I can't upgrade. It gets stuck at the very final step, when the bar is almost full. Is it supposed to take so long? Edit: Nevermind, got it to work, it was a format problem. Hey @FiiO, whenever I run a library update I end up with an Unknown Artist which has an Unknown Album but has no tracks inside, I'm guessing its a little bug, since I'm using the same SD card I used with the original X1 and it didn't show it.
