I'd remove the memory cards... then hold down the power button until it powers down.

No reset on X5ii  Hold down power button for ten or more seconds.

  Did my X5ii just crash??!? It suddenly switch to a blue screen with a list of what looks like registers. And I can't power it off now.

Yup, seen that before, I thought maybe I had hallucinated that it was rotated 90 degrees. Hold the power button down for 10+ seconds.

I wonder what happened.
 
These errors happen with very bad files of very bad firmware errors. I crashed once my X5 due to a bad UI designed by me that did not work. 
 
You should change the microsds, or at least try to check them for errors. 
 
On what song did this happen? IF you remember, you should erase the song.

How can X5ii generate 7V if it has only 3.7V battery? I thought the voltage of any portable player is limited by its power source.

This actually happened while the player was idle. I pressed to power button to shut it off and that happened.

Yes, if a card isn't removed properly or hiccups in any way, Windows can scan it and usually repair errors whilst preserving the contents.  Other OS systems can do the same.

DC to DC step up converter. They are not extremely efficient, and it costs current drain.
Here is an example just picked at random

  1st time I've seen a custom dual entry cable for the HP50's. Very interesting and I have to ask - how does it sound?? I'm going to hate the answer as I just got rid of mine due to build and comfort issues. Sure hope they do a HP70!!

Are there any sample music files freely downloadable that will really show off the X5ii? Or failing that, any online that would be good to purchase?  I've started ripping my own CDs but it would be interesting to compare what I have to what people consider an example of the best.
 
(BTW: where is a good place to ask about OSX software for ripping CDs and organising tracks?)

Worked. Thanks. All back to normal now.

Try these DSD samples from Oppo Digital, but make sure you just load the 2 channel tracks on your X5ii.

Fair warning that one of the tracks actually has quite a bit of static/noise, but it's DSD clear as a bell. :wink_face:

Sometimes the screen would go funny on the original X5 as well. A reset is all it takes, nothing to worry about and it really shouldn't happen often at all (only happened to me once with the original X5 since launch day). FiiO said its the actual RAM for the screen that needs to be reset on the original so I suspect that is what's happened here as well.

I'm just wondering what this higher voltage means. If there's more voltage as compared to X5 1st gen, then it means more current => more current * more voltage = more power. However, X5ii actually outputs less power than the 1st gen. There can't be higher voltage if the power is the same or lower, right? So what does it really mean?
 
For specs, see the chart here http://www.headfonia.com/review-fiio-x5-second-generation-part-1/2/

 

[T.R.A.N.C.E.]

Higher internal voltage rails means certain opamps can be used which otherwise couldn't be, it also means certain opamps are operating in at a more suitable voltage which can lead to better sound quality. Higher voltage rails does not necessarily mean higher power output, as is the case with X5ii, the higher voltage is primarily for better sound quality it seems.
