me too. or three. or N3.
I had the green light goes out/no tones. Actually, it was like this for a long time now but finally got around to fixing it. I tried the usb stick FAT32 one extracted file, but no love. tried 6 times. tried without USB, weith, didn't matter.

I don't seem to have access to SD card from bottom slot, and there are maybe secure-torx screws along the side keeping it in place? I'd try the flashing SD if I could get in there.

Suggestions?
