both 128GB and 64GB formatted to exFAT and FAT32, fully reformatted them all twice and I'm still getting nothing. The N3's display screen says "No memory card Please insert memory card" when I try to access the files on it, and I can't even update or change the firmware version on it, as when I try I get the message Operation failed Upgrade file not found" despite the fact I have the .upt file in the root of the SD card inserted into it. It was running the 3.0 custom firmware from this thread if I remember right. Oddly when I plug it into my computer (Windows 10 PC) it is recognized as a thumb drive and I can access all the files I had loaded to it. The N3's Bluetooth functionality still seems to be working fine, as it seems I can stream audio from my phone to it no problem. Anyone have any ideas on how I can fix this?
Have you tried a reset of the N3?
